how to write a scientific essay uni

Writing the Scientific Paper

When you write about scientific topics to specialists in a particular scientific field, we call that scientific writing. (When you write to non-specialists about scientific topics, we call that science writing.)

The scientific paper has developed over the past three centuries into a tool to communicate the results of scientific inquiry. The main audience for scientific papers is extremely specialized. The purpose of these papers is twofold: to present information so that it is easy to retrieve, and to present enough information that the reader can duplicate the scientific study. A standard format with six main part helps readers to find expected information and analysis:

  • Title--subject and what aspect of the subject was studied.
  • Abstract--summary of paper: The main reason for the study, the primary results, the main conclusions
  • Introduction-- why the study was undertaken
  • Methods and Materials-- how the study was undertaken
  • Results-- what was found
  • Discussion-- why these results could be significant (what the reasons might be for the patterns found or not found)

There are many ways to approach the writing of a scientific paper, and no one way is right. Many people, however, find that drafting chunks in this order works best: Results, Discussion, Introduction, Materials & Methods, Abstract, and, finally, Title.

The title should be very limited and specific. Really, it should be a pithy summary of the article's main focus.

  • "Renal disease susceptibility and hypertension are under independent genetic control in the fawn hooded rat"
  • "Territory size in Lincoln's Sparrows ( Melospiza lincolnii )"
  • "Replacement of deciduous first premolars and dental eruption in archaeocete whales"
  • "The Radio-Frequency Single-Electron Transistor (RF-SET): A Fast and Ultrasensitive Electrometer"

This is a summary of your article. Generally between 50-100 words, it should state the goals, results, and the main conclusions of your study. You should list the parameters of your study (when and where was it conducted, if applicable; your sample size; the specific species, proteins, genes, etc., studied). Think of the process of writing the abstract as taking one or two sentences from each of your sections (an introductory sentence, a sentence stating the specific question addressed, a sentence listing your main techniques or procedures, two or three sentences describing your results, and one sentence describing your main conclusion).

Example One

Hypertension, diabetes and hyperlipidemia are risk factors for life-threatening complications such as end-stage renal disease, coronary artery disease and stroke. Why some patients develop complications is unclear, but only susceptibility genes may be involved. To test this notion, we studied crosses involving the fawn-hooded rat, an animal model of hypertension that develops chronic renal failure. Here, we report the localization of two genes, Rf-1 and Rf-2 , responsible for about half of the genetic variation in key indices of renal impairment. In addition, we localize a gene, Bpfh-1 , responsible for about 26% of the genetic variation in blood pressure. Rf-1 strongly affects the risk of renal impairment, but has no significant effect on blood pressure. Our results show that susceptibility to a complication of hypertension is under at least partially independent genetic control from susceptibility to hypertension itself.

Brown, Donna M, A.P. Provoost, M.J. Daly, E.S. Lander, & H.J. Jacob. 1996. "Renal disease susceptibility and hypertension are under indpendent genetic control in the faun-hooded rat." Nature Genetics , 12(1):44-51.

Example Two

We studied survival of 220 calves of radiocollared moose ( Alces alces ) from parturition to the end of July in southcentral Alaska from 1994 to 1997. Prior studies established that predation by brown bears ( Ursus arctos ) was the primary cause of mortality of moose calves in the region. Our objectives were to characterize vulnerability of moose calves to predation as influenced by age, date, snow depths, and previous reproductive success of the mother. We also tested the hypothesis that survival of twin moose calves was independent and identical to that of single calves. Survival of moose calves from parturition through July was 0.27 ± 0.03 SE, and their daily rate of mortality declined at a near constant rate with age in that period. Mean annual survival was 0.22 ± 0.03 SE. Previous winter's snow depths or survival of the mother's previous calf was not related to neonatal survival. Selection for early parturition was evidenced in the 4 years of study by a 6.3% increase in the hazard of death with each daily increase in parturition date. Although there was no significant difference in survival of twin and single moose calves, most twins that died disappeared together during the first 15 days after birth and independently thereafter, suggesting that predators usually killed both when encountered up to that age.

Key words: Alaska, Alces alces , calf survival, moose, Nelchina, parturition synchrony, predation

Example Three

We monitored breeding phenology and population levels of Rana yavapaiensis by use of repeated egg mass censuses and visual encounter surveys at Agua Caliente Canyon near Tucson, Arizona, from 1994 to 1996. Adult counts fluctuated erratically within each year of the study but annual means remained similar. Juvenile counts peaked during the fall recruitment season and fell to near zero by early spring. Rana yavapaiensis deposited eggs in two distinct annual episodes, one in spring (March-May) and a much smaller one in fall (September-October). Larvae from the spring deposition period completed metamorphosis in earlv summer. Over the two years of study, 96.6% of egg masses successfully produced larvae. Egg masses were deposited during periods of predictable, moderate stream flow, but not during seasonal periods when flash flooding or drought were likely to affect eggs or larvae. Breeding phenology of Rana yavapaiensis is particularly well suited for life in desert streams with natural flow regimes which include frequent flash flooding and drought at predictable times. The exotic predators of R. yavapaiensis are less able to cope with fluctuating conditions. Unaltered stream flow regimes that allow natural fluctuations in stream discharge may provide refugia for this declining ranid frog from exotic predators by excluding those exotic species that are unable to cope with brief flash flooding and habitat drying.

Introduction

The introduction is where you sketch out the background of your study, including why you have investigated the question that you have and how it relates to earlier research that has been done in the field. It may help to think of an introduction as a telescoping focus, where you begin with the broader context and gradually narrow to the specific problem addressed by the report. A typical (and very useful) construction of an introduction proceeds as follows:

"Echimyid rodents of the genus Proechimys (spiny rats) often are the most abundant and widespread lowland forest rodents throughout much of their range in the Neotropics (Eisenberg 1989). Recent studies suggested that these rodents play an important role in forest dynamics through their activities as seed predators and dispersers of seeds (Adler and Kestrell 1998; Asquith et al 1997; Forget 1991; Hoch and Adler 1997)." (Lambert and Adler, p. 70)

"Our laboratory has been involved in the analysis of the HLA class II genes and their association with autoimmune disorders such as insulin-dependent diabetes mellitus. As part of this work, the laboratory handles a large number of blood samples. In an effort to minimize the expense and urgency of transportation of frozen or liquid blood samples, we have designed a protocol that will preserve the integrity of lymphocyte DNA and enable the transport and storage of samples at ambient temperatures." (Torrance, MacLeod & Hache, p. 64)

"Despite the ubiquity and abundance of P. semispinosus , only two previous studies have assessed habitat use, with both showing a generalized habitat use. [brief summary of these studies]." (Lambert and Adler, p. 70)

"Although very good results have been obtained using polymerase chain reaction (PCR) amplification of DNA extracted from dried blood spots on filter paper (1,4,5,8,9), this preservation method yields limited amounts of DNA and is susceptible to contamination." (Torrance, MacLeod & Hache, p. 64)

"No attempt has been made to quantitatively describe microhabitat characteristics with which this species may be associated. Thus, specific structural features of secondary forests that may promote abundance of spiny rats remains unknown. Such information is essential to understand the role of spiny rats in Neotropical forests, particularly with regard to forest regeneration via interactions with seeds." (Lambert and Adler, p. 71)

"As an alternative, we have been investigating the use of lyophilization ("freeze-drying") of whole blood as a method to preserve sufficient amounts of genomic DNA to perform PCR and Southern Blot analysis." (Torrance, MacLeod & Hache, p. 64)

"We present an analysis of microhabitat use by P. semispinosus in tropical moist forests in central Panama." (Lambert and Adler, p. 71)

"In this report, we summarize our analysis of genomic DNA extracted from lyophilized whole blood." (Torrance, MacLeod & Hache, p. 64)

Methods and Materials

In this section you describe how you performed your study. You need to provide enough information here for the reader to duplicate your experiment. However, be reasonable about who the reader is. Assume that he or she is someone familiar with the basic practices of your field.

It's helpful to both writer and reader to organize this section chronologically: that is, describe each procedure in the order it was performed. For example, DNA-extraction, purification, amplification, assay, detection. Or, study area, study population, sampling technique, variables studied, analysis method.

Include in this section:

  • study design: procedures should be listed and described, or the reader should be referred to papers that have already described the used procedure
  • particular techniques used and why, if relevant
  • modifications of any techniques; be sure to describe the modification
  • specialized equipment, including brand-names
  • temporal, spatial, and historical description of study area and studied population
  • assumptions underlying the study
  • statistical methods, including software programs

Example description of activity

Chromosomal DNA was denatured for the first cycle by incubating the slides in 70% deionized formamide; 2x standard saline citrate (SSC) at 70ºC for 2 min, followed by 70% ethanol at -20ºC and then 90% and 100% ethanol at room temperature, followed by air drying. (Rouwendal et al ., p. 79)

Example description of assumptions

We considered seeds left in the petri dish to be unharvested and those scattered singly on the surface of a tile to be scattered and also unharvested. We considered seeds in cheek pouches to be harvested but not cached, those stored in the nestbox to be larderhoarded, and those buried in caching sites within the arena to be scatterhoarded. (Krupa and Geluso, p. 99)

Examples of use of specialized equipment

  • Oligonucleotide primers were prepared using the Applied Biosystems Model 318A (Foster City, CA) DNA Synthesizer according to the manufacturers' instructions. (Rouwendal et al ., p.78)
  • We first visually reviewed the complete song sample of an individual using spectrograms produced on a Princeton Applied Research Real Time Spectrum Analyzer (model 4512). (Peters et al ., p. 937)

Example of use of a certain technique

Frogs were monitored using visual encounter transects (Crump and Scott, 1994). (Sartorius and Rosen, p. 269)

Example description of statistical analysis

We used Wilcox rank-sum tests for all comparisons of pre-experimental scores and for all comparisons of hue, saturation, and brightness scores between various groups of birds ... All P -values are two-tailed unless otherwise noted. (Brawner et al ., p. 955)

This section presents the facts--what was found in the course of this investigation. Detailed data--measurements, counts, percentages, patterns--usually appear in tables, figures, and graphs, and the text of the section draws attention to the key data and relationships among data. Three rules of thumb will help you with this section:

  • present results clearly and logically
  • avoid excess verbiage
  • consider providing a one-sentence summary at the beginning of each paragraph if you think it will help your reader understand your data

Remember to use table and figures effectively. But don't expect these to stand alone.

Some examples of well-organized and easy-to-follow results:

  • Size of the aquatic habitat at Agua Caliente Canyon varied dramatically throughout the year. The site contained three rockbound tinajas (bedrock pools) that did not dry during this study. During periods of high stream discharge seven more seasonal pools and intermittent stretches of riffle became available. Perennial and seasonal pool levels remained stable from late February through early May. Between mid-May and mid-July seasonal pools dried until they disappeared. Perennial pools shrank in surface area from a range of 30-60 m² to 3-5- M². (Sartorius and Rosen, Sept. 2000: 269)

Notice how the second sample points out what is important in the accompanying figure. It makes us aware of relationships that we may not have noticed quickly otherwise and that will be important to the discussion.

A similar test result is obtained with a primer derived from the human ß-satellite... This primer (AGTGCAGAGATATGTCACAATG-CCCC: Oligo 435) labels 6 sites in the PRINS reaction: the chromosomes 1, one pair of acrocentrics and, more weakly, the chromosomes 9 (Fig. 2a). After 10 cycles of PCR-IS, the number of sites labeled has doubled (Fig. 2b); after 20 cycles, the number of sites labeled is the same but the signals are stronger (Fig. 2c) (Rouwendal et al ., July 93:80).

Related Information: Use Tables and Figures Effectively

Do not repeat all of the information in the text that appears in a table, but do summarize it. For example, if you present a table of temperature measurements taken at various times, describe the general pattern of temperature change and refer to the table.

"The temperature of the solution increased rapidly at first, going from 50º to 80º in the first three minutes (Table 1)."

You don't want to list every single measurement in the text ("After one minute, the temperature had risen to 55º. After two minutes, it had risen to 58º," etc.). There is no hard and fast rule about when to report all measurements in the text and when to put the measurements in a table and refer to them, but use your common sense. Remember that readers have all that data in the accompanying tables and figures, so your task in this section is to highlight key data, changes, or relationships.

In this section you discuss your results. What aspect you choose to focus on depends on your results and on the main questions addressed by them. For example, if you were testing a new technique, you will want to discuss how useful this technique is: how well did it work, what are the benefits and drawbacks, etc. If you are presenting data that appear to refute or support earlier research, you will want to analyze both your own data and the earlier data--what conditions are different? how much difference is due to a change in the study design, and how much to a new property in the study subject? You may discuss the implication of your research--particularly if it has a direct bearing on a practical issue, such as conservation or public health.

This section centers on speculation . However, this does not free you to present wild and haphazard guesses. Focus your discussion around a particular question or hypothesis. Use subheadings to organize your thoughts, if necessary.

This section depends on a logical organization so readers can see the connection between your study question and your results. One typical approach is to make a list of all the ideas that you will discuss and to work out the logical relationships between them--what idea is most important? or, what point is most clearly made by your data? what ideas are subordinate to the main idea? what are the connections between ideas?

Achieving the Scientific Voice

Eight tips will help you match your style for most scientific publications.

  • Develop a precise vocabulary: read the literature to become fluent, or at least familiar with, the sort of language that is standard to describe what you're trying to describe.
  • Once you've labeled an activity, a condition, or a period of time, use that label consistently throughout the paper. Consistency is more important than creativity.
  • Define your terms and your assumptions.
  • Include all the information the reader needs to interpret your data.
  • Remember, the key to all scientific discourse is that it be reproducible . Have you presented enough information clearly enough that the reader could reproduce your experiment, your research, or your investigation?
  • When describing an activity, break it down into elements that can be described and labeled, and then present them in the order they occurred.
  • When you use numbers, use them effectively. Don't present them so that they cause more work for the reader.
  • Include details before conclusions, but only include those details you have been able to observe by the methods you have described. Do not include your feelings, attitudes, impressions, or opinions.
  • Research your format and citations: do these match what have been used in current relevant journals?
  • Run a spellcheck and proofread carefully. Read your paper out loud, and/ or have a friend look over it for misspelled words, missing words, etc.

Applying the Principles, Example 1

The following example needs more precise information. Look at the original and revised paragraphs to see how revising with these guidelines in mind can make the text clearer and more informative:

Before: Each male sang a definite number of songs while singing. They start with a whistle and then go from there. Each new song is always different, but made up an overall repertoire that was completed before starting over again. In 16 cases (84%), no new songs were sung after the first 20, even though we counted about 44 songs for each bird.
After: Each male used a discrete number of song types in his singing. Each song began with an introductory whistle, followed by a distinctive, complex series of fluty warbles (Fig. 1). Successive songs were always different, and five of the 19 males presented their entire song repertoire before repeating any of their song types (i.e., the first IO recorded songs revealed the entire repertoire of 10 song types). Each song type recurred in long sequences of singing, so that we could be confident that we had recorded the entire repertoire of commonly used songs by each male. For 16 of the 19 males, no new song types were encountered after the first 20 songs, even though we analyzed and average of 44 songs/male (range 30-59).

Applying the Principles, Example 2

In this set of examples, even a few changes in wording result in a more precise second version. Look at the original and revised paragraphs to see how revising with these guidelines in mind can make the text clearer and more informative:

Before: The study area was on Mt. Cain and Maquilla Peak in British Columbia, Canada. The study area is about 12,000 ha of coastal montane forest. The area is both managed and unmanaged and ranges from 600-1650m. The most common trees present are mountain hemlock ( Tsuga mertensiana ), western hemlock ( Tsuga heterophylla ), yellow cedar ( Chamaecyparis nootkatensis ), and amabilis fir ( Abies amabilis ).
After: The study took place on Mt. Cain and Maquilla Peak (50'1 3'N, 126'1 8'W), Vancouver Island, British Columbia. The study area encompassed 11,800 ha of coastal montane forest. The landscape consisted of managed and unmanaged stands of coastal montane forest, 600-1650 m in elevation. The dominant tree species included mountain hemlock ( Tsuga mertensiana ), western hemlock ( Tsuga heterophylla ), yellow cedar ( Chamaecyparis nootkatensis ), and amabilis fir ( Abies amabilis ).

Two Tips for Sentence Clarity

Although you will want to consider more detailed stylistic revisions as you become more comfortable with scientific writing, two tips can get you started:

First, the verb should follow the subject as soon as possible.

Really Hard to Read : "The smallest of the URF's (URFA6L), a 207-nucleotide (nt) reading frame overlapping out of phase the NH2- terminal portion of the adenosinetriphosphatase (ATPase) subunit 6 gene has been identified as the animal equivalent of the recently discovered yeast H+-ATPase subunit gene."

Less Hard to Read : "The smallest of the UR-F's is URFA6L, a 207-nucleotide (nt) reading frame overlapping out of phase the NH2-terminal portion of the adenosinetriphosphatase (ATPase) subunit 6 gene; it has been identified as the animal equivalent of the recently discovered yeast H+-ATPase subunit 8 gene."

Second, place familiar information first in a clause, a sentence, or a paragraph, and put the new and unfamiliar information later.

More confusing : The epidermis, the dermis, and the subcutaneous layer are the three layers of the skin. A layer of dead skin cells makes up the epidermis, which forms the body's shield against the world. Blood vessels, carrying nourishment, and nerve endings, which relay information about the outside world, are found in the dermis. Sweat glands and fat cells make up the third layer, the subcutaneous layer.

Less confusing : The skin consists of three layers: the epidermis, the dermis, and the subcutaneous layer. The epidermis is made up of dead skin cells, and forms a protective shield between the body and the world. The dermis contains the blood vessels and nerve endings that nourish the skin and make it receptive to outside stimuli. The subcutaneous layer contains the sweat glands and fat cells which perform other functions of the skin.

Writing a scientific paper.

  • Writing a lab report

What is a "good" introduction?

Citing sources in the introduction, "introduction checklist" from: how to write a good scientific paper. chris a. mack. spie. 2018..

  • LITERATURE CITED
  • Bibliography of guides to scientific writing and presenting
  • Peer Review
  • Presentations
  • Lab Report Writing Guides on the Web

This is where you describe briefly and clearly why you are writing the paper. The introduction supplies sufficient background information for the reader to understand and evaluate the experiment you did. It also supplies a rationale for the study.

  • Present the problem and the proposed solution
  • Presents nature and scope of the problem investigated
  • Reviews the pertinent literature to orient the reader
  • States the method of the experiment
  • State the principle results of the experiment

It is important to cite sources in the introduction section of your paper as evidence of the claims you are making. There are ways of citing sources in the text so that the reader can find the full reference in the literature cited section at the end of the paper, yet the flow of the reading is not badly interrupted. Below are some example of how this can be done:     "Smith (1983) found that N-fixing plants could be infected by several different species of Rhizobium."     "Walnut trees are known to be allelopathic (Smith 1949,  Bond et al. 1955, Jones and Green 1963)."     "Although the presence of Rhizobium normally increases the growth of legumes (Nguyen 1987), the opposite effect has been observed (Washington 1999)." Note that articles by one or two authors are always cited in the text using their last names. However, if there are more than two authors, the last name of the 1st author is given followed by the abbreviation et al. which is Latin for "and others".

how to write a scientific essay uni

What is "Science Writing?"

At first glance, science writing seems simple. It's writing about  topics related to science and can include works of creative nonfiction, nature essays, or scientific articles. But science writing is different from scientific writing. While scientific writing is usually intended for a specialized audience of scientists and researchers, science writing brings important scientific discoveries into the lives of the general public in creative and meaningful ways. Pieces of science writing can be very different from one another and can come in a number of formats. They can be long or short, detailed or generalized. They can be articles, books, videos, essays, podcasts, and more. 

This page serves as a guide for discovering credible science writing sources and connecting various fields of study. Scientists, students, educators, and writers can use it to find articles, videos, books, and other examples of science writing to support their interests. Whether you are an avid reader or an aspiring science writer, this guide is for you!

People who can help

An essay is a piece of academic writing which makes an evidenced argument in response to a question or series of questions. Some essays aim to prove something by developing a case, by reasoning, using examples and by taking a position. Essays may also involve providing clear explanations about a topic and allow you to demonstrate your understanding. In many cases, writing essays will involve gathering examples and evidence, and involves carrying out some initial research and reading.

Sometimes you will be assigned an essay question; in other cases, you will be given a topic and it is up to you to identify the possible questions you will seek to address in your essay.

At university, you will therefore usually be expected to read more widely and support your essay argument by referring to a more diverse range of sources and evidence.  Good essays will still need to meet important criteria that you have probably encountered at school and college: essays should be appropriately presented, clearly structured, and should demonstrate they have been proofread to check for clarity of expression and to minimise errors.  However, you will also be expected to follow academic conventions on how to reference existing research from books and journals as well as other appropriate sources.  You will need to engage critically with what has been written on the subject so that you explain the significance and importance of issues and examples.  You may also need to discuss the consequences and purposes of theories, methods and analyses presented by existing scholarship beyond identifying what has been said or done. 

For many students, writing essays at university may be difficult to begin with and it is very important to pay attention and try and respond to any feedback you receive.

Starting an essay

The first thing you should do is to read any guidance your school has provided and make sure you understand how your essay will be assessed. Pay particular attention to any assessment criteria or marking sheets, as well as any feedback you've been given previously.

  • Identify the question(s) to be addressed
  • Develop your thinking and reading to note down some initial ideas and thoughts
  • Don't become fixed in your early ideas: remain open minded, as you may wish to change your perspective as you read more
  • Consider the arguments against your view - how could you defend or rebut alternative positions
  • Begin to think of the structure of your essay and the sequence you wish to introduce points. Work towards sketching out an outline of how these points can be linked together
  • Start writing - some students find they can refine their ideas by trying to express them in written form
  • Be prepared to re-draft your work before final submission
  • Where possible, give yourself time to put the essay aside for a day or two and come back to it during the drafting phases. Seeing it with fresh eyes will be particularly useful when re-considering the structure and placing of paragraphs.
  • Try asking friends to read your draft work. It can be very difficult after repeated reading to see your own mistakes.  Alternatively, use text-speech software such as TextHelp Read&Write (available on the UoN network) to read the text aloud to you.
  • When you have a fairly complete and well-organised draft, revise sentences, with special attention to transitions, checking that a reader will be able to follow the sequences of ideas within and between sentences and between paragraphs.

Points to remember

Check that when you are starting work on your essay and reading materials and sources, make a clear note of the bibliographic details (e.g. author, date, title, publisher etc.) as you will need this information to accurately complete any citation of references and list of sources or bibliography.  Harvard is often used in many schools, but check and follow the recommended system of the School or department offering the module.

Before submission, proofread the final copy checking for grammar and spelling mistakes. You might find it helpful to print out your essay and make notes on the hard copy.

Structuring your essay

Your structure should embody a basic plan necessary to write an essay relevant to the title.

It will need an introduction, a main body and a conclusion (or summing up at the end). However beyond this basic structure, it is likely that your school can provide more detailed guidance.

Introductions

Introductions are like an itinerary or road-map for your reader.  They will usually identify what specific questions or issues you are tackling in the essay (the focus) and indicate how you will work through answering the question/title you are writing about (the method or theory applied). 

It can help to think of the introduction to an essay being around 10% of the total word count.  For a short essay of 1500 words, it may be just a single paragraph of approximately 150 words.  For longer essays, you may need to set the scene of the topic first, so it may be two or three paragraphs in length.

The paragraphs in the main body develop your argument or response to the essay title, using examples to explore the different aspects of the question.  Think about how each paragraph builds up the argument and use connecting words and phrases to link together the paragraphs.  In some departments, you may be encouraged to use headings for the different sections, but check this with your assignment guidelines or tutors. 

Conclusions

The conclusion will indicate the overall themes and summarise the key points you have raised in the essay, identifying how this has addressed the question.  It can help to think of the conclusion as being around 5-10% of the total word count.  For a short essay of 1500 words, it may be a single paragraph of approximately 100-150 words.  For longer essays, the conclusion may be a couple of paragraphs long. The conclusion is where you summarise and synthesize the significance or importance of the key evidence and examples you have discussed.

Remember to not include any new ideas or information in your conclusion.

Proofreading

Many students find it easier to proofread from the printed page rather than a computer screen, but do think about using technology to support your proofreading process.  Text-to-speech software such as TextHelp Read&Write can read text aloud to you, highlighting each word as it reads, and can help identify homophones along with a range of other proofreading support strategies. Read&Write is available on the UoN network. 

  • Check paragraphing for length, transitional links, and internal coherence
  • Check word choice - use a dictionary to check accurate meanings
  • Review your style and check for clarity - reading aloud can often help
  • incomplete sentences
  • missing or mis-used punctuation 
  • possessives (The dog's bone or the two dogs' bone)
  • matching verbs and subjects (plural or singular).
  • Check spelling and typing for possible errors. Run a spell checker, but remember if your mis-spelling actually spells another real word it often won't identify these.

Evaluating your essay

When finishing an essay you should check it against the marking criteria provided by your school. Here are some useful questions to ask yourself:

  • Did you give a brief introduction that provides any indication of the overall flow of your essay?
  • Did you use a logical progression of concepts and information using subheadings, if appropriate, for the main body?
  • Did you include too little information?  You will need detail, or specifics and examples.
  • Did you include too much?  You often don't need more than one or two examples to make a point; you need to make theories, issues or arguments clear, but not verbose. Make sure you keep within the word limit set for the essay.
  • If appropriate to your discipline, did you use clearly labelled diagrams, figures, or images that are referred to in the body of the text? (Diagrams are not free-standing items and are of benefit only when they highlight key points or mechanisms.)
  • Did you write clearly and unambiguously? Keep your sentence construction simple, and avoid overlong sentences. Punctuate correctly.
  • Did you give a brief concluding paragraph to round off your essay?
  • Did you acknowledge your sources using the appropriate referencing system?

Writing a Scientific Paper or Lab Report

Writing a scientific paper is very similar to writing a lab report. The structure of each is primarily the same, but the purpose of each is different

Lab reports are meant to reflect understanding of the material and learn something new Scientific papers are meant to contribute knowledge to a field of study.

Both are generally broken down into eight sections: title, abstract, introduction, methods, results, discussion, conclusion, and references. 

  • Ex: Determining the Free Chlorine Content of Pool Water"
  • Abstracts are a summary of the research as a whole and should familiarize the reader with the purpose of the research. 
  • Abstracts will always be written last, even though they are the first paragraph of a scientific paper. 
  • Unlike a lab report, all scientific papers will have an abstract.
  • Why was the research done?
  • What problem is being addressed?
  • What results were found?
  • What are the meaning of the results?
  • How is the problem better understood now than before, if at all?

Introduction

  • The introduction of a scientific paper discusses the problem being studied and other theory that is relevant to understanding the findings. 
  • The hypothesis of the experiment and the motivation for the research are stated in this section. 
  • Write the introduction in your own words. Try not to copy from a lab manual or other guidelines. Instead, show comprehension of the research by briefly explaining the problem.
  • Methods and Materials
  • Ex: pipette, graduated cylinder, 1.13mg of Na, 0.67mg Ag
  • List the steps taken as they actually happened during the experiment, not as they were supposed to happen. 
  • If written correctly, another researcher should be able to duplicate the experiment and get the same or very similar results. 
  • In a scientific paper, most often the steps taken during the research are discussed more in length and with more detail than they are in lab reports. 
  • The results show the data that was collected or found during the research. 
  • Explain in words the data that was collected.
  • Tables should be labeled numerically, as "Table 1", "Table 2", etc. Other figures should be labeled numerically as "Figure 1", "Figure 2", etc. 
  • Calculations to understand the data can also be presented in the results. 
  • The discussion section is one of the most important parts of a scientific paper. It analyzes the results of the research and is a discussion of the data. 
  • If any results are unexpected, explain why they are unexpected and how they did or did not effect the data obtained. 
  • Analyze the strengths and weaknesses of the design of the research and compare your results to similar research.
  • If there are any experimental errors, analyze them.
  • Explain your results and discuss them using relevant terms and theories.
  • What do the results indicate?
  • What is the significance of the results?
  • Are there any gaps in knowledge?
  • Are there any new questions that have been raised?
  • The conclusion is a summation of the experiment. It should clearly and concisely state what was learned and its importance.
  • If there is future work that needs to be done, it can be explained in the conclusion.
  • When any outside sources to support a claim or explain background information, those sources must be cited in the references section of the lab report. 
  • Scientific papers will always use outside references.

Top tips for writing your first university essay

28 October 2021

Moving from A-level (or equivalent) standard of writing to the expectations required for a degree might seem a little daunting, so to help, UCL student Saumark Bhaumick lists her top tips for writing effective essays.

Hand typing on a laptop

1. Set the standard 

Understanding your academic discipline in relation to your year is the first step to writing a great university essay.  A final-year history essay is going to be very different from a biology essay set for a first-year student.

You should identify what the basic requirements of essays in your field are. This includes common essay structure, tone, and referencing.

If you’re not sure on the answers to these, ask your module tutor for essay examples from previous first year students with similar work from relevant sources. 

2. Understand structuring

Now that you’ve identified what the expectation is for your first essay, you can begin to think about your structure.  To do this, consider what the word limit is. Using essay examples from step 1, allocate a rough percentage for each section in your structure.

For example, you may decide to give 20% of the word count for each main body paragraph, and 10% each to the introduction and conclusion.

3. Plan your essay

At this stage, creating a plan and allocating the appropriate time for each of the stages will really help you. Here’s an example:

  • Research two points for my main argument (3 days)
  • Research two points for my counter argument (3 days)
  • Write the main argument (1 day)
  • Write up the counter argument (1 day)
  • Write my introduction and conclusion (1 day)
  • Referencing and asking someone for feedback (1 day)

4. Research your sources

The research stage will most probably be the most interesting, and the most time-consuming.  Here you should focus on learning and building up your notes, so that when it comes to writing, you can simply reword what you’ve already found.

To do this, know which websites to use for sources (journals, papers etc.) such as UCL Explore , Google Scholar , JSTOR . You can also do this by asking your Module Tutor for recommended sites and databases.

Make sure to read through sources efficiently and track what parts are relevant to your essay question by making your own notes from these sources.

5. Write from your sources and reference correctly

Now you can use the most relevant parts of your research notes to write the essay.

Make sure you don’t copy your notes (created from the sources) word for word! You don’t want to plagiarise for a number of reasons, and UCL’s Turnitin System will find out. 

Add in the sources for each relevant idea to get references. You can reference properly at the end or as you go – both are fine – but make sure you have a rough way to keep track of which sources you’ve used!

Having identified which style of referencing you should use (e.g. Harvard, Vancouver etc.), you can use websites such as Mybib , Citethisforme or Mendeley to easily create a proper, error-free Bibliography and In-text citations.

6. Get feedback 

If you have enough time for this stage, you’ve done well! It would be wise to send your essay draft to your Module Tutor or Personal Tutor and ask for some feedback. 

Nice job! You have written your first university essay. The good news? Every time you write one it gets easier, and you get better!

Writing an Introduction for a Scientific Paper

Dr. michelle harris, dr. janet batzli, biocore.

This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study question , biological rationale, hypothesis , and general approach . If the Introduction is done well, there should be no question in the reader’s mind why and on what basis you have posed a specific hypothesis.

Broad Question : based on an initial observation (e.g., “I see a lot of guppies close to the shore. Do guppies like living in shallow water?”). This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study. Broad questions are not always included in your written text, but are essential for establishing the direction of your research.

Background Information : key issues, concepts, terminology, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies. Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. (e.g., “No studies to date have examined whether guppies do indeed spend more time in shallow water.”)

Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. (e.g., “Do guppies spend different amounts of time in water <1 meter deep as compared to their time in water that is >1 meter deep?”)

Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing. The “BR” provides the logic for your hypothesis and experimental approach, describing the biological mechanism and assumptions that explain why your hypothesis should be true.

The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works. If you have written your biological rationale, your reader should see your hypothesis in your introduction section and say to themselves, “Of course, this hypothesis seems very logical based on the rationale presented.”

  • A thorough rationale defines your assumptions about the system that have not been revealed in scientific literature or from previous systematic observation. These assumptions drive the direction of your specific hypothesis or general predictions.
  • Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful. It may help to think about the rationale as an answer to the questions— how is this investigation related to what we know, what assumptions am I making about what we don’t yet know, AND how will this experiment add to our knowledge? *There may or may not be broader implications for your study; be careful not to overstate these (see note on social justifications below).
  • Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
  • Be open to the possibility that as you work with and think about your data, you may develop a deeper, more accurate understanding of the experimental system. You may find the original rationale needs to be revised to reflect your new, more sophisticated understanding.
  • As you progress through Biocore and upper level biology courses, your rationale should become more focused and matched with the level of study e ., cellular, biochemical, or physiological mechanisms that underlie the rationale. Achieving this type of understanding takes effort, but it will lead to better communication of your science.

***Special note on avoiding social justifications: You should not overemphasize the relevance of your experiment and the possible connections to large-scale processes. Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. Performing an investigation just for the sake of adding to our scientific knowledge (“pure or basic science”) is just as important as applied science. In fact, basic science often provides the foundation for applied studies.

Hypothesis / Predictions : specific prediction(s) that you will test during your experiment. For manipulative experiments, the hypothesis should include the independent variable (what you manipulate), the dependent variable(s) (what you measure), the organism or system , the direction of your results, and comparison to be made.

We hypothesized that reared in warm water will have a greater sexual mating response.

(The dependent variable “sexual response” has not been defined enough to be able to make this hypothesis testable or falsifiable. In addition, no comparison has been specified— greater sexual mating response as compared to what?)

We hypothesized that ) reared in warm water temperatures ranging from 25-28 °C ( ) would produce greater ( ) numbers of male offspring and females carrying haploid egg sacs ( ) than reared in cooler water temperatures of 18-22°C.

If you are doing a systematic observation , your hypothesis presents a variable or set of variables that you predict are important for helping you characterize the system as a whole, or predict differences between components/areas of the system that help you explain how the system functions or changes over time.

We hypothesize that the frequency and extent of algal blooms in Lake Mendota over the last 10 years causes fish kills and imposes a human health risk.

(The variables “frequency and extent of algal blooms,” “fish kills” and “human health risk” have not been defined enough to be able to make this hypothesis testable or falsifiable. How do you measure algal blooms? Although implied, hypothesis should express predicted direction of expected results [ , higher frequency associated with greater kills]. Note that cause and effect cannot be implied without a controlled, manipulative experiment.)

We hypothesize that increasing ( ) cell densities of algae ( ) in Lake Mendota over the last 10 years is correlated with 1. increased numbers of dead fish ( ) washed up on Madison beaches and 2. increased numbers of reported hospital/clinical visits ( .) following full-body exposure to lake water.

Experimental Approach : Briefly gives the reader a general sense of the experiment, the type of data it will yield, and the kind of conclusions you expect to obtain from the data. Do not confuse the experimental approach with the experimental protocol . The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section.

Some Final Tips on Writing an Introduction

  • As you progress through the Biocore sequence, for instance, from organismal level of Biocore 301/302 to the cellular level in Biocore 303/304, we expect the contents of your “Introduction” paragraphs to reflect the level of your coursework and previous writing experience. For example, in Biocore 304 (Cell Biology Lab) biological rationale should draw upon assumptions we are making about cellular and biochemical processes.
  • Be Concise yet Specific: Remember to be concise and only include relevant information given your audience and your experimental design. As you write, keep asking, “Is this necessary information or is this irrelevant detail?” For example, if you are writing a paper claiming that a certain compound is a competitive inhibitor to the enzyme alkaline phosphatase and acts by binding to the active site, you need to explain (briefly) Michaelis-Menton kinetics and the meaning and significance of Km and Vmax. This explanation is not necessary if you are reporting the dependence of enzyme activity on pH because you do not need to measure Km and Vmax to get an estimate of enzyme activity.
  • Another example: if you are writing a paper reporting an increase in Daphnia magna heart rate upon exposure to caffeine you need not describe the reproductive cycle of magna unless it is germane to your results and discussion. Be specific and concrete, especially when making introductory or summary statements.

Where Do You Discuss Pilot Studies? Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.  

from an Intro Ecology Lab:

         Researchers studying global warming predict an increase in average global temperature of 1.3°C in the next 10 years (Seetwo 2003). are small zooplankton that live in freshwater inland lakes. They are filter-feeding crustaceans with a transparent exoskeleton that allows easy observation of heart rate and digestive function. Thomas et al (2001) found that heart rate increases significantly in higher water temperatures are also thought to switch their mode of reproduction from asexual to sexual in response to extreme temperatures. Gender is not mediated by genetics, but by the environment. Therefore, reproduction may be sensitive to increased temperatures resulting from global warming (maybe a question?) and may serve as a good environmental indicator for global climate change.

         In this experiment we hypothesized that reared in warm water will switch from an asexual to a sexual mode of reproduction. In order to prove this hypothesis correct we observed grown in warm and cold water and counted the number of males observed after 10 days.

Comments:

Background information

·       Good to recognize as a model organism from which some general conclusions can be made about the quality of the environment; however no attempt is made to connect increased lake temperatures and gender. Link early on to increase focus.

·       Connection to global warming is too far-reaching. First sentence gives impression that Global Warming is topic for this paper. Changes associated with global warming are not well known and therefore little can be concluded about use of as indicator species.

·       Information about heart rate is unnecessary because heart rate in not being tested in this experiment.

Rationale

·       Rationale is missing; how is this study related to what we know about D. magna survivorship and reproduction as related to water temperature, and how will this experiment contribute to our knowledge of the system?

·       Think about the ecosystem in which this organism lives and the context. Under what conditions would D. magna be in a body of water with elevated temperatures?

Hypothesis

·       Not falsifiable; variables need to be better defined (state temperatures or range tested rather than “warm” or “cold”) and predict direction and magnitude of change in number of males after 10 days.

·       It is unclear what comparison will be made or what the control is

·       What dependent variable will be measured to determine “switch” in mode of reproduction (what criteria are definitive for switch?)

Approach

·       Hypotheses cannot be “proven” correct. They are either supported or rejected.

Introduction

         are small zooplankton found in freshwater inland lakes and are thought to switch their mode of reproduction from asexual to sexual in response to extreme temperatures (Mitchell 1999). Lakes containing have an average summer surface temperature of 20°C (Harper 1995) but may increase by more than 15% when expose to warm water effluent from power plants, paper mills, and chemical industry (Baker et al. 2000). Could an increase in lake temperature caused by industrial thermal pollution affect the survivorship and reproduction of ?

         The sex of is mediated by the environment rather than genetics. Under optimal environmental conditions, populations consist of asexually reproducing females. When the environment shifts may be queued to reproduce sexually resulting in the production of male offspring and females carrying haploid eggs in sacs called ephippia (Mitchell 1999).

         The purpose of this laboratory study is to examine the effects of increased water temperature on survivorship and reproduction. This study will help us characterize the magnitude of environmental change required to induce the onset of the sexual life cycle in . Because are known to be a sensitive environmental indicator species (Baker et al. 2000) and share similar structural and physiological features with many aquatic species, they serve as a good model for examining the effects of increasing water temperature on reproduction in a variety of aquatic invertebrates.

         We hypothesized that populations reared in water temperatures ranging from 24-26 °C would have lower survivorship, higher male/female ratio among the offspring, and more female offspring carrying ephippia as compared with grown in water temperatures of 20-22°C. To test this hypothesis we reared populations in tanks containing water at either 24 +/- 2°C or 20 +/- 2°C. Over 10 days, we monitored survivorship, determined the sex of the offspring, and counted the number of female offspring containing ephippia.

Comments:

Background information

·       Opening paragraph provides good focus immediately. The study organism, gender switching response, and temperature influence are mentioned in the first sentence. Although it does a good job documenting average lake water temperature and changes due to industrial run-off, it fails to make an argument that the 15% increase in lake temperature could be considered “extreme” temperature change.

·       The study question is nicely embedded within relevant, well-cited background information. Alternatively, it could be stated as the first sentence in the introduction, or after all background information has been discussed before the hypothesis.

Rationale

·       Good. Well-defined purpose for study; to examine the degree of environmental change necessary to induce the Daphnia sexual life
cycle.

How will introductions be evaluated? The following is part of the rubric we will be using to evaluate your papers.

 

0 = inadequate

(C, D or F)

1 = adequate

(BC)

2 = good

(B)

3 = very good

(AB)

4 = excellent

(A)

Introduction

BIG PICTURE: Did the Intro convey why experiment was performed and what it was designed to test?

 

Introduction provides little to no relevant information. (This often results in a hypothesis that “comes out of nowhere.”)

Many key components are very weak or missing; those stated are unclear and/or are not stated concisely. Weak/missing components make it difficult to follow the rest of the paper.

e.g., background information is not focused on a specific question and minimal biological rationale is presented such that hypothesis isn’t entirely logical

 

Covers most key components but could be done much more logically, clearly, and/or concisely.

e.g., biological rationale not fully developed but still supports hypothesis. Remaining components are done reasonably well, though there is still room for improvement.

Concisely & clearly covers all but one key component (w/ exception of rationale; see left) clearly covers all key components but could be a little more concise and/or clear.

e.g., has done a reasonably nice job with the Intro but fails to state the approach OR has done a nice job with Intro but has also included some irrelevant background information

 

Clearly, concisely, & logically presents all key components: relevant & correctly cited background information, question, biological rationale, hypothesis, approach.

What are essays?

Most degree programmes include essays. They are the most common form of written assignment and so for most students, being good at essays is essential to gaining good marks, which lead to good grades, which lead to the degree classification desired. Essays are both a particular method of writing and a collection of sub-skills that students need to master during degree studies.

General essay writing

You have an essay to write... what next .

  • Read the assessment brief carefully to find out what the essay is about, what you are required to do specifically. What instructions are you given (discuss, explain, explore)? What choices do you need to make?
  • Work through the practical guide to essays above. This will help you to think about what an essay is and what is required of you.
  • Look at the  assignment writing process . How will you produce your essay?
  • Make a plan for when, where, and how you will research, think, draft, and write your essay.
  • Execute your plan .
  • Finish early. Leave a couple of spare days at the end to  edit and proofread . 
  • Hand it in and move on to the next challenge!

Features of essay writing

Essays vary lots between disciplines and specific tasks, but they share several features that are important to bear in mind. 

  • They are an argument towards a conclusion.  The conclusion can be for or against a position, or just a narrative conclusion. All your writing and argumentation should lead to this conclusion. 
  • They have a reader.  It is essential that you show the logic of your argument and the information it is based on to your reader. 
  • They are based on evidence . You must show this using both your referencing and also through interacting with the ideas and thinking found within the sources you use. 
  • They have a structure.  You need to ensure your structure is logical and that it matches the expectations of your department. You should also ensure that the structure enables the reader to follow your argument easily. 
  • They have a word limit.  1000 words means 'be concise and make decisions about exactly what is important to include' whereas 3500 words means 'write in more depth, and show the reader a more complex and broad range of critical understanding'. 
  • They are part of a discipline/subject area, each of which has conventions . For example, Chemistry requires third person impersonal writing, whereas Women's Studies requires the voice (meaning experiential viewpoint) of the author in the writing. 

Types of essay

Each essay task is different and consequently the information below is not designed to be a substitute for checking the information for your specific essay task. It is essential that you check the assessment brief, module handbook and programme handbook, as well as attend any lectures, seminars and webinars devoted to the essay you are working on.  

Essays in each subject area belong to a faculty (science, social sciences, arts and Humanities). Essays within the same faculty tend to share some features of style, structure, language choice, and scholarly practices. Please click through to the section relevant to your faculty area and if you want to be curious, the other ones too! 

Arts & Humanities essays

Arts and Humanities is a faculty that includes a huge range of subject areas, from Music to Philosophy. Study in the arts and humanities typically focuses on products of the human mind, like music, artistic endeavour, philosophical ideas, and literary productions. This means that essays in the arts and humanities are typically exploring ideas, or interpreting the products of thinking (such as music, art, literature). 

There are a range of essay writing styles in arts and humanities, and each subject area has its own conventions and expectations, which are explained and built into modules within each degree programme. Typically, each essay explores an idea, using critical engagement with source material, to produce an argument.

There is typically more reliance on the interpretation of ideas and evidence by the student than in the sciences and social sciences. For the student, the challenge is to understand and control the ideas in each essay, producing a coherent and logical argument that fulfils the essay brief. As with all essays, careful structure, word choices, and language use are essential to succeeding.

Department-specific advice for essays in Arts and Humanities 

Some departments provide web-based advice:

  • English and Related Literature essay writing advice pages
  • Philosophy essay writing advice pages
  • Music Department 'House Style' guidance for essay writing
  • Language and Linguistic Science style guide

If your department does not appear above, do ask your supervisor or other academic staff what specific guidance is available. 

Key Features of Arts and Humanities essays

  • They are based on evidence . It is important that ideas used in essays are derived from credible and usable sources to root your essay in the scholarly materials of the subject that you are writing about. 
  • There is usually a thesis statement.  This appears towards the end of your introductory paragraph, concisely outlining the purpose and the main argument of the essay. It is short (once sentence), concise, and precise. Though the essay may have multiple sub-arguments, all must tie into the thesis statement. This means it is important to know, state and stick to the primary focus set out in your thesis statement. 
  • They require you to interpret evidence. It is unlikely that you will find a source that directly answers the essay question set. You will typically be required to interpret primary and secondary evidence. Primary evidence includes the manuscript of a novel, or a letter describing an historical event. Secondary evidence includes academic books and peer reviewed articles. 
  • They require you to apply ideas. Many essays will ask you to apply an abstract idea to a scenario, or interpretation of something. For example, you could be asked to apply a Marxist ideology upon Emily Brontë's Wuthering Heights or Post-Colonialist theories upon Shakespeare's The Tempest.
  • Essays vary greatly in terms of length, required depth of thinking and purpose.  You must carefully read the assessment brief and any supporting materials provided to you. It is also important to complete formative tasks that prepare you for an essay, as these will help you to become use to the requirements of the summative essay. 
  • They must show criticality. When interpreting evidence, or applying ideas in your essay you must be aware that there is more than one possible understanding. Through exploring multiple sources and showing the limits and interconnectedness of ideas you show criticality. More information on criticality can be found on the Criticality page of this guide . 

Example extract of an arts and humanities essay

Essay Title: Liturgical expression and national identity during the reign of Æthelred the Unready

This essay is from English studies and shows typical features of an arts and humanities essay. It is examining two ideas, namely 'national identity' and 'liturgical expression' and applying them both to a period of history. The essay does this by analysing linguistic choices, using interpretation from the literature base to create an argument that addresses the essay title. 

It also has the feature of the student using sources of evidence to offer an interpretation that may disagree with some published sources. This use of evidence to create an argument that is novel to the student and requires interpretation of ideas is typical of arts and humanities writing. '"engla God", these liturgical verses themselves both signify and enact a ritualised unity with God.' is an example from the essay extract that shows the careful language choices used to create a concise and precise argument that clearly conveys complex thought to the reader from the author. 

One way of thinking about a good arts and humanities essay is that it is like you are producing a garment from threads. The overall piece has a shape that people can recognise and understand, and each word, like each stitch, builds the whole piece slowly, whilst some key threads, like core ideas in your argument, run through the whole to hold it all together. It is the threading together of the strands of argument that determines the quality of the final essay, just as the threading of strands in a garment determine the quality of the final piece. 

Good arts and humanities essay writing is...

  • Based on evidence sources,
  • built on the interpretation and application of ideas, evidence and theories,
  • a clearly expressed, logical argument that addresses the essay question,
  • carefully constructed to guide the reader in a logical path from the introduction to the conclusion,
  • filled with carefully chosen language to precisely and accurately convey ideas and interpretations to the reader,
  • built on rigorous, careful and close analysis of ideas,
  • constructed using careful evaluation of the significance of each idea and concept used,
  • readable, meaning it is clear and logical, using clearly understandable English,
  • rewarded with high marks.

Common mistakes in arts and humanities essay writing

  • Not answering the question posed. It is very easy to answer the question you wished had been asked, or drift away from the question during your writing. Keep checking back to the question to ensure you are still focussed and make a clear plan before writing.  
  • Moving beyond the evidence. You are required to interpret ideas and evidence that exist, this requires some application and novelty, but should not be making up new ideas/knowledge to make your argument work; your writing must be rooted in evidence. 
  • Using complex and long words where simpler word choices would convey meaning more clearly. Think of the reader. 
  • Leaving the reader to draw their own conclusion s, or requiring the reader to make assumptions. They must be able to see your thinking clearly on the page. 
  • Using lots of direct quotes . There are times when using quotes is important to detail lines from a novel for example, but you need to use them carefully and judiciously, so that most of your writing is based on your use of sources, for which you gain credit.

Social Science essays

Social Sciences, as the name suggests, can be thought of as an attempt to use a 'scientific method' to investigate social phenomena. There is a recognition that applying the strict rules of the level of proof required in science subjects is not appropriate when studying complex social phenomena. But, there is an expectation of as much rigour as is possible to achieve in each investigation.

Consequently, there is a huge variation in the types of essays that can be found within the social sciences. An essay based on the carbon dating of human remains within Archaeology is clearly very different from an essay based on the application of an ethical framework in Human Resources Management. The former is likely to be much more like a science essay, whilst the latter may edge towards a Philosophy essay, which is part of arts and humanities. 

Key features of social science essays

  • They are evidence-based.  It is crucial to use the evidence in a way that shows you understand how significant the evidence used is. 
  • They require interpretation of evidence . By its nature, evidence in social sciences may be less definite than in sciences, and so interpretation is required.  When you interpret evidence, this too must be based on evidence, rather than personal opinion or personal observation. 
  • They often require the application of abstract theories to real-world scenarios . The theories are 'clean and clear' and the real world is 'messy and unclear'; the skill of the student is to make plausible judgements. For example, 
  • The level of detail and breadth of knowledge that must be displayed varies greatly, depending on the length of the essay. 1000 word essays need concise wording and for the student to limit the breadth of knowledge displayed in order to achieve the depth needed for a high mark. Conversely, 5000 word essays require both breadth and depth of knowledge.
  • They should show criticality. This means you need to show uncertainty in the theories and ideas used, and how ideas and theories interact with others. You should present counter-facts and counter-arguments and use the information in the literature base to reach supported conclusions and judgements. 

Example extract of a social science essay

Essay Title: Who Gets What in Education and is that Fair?

Education in the western world has historically favoured men in the regard that women were essentially denied access to it for no other reason than their gender (Trueman,2016) and even though it would seem there is certainly “equality on paper” (Penny, 2010,p1.) when looking at statistics for achievement and gender, the reality is that the struggles facing anyone who does not identify as male require a little more effort to recognise. An excellent example of this can be found in the 2014 OECD report. In the UK women significantly outnumbered men in their application for university places- 376,860 women to 282,170 men (ICEF,2014)- but when observed closer men are applying for places at higher ranking universities and often studying in fields that will eventually allow them to earn better salaries. The same report praised women for the ability to combine their studies with family life and having higher aspirations than boys and therefore likely as being more determined to obtain degrees (ICEF, 2014), yet in reality women have very little choice about coping with the stressful burdens placed on them. The concepts of double burden and triple shift where women are expected to deal with housework and earning an income, or housework, raising children and earning an income (Einhorn, 1993) could in this case relate to the pressure for women to work hard at school to allow them to be able to provide for their families in future. Even women who do not necessarily have their own families or children to care for must face the double burden and triple shift phenomenon in the workplace, as women who work in the higher education sector almost always have the duty of a more pastoral and caring role of their students than male counterparts (Morley,1994).

Education is a social science subject. Some studies within it follow a scientific method of quantitative data collection, whilst others are more qualitative, and others still are more theoretical. In the case of this extract it is about gendered effects in university applications. This is an inevitably complex area to write about, intersecting as it does with social class, economic status, social norms, cultural history, political policy... To name but a few. 

The essay is clearly based on evidence, which in places in numerical and in places is derived from previously written papers, such as 'triple shift where women are expected to deal with housework and earning an income, or housework, raising children and earning an income (Einhorn, 1993)', where the concept of triple shift is derived from the named paper. It is this interleaving of numerical and concrete facts with theoretical ideas that have been created and/or observed that is a typical feature in social sciences. In this case, the author has clearly shown the reader where the information is from and has 'controlled' the ideas to form a narrative that is plausible and evidence-based. 

When compared to science writing, it can appear to be more wordy and this is largely due to the greater degree of interpretation that is required to use and synthesise complex ideas and concepts that have meanings that are more fluid and necessarily less precise than many scientific concepts. 

Good social science essay writing is...

  • filled with clearly articulated thinking from the mind of the author,
  • well structured to guide the reader through the argument or narrative being created,
  • focussed on answering the question or addressing the task presented,
  • filled with carefully chosen evaluative language to tell the reader what is more and less significant,
  • readable - sounds simple, but is difficult to achieve whilst remaining precise,

Common mistakes in social science essay writing 

  • Speculating beyond the limits of the evidence presented . It is important to limit your interpretation to that which is supported by existing evidence. This can be frustrating, but is essential.
  • Using complex words where simpler ones will do. It is tempting to try to appear 'clever' by using 'big words', but in most cases, the simplest form of writing something is clearer. Your aim is to clearly communicate with the reader. 
  • Giving your personal opinion - this is rarely asked for or required. 
  • Not answering the question or fulfilling the task . This is possibly the most common error and largely comes from letting one's own ideas infect the essay writing process. 
  • Not being critical. You need to show the limits of the ideas used, how they interact, counter-arguments and include evaluation and analysis of the ideas involved. If you find yourself being descriptive, ask why. 
  • Using lots of direct quotes, particularly in first year writing . Quotes should be rare and used carefully because they are basically photocopying. Use your words to show you have understood the concepts involved. 

Science essays

Science essays are precise, logical and strictly evidence-based pieces of writing. They employ cautious language to accurately convey the level of certainty within the scientific understanding that is being discussed and are strictly objective. This means that the author has to make the effort to really understand the meaning and significance of the science being discussed.

In a science essay, your aim is to summarise and critically evaluate existing knowledge in the field. If you're doing your own research and data collection, that will be written up in a report  instead.

The skill of the student is to thread together the ideas and facts they have read in a logical order that addresses the task set. When judgements are made they must be justified against the strength and significance of the theories, findings, and ideas being used. Generally, the student should not be undertaking their own interpretation of the results and facts, but instead be using those of others to create a justifiable narrative. 

Example extract of a science essay

Essay title:  To what extent has Ungerleider and Mishkin’s notion of separate ‘what’ and ‘where’ pathways been vindicated by neuropsychological research?

Van Polanen & Davare (2015) showed that the dorsal stream and ventral streams are not strictly independent, but do interact with each other. Interactions between dorsal and ventral streams are important for controlling complex object-oriented hand movements, especially skilled grasp. Anatomical studies have reported the existence of direct connections between dorsal and ventral stream areas. These physiological interconnections appear to gradually more active as the precision demands of the grasp become higher. 

However, cognition is a dynamic process, and a flexible interactive system is required to coordinate and modulate activity across cortical networks to enable the adaptation of processing to meet variable task demands. The clear division of the dorsal and ventral processing streams is artificial, resulting from experimental situations, which do not reflect processing within the natural environment (Weiller et al., 2011). Most successful execution of visual behaviours require the complex collaboration and seamless integration of processing between the two systems.

Cloutman (2013) had stated that dorsal and ventral streams can be functionally connected in three regards: (1) the independent processing account – where they remain separate but terminate on the same brain area, (2) the feedback account – where feedback loops from locations downstream on one pathway is constantly providing input to the other and (3) the continuous cross-talk account – where information is transferred to and from the system constantly when processing. 

Indeed, the authors found that there were numerous anatomical cross-connections between the two pathways, most notably between inferior parietal and inferior temporal areas. For example, ventral regions TE and TEO have been found to have extensive connectivity with dorsal stream areas, demonstrating direct projections with areas including V3A, MT, MST, FST and LIP (Baizer et al., 1991; Disler et al., 1993).

The first obvious comment is that it is not going to win a prize for literary entertainment! The writing is what one might call 'dry'. This is because it is good scientific writing. It is clearly evidence-based, and is explaining complex interrelationships in a way that is clear, leaves little for the reader to assume and that uses carefully graded language to show the significance of each fact. 

The language choices are carefully aligned with the strength of the evidence that is used. For example, 'have been found to have extensive interconnectivity' is graded to convey that many connections have been detailed in the evidence presented. Similarly, 'Most successful execution of visual behaviours require the complex collaboration' is graded carefully to convey meaning to the reader, derived from the evidence used. The sample displays many examples of controlled word choices that leave the reader in no doubt regarding the meaning they are to take from reading the piece. This concise, controlled, evidence-based and carefully considered writing is typical of that found in the science essays. 

Good science essay writing is...

  • evidence-based,
  • cohesive due to language choices,
  • well-structured to help the reader follow the ideas,
  • carefully planned,
  • filled with carefully chosen evaluative and analytical language,
  • rewarded with high grades.

Common mistakes in science essay writing

  • The most common mistake is a lack of accuracy in the language used to convey meaning. This can be due to inadequate reading or a lack of understanding of the subject matter, or alternatively, due to not giving sufficient care to word choice. 'Increased greatly' is different to 'increased', which is different again to 'increased significantly'; it is very important that you understand what you are writing about in enough detail that you can accurately convey an understanding of it accurately to the reader. 
  • Trying to put 'you' into the essay. It is highly unlikely that you will be required to refer to your own viewpoints, opinions or lived experience within scientific essay writing. Science is impersonal, it deals in fact, and so you are a third person, impersonal author who is interpreting and curating facts and knowledge into an essay that makes sense to the reader. 
  • Going beyond the facts. It is rare that you will be asked to speculate in a science essay. When you are, you will be asked to extrapolate from known understanding in the relevant literature. Stick to the facts and to their meaning and significance. 
  • Not placing understanding in context . Each scientific idea sits within a bigger discipline and interacts with other ideas. When you write about ideas, you need to acknowledge this, unless you are specifically told to only focus on one idea. An example would be genomics of viral pathogens, which is currently a much discussed area of activity. This sits within public health, virology, and genomics disciplines, to name a few. Depending on how it is to be written about, you may need to acknowledge one or more of these larger areas. 

Using evidence in essays

Sources of evidence are at the heart of essay writing. You need sources that are both usable and credible, in the specific context of your essay.

A good starting point is often the materials used in the module your essay is attached to. You can then work outwards into the wider field of study as you develop your thinking, and seek to show critical analysis, critical evaluation and critical thought in your essay.

In this section, you will learn about the functions and key components of an essay introduction.

An introduction can fulfill the functions below. These often move from a broad overview of the topic in context to a narrow focus on the scope of the discussion, key terms and organisational structure.

Click on each function to reveal more.

  • It can establish the overall topic and explain the relevance and significance of the essay question to that topic
  • What is the topic?
  • Why is the essay question worth exploring? Why is the essay worth reading?
  • How is it relevant to wider / important / current debates in the field?
  • It can briefly explain the background and context and define the scope of the discussion
  • Is it helpful to mention some background, historical or broader factors to give the reader some context?
  • Is the discussion set in a particular context (geographical; political; economic; social; historical; legal)?
  • Does the essay question set a particular scope or are you going to narrow the scope of the discussion?
  • It can highlight key concepts or ideas
  • Are the key concepts or ideas contentious or open to interpretation?
  • Will the key concepts need to be defined and explained?
  • It can signpost the broad organisational structure of the essay
  • Indicate what you will cover and a brief overview of the structure of your essay
  • points made should be supported by evidence
  • clear links should be made to the question

Note: Introductions may not cover all of these elements, and they may not be covered in this order.

In this activity, you will review and evaluate introductions you have written, identifying areas for improvement.

Find some examples of introductions you have written for essays.

  • Which of the features do they use?
  • Are any elements missing?
  • How might you improve them?

For the following tasks, you will be using an example introduction from one of the following three faculties. Select a faculty to use an introduction from a corresponding subject.

In this activity, you will look at examples of introductions, identifying key features and their purpose.

Here is an example question:

Sociology: Examine some of the factors that influence procrastination in individuals, exploring and evaluating their impact. Identify an area(s) for future research, justifying your choice.

And here is a sample introduction written for this question:

Procrastination is a complex concept which manifests itself in different types of behaviour yet is experienced by individuals universally. A useful definition of procrastination is ‘the voluntary delay of important, necessary, and intended action despite knowing there will be negative consequences for this delay’ (Ferrari and Tice, 2000, Sirois and Pychyl, 2013 cited in Sirois and Giguère, 2018). The influences on procrastination are multi-faceted, which makes their study incredibly challenging. Researchers are now producing a body of work dedicated to procrastination; including meta-analyses such as those by Varvaricheva (2010) and Smith (2015). Influences on procrastination can be considered in two categories, factors with external, environmental, sources and factors with internal sources due to individual differences. However, these external and environmental categories are not completely independent of one another and this essay will seek to explore the complexities of this interdependence. This essay will discuss how different factors influence individual procrastination, by first examining how gender, age and personality affect the procrastination trait under internal factors, before discussing the external factors; how task aversiveness, deadlines and the internet affect procrastination behavioural outcomes. This will be followed by a brief exploration of how the two interact. Finally there a number of gaps in the literature, which suggest avenues for future research.

Nursing: Drawing on your own experiences and understanding gained from the module readings, discuss and evaluate the values, attributes and behaviours of a good nurse.

The Nursing and Midwifery Council’s (NMC) (2015) Code states that a nurse must always put the care of patients first, be open and honest, and be empathic towards patients and their families. Student nurses are expected to demonstrate an understanding of the need for these key skills even at the interview stage and then gain the experiences to develop certain fundamental attributes, values and behaviours in order to advance through the stages of nursing. This assignment will highlight a variety of values, attributes and behaviours a good nurse should have, focusing on courage in particular. Views of courage from political, professional, and social perspectives will be considered, alongside a comparison between the attribute courage and a student nurse’s abilities. This will be demonstrated using observations from practice, appropriate theorists such as Sellman (2011), Lachman (2010) and philosophers including Aristotle and Ross (2011).

Archaeology: Explain some of the ways in which Star Carr has been re-interpreted since the initial discovery in the 1940s. Briefly evaluate how the results of recent excavations further dramatically affect our understanding of this site.

Star Carr has become the ‘best known’ Mesolithic site in Britain (Conneller, 2007, 3), in part because of its high levels of artefact preservation due to waterlogging, as the site was once on the Eastern edge of the ancient Lake Flixton, close to a small peninsula (Taylor, 2007). First excavated by Grahame Clark in 1949-51, there was a further invasive investigation in 1985 and 1989, again in 2006-8, and 2010. An impressive haul of artefacts have been excavated over the years, including bone and antler tools, barbed points, flint tools and microliths, and enigmatic red deer frontlets (Milner et al., 2016). Since Clark’s first published report in 1954 there have been numerous re-examinations of the subject, including by Clark himself in 1974. Resulting interpretations of the site have been much debated; it has been classified as ‘in situ settlement, a refuse dump, and the result of culturally prescribed acts of deposition’ (Taylor et al., 2017). This discussion will explore the ways in which the site has been variously re-interpreted during this time period, and consider how more recent study of the site has prompted new perspectives.

Structuring essay conclusions

In this section you will consider the different functions a conclusion can fulfil, look at examples of conclusions, and identify key features and their purpose.

•  •  •  •  •  •  •  •  • 

A conclusion can fulfil the functions below. These often move from a narrow focus on the outcomes of the discussion to a broad view of the topic's relevance to the wider context.

Summary of the main points in relation to the question

  • This might involve restating the scope of the discussion and clarifying if there any limitations of your discussion or of the evidence provided
  • This may include synthesising the key arguments and weighing up the evidence

Arrive at a judgement or conclusion

  • Having weighed up the evidence, come to a judgement about the strength of the arguments

Restate the relevance or significance of the topic to the wider context

  • Make it clear why your conclusions - which are based on your discussion through the essay - are important or significant in relation to wider/current debates in the field

Make recommendations or indicate the direction for further study, if applicable

  • Recommendations may be for further research or for practice/policy
  • What further research/investigation would be necessary to overcome the limitations above?
  • What are the implications of your findings for policy/practice?

Note: Conclusions may not cover all of these elements, and they may not be covered in this order.

In this task, you will be using an example conclusion from one of the following three faculties. Select a faculty to use a conclusion from a corresponding subject.

And here is a sample conclusion written for the question:

In conclusion procrastination is a complex psychological phenomenon that is influenced by a number of factors, both internal and external. However it has a hugely multifaceted nature and the factors that influence it are not truly independent of one another. Character traits and the environmental impact on behaviour are interrelated; for example similar procrastination outcomes may arise from a highly conscientious individual in a distracting environment and an individual low in conscientiousness in a non-distracting setting. This means that future studies need to be very considered in their approach to separating, or controlling for, these factors. These further studies are important and urgently needed as the impact of procrastination on society is far-reaching. For instance: individuals delay contributing to a pension, meaning that old age may bring poverty for many; couples put off entering into formal contracts with each other, potentially increasing disputes over child custody and inheritance; and indeed women delay starting a family and increasing age leads to decreased fertility, thus leading to higher societal costs of providing assisted fertilisation. Furthermore one could expand the scope to include the effects on children of being born to older parents (such as risks of inherited genetic defects). These are themselves wide fields of study and are mentioned merely to illustrate the importance of further research. Until the nature of influences on procrastination is fully understood, our development of approaches to reduce procrastination is likely to be hindered.

Opportunities for nurses to display courage occur every day, although it is at the nurse’s discretion whether they act courageously or not. As discussed in this assignment, courage is likewise an important attribute for a good nurse to possess and could be the difference between good and bad practice. It is significantly important that nurses speak up about bad practice to minimize potential harm to patients. However nurses do not need to raise concerns in order to be courageous, as nurses must act courageously every day. Professional bodies such as the RCN and NMC recognise that courage is important by highlighting this attribute in the RCN principles. The guidelines for raising concerns unite the attribute courage with the RCN’s principles of nursing practice by improving nurses’ awareness of how to raise concerns. Lachman’s (2010) CODE is an accessible model that modern nurses could use as a strategy to help them when raising concerns. Although students find it difficult to challenge more senior nursing professionals, they could also benefit from learning the acronym to help them as they progress through their career. For nursing students, courage could be seen as a learning development of the ability to confront their fear of personal emotional consequences from participating in what they believe to be the right action. On the whole a range of values, attributes and behaviours are needed in order to be a good nurse, including being caring, honest, compassionate, reliable and professional. These qualities are all important, but courage is an attribute that is widely overlooked for nurses to possess but vitally fundamental.

Star Carr is one of the most fascinating and informative Mesolithic sites in the world. What was once considered to be the occasional winter settlement of a group of hunter-gatherer families, now appears to be a site of year-round settlement occupied over centuries. Since its initial discovery and excavation in the late 1940s and early 1950s, a great deal of further data has been collected, altering interpretations made by the primary excavators who pioneered analysis of the site. What once was considered a typical textbook Mesolithic hunting encampment is now theorized to be a site of ritual importance. The site has produced unique findings such as a multitude of barbed points, twenty one antlered headdresses and the earliest known example of a permanent living structure in Britain. These factors will combine to immortalise the site, even when its potential for further research is thoroughly decayed, which tragically could be very soon (Taylor et al. 2010).

Writing an essay

how to write a scientific essay uni

What is an essay?

An academic essay is a piece of writing in which you present your position on a topic, and support that position by evidence.

An essay has three main parts: introduction, body, and conclusion.

  • In the introduction , you put forward your position (this can take the form of a question or an argument) and its relevance to the chosen topic.
  • In the body of an essay, you support your position through logically connected paragraphs supported by evidence and linked through transitions.
  • In the conclusion , you tell your reader how the points you have made in the body have addressed the question or supported your argument.

10 tips for an excellent essay View

Essay requirements differ across units and faculties, so always read your assignment instructions and marking criteria carefully.

An outline or a mind map will allow you to organise your thoughts and structure the body of the essay in a clear and logical way. Careful planning will help ensure your argument is presented clearly and convincingly.

Make sure your essay has an explicit position or an argument, which is presented in the introduction. This tells the reader what position you are taking in relation to the essay question or prompt.

You must use relevant and reliable evidence (ie. quality academic literature) to support the position or argument you make. You use these to make a set of claims which, together, comprise your argument or position.. This work should be done in the body of the essay.

Make sure you don’t just summarise what you have read, but also compare, contrast, evaluate, and make observations that support your main point.

Ideas need to flow from one to another in a sequence that makes sense to your reader. Follow your plan or adapt it as you go but make sure each paragraph and section flows logically from the one above.

It makes your essay flow better and helps your reader anticipate what’s coming up next.

Each paragraph should develop a single main point, and have a clear topic sentence which makes that point explicit.

Your essay’s conclusion is the last thing that your reader will remember. Make sure you end your essay with a bang - by restating your essay’s overall argument and summarising your main points.

Make sure you leave enough time between drafts to rework your language and ideas. All assignments are dramatically improved by editing and proofreading. Having time for this allows you to see your writing with fresh eyes and makes your editing more effective.

How To Write A Lab Report | Step-by-Step Guide & Examples

Published on May 20, 2021 by Pritha Bhandari . Revised on July 23, 2023.

A lab report conveys the aim, methods, results, and conclusions of a scientific experiment. The main purpose of a lab report is to demonstrate your understanding of the scientific method by performing and evaluating a hands-on lab experiment. This type of assignment is usually shorter than a research paper .

Lab reports are commonly used in science, technology, engineering, and mathematics (STEM) fields. This article focuses on how to structure and write a lab report.

Structuring a lab report, introduction, other interesting articles, frequently asked questions about lab reports.

The sections of a lab report can vary between scientific fields and course requirements, but they usually contain the purpose, methods, and findings of a lab experiment .

Each section of a lab report has its own purpose.

  • Title: expresses the topic of your study
  • Abstract : summarizes your research aims, methods, results, and conclusions
  • Introduction: establishes the context needed to understand the topic
  • Method: describes the materials and procedures used in the experiment
  • Results: reports all descriptive and inferential statistical analyses
  • Discussion: interprets and evaluates results and identifies limitations
  • Conclusion: sums up the main findings of your experiment
  • References: list of all sources cited using a specific style (e.g. APA )
  • Appendices : contains lengthy materials, procedures, tables or figures

Although most lab reports contain these sections, some sections can be omitted or combined with others. For example, some lab reports contain a brief section on research aims instead of an introduction, and a separate conclusion is not always required.

If you’re not sure, it’s best to check your lab report requirements with your instructor.

Your title provides the first impression of your lab report – effective titles communicate the topic and/or the findings of your study in specific terms.

Create a title that directly conveys the main focus or purpose of your study. It doesn’t need to be creative or thought-provoking, but it should be informative.

  • The effects of varying nitrogen levels on tomato plant height.
  • Testing the universality of the McGurk effect.
  • Comparing the viscosity of common liquids found in kitchens.

An abstract condenses a lab report into a brief overview of about 150–300 words. It should provide readers with a compact version of the research aims, the methods and materials used, the main results, and the final conclusion.

Think of it as a way of giving readers a preview of your full lab report. Write the abstract last, in the past tense, after you’ve drafted all the other sections of your report, so you’ll be able to succinctly summarize each section.

To write a lab report abstract, use these guiding questions:

  • What is the wider context of your study?
  • What research question were you trying to answer?
  • How did you perform the experiment?
  • What did your results show?
  • How did you interpret your results?
  • What is the importance of your findings?

Nitrogen is a necessary nutrient for high quality plants. Tomatoes, one of the most consumed fruits worldwide, rely on nitrogen for healthy leaves and stems to grow fruit. This experiment tested whether nitrogen levels affected tomato plant height in a controlled setting. It was expected that higher levels of nitrogen fertilizer would yield taller tomato plants.

Levels of nitrogen fertilizer were varied between three groups of tomato plants. The control group did not receive any nitrogen fertilizer, while one experimental group received low levels of nitrogen fertilizer, and a second experimental group received high levels of nitrogen fertilizer. All plants were grown from seeds, and heights were measured 50 days into the experiment.

The effects of nitrogen levels on plant height were tested between groups using an ANOVA. The plants with the highest level of nitrogen fertilizer were the tallest, while the plants with low levels of nitrogen exceeded the control group plants in height. In line with expectations and previous findings, the effects of nitrogen levels on plant height were statistically significant. This study strengthens the importance of nitrogen for tomato plants.

Your lab report introduction should set the scene for your experiment. One way to write your introduction is with a funnel (an inverted triangle) structure:

  • Start with the broad, general research topic
  • Narrow your topic down your specific study focus
  • End with a clear research question

Begin by providing background information on your research topic and explaining why it’s important in a broad real-world or theoretical context. Describe relevant previous research on your topic and note how your study may confirm it or expand it, or fill a gap in the research field.

This lab experiment builds on previous research from Haque, Paul, and Sarker (2011), who demonstrated that tomato plant yield increased at higher levels of nitrogen. However, the present research focuses on plant height as a growth indicator and uses a lab-controlled setting instead.

Next, go into detail on the theoretical basis for your study and describe any directly relevant laws or equations that you’ll be using. State your main research aims and expectations by outlining your hypotheses .

Based on the importance of nitrogen for tomato plants, the primary hypothesis was that the plants with the high levels of nitrogen would grow the tallest. The secondary hypothesis was that plants with low levels of nitrogen would grow taller than plants with no nitrogen.

Your introduction doesn’t need to be long, but you may need to organize it into a few paragraphs or with subheadings such as “Research Context” or “Research Aims.”

A lab report Method section details the steps you took to gather and analyze data. Give enough detail so that others can follow or evaluate your procedures. Write this section in the past tense. If you need to include any long lists of procedural steps or materials, place them in the Appendices section but refer to them in the text here.

You should describe your experimental design, your subjects, materials, and specific procedures used for data collection and analysis.

Experimental design

Briefly note whether your experiment is a within-subjects  or between-subjects design, and describe how your sample units were assigned to conditions if relevant.

A between-subjects design with three groups of tomato plants was used. The control group did not receive any nitrogen fertilizer. The first experimental group received a low level of nitrogen fertilizer, while the second experimental group received a high level of nitrogen fertilizer.

Describe human subjects in terms of demographic characteristics, and animal or plant subjects in terms of genetic background. Note the total number of subjects as well as the number of subjects per condition or per group. You should also state how you recruited subjects for your study.

List the equipment or materials you used to gather data and state the model names for any specialized equipment.

List of materials

35 Tomato seeds

15 plant pots (15 cm tall)

Light lamps (50,000 lux)

Nitrogen fertilizer

Measuring tape

Describe your experimental settings and conditions in detail. You can provide labelled diagrams or images of the exact set-up necessary for experimental equipment. State how extraneous variables were controlled through restriction or by fixing them at a certain level (e.g., keeping the lab at room temperature).

Light levels were fixed throughout the experiment, and the plants were exposed to 12 hours of light a day. Temperature was restricted to between 23 and 25℃. The pH and carbon levels of the soil were also held constant throughout the experiment as these variables could influence plant height. The plants were grown in rooms free of insects or other pests, and they were spaced out adequately.

Your experimental procedure should describe the exact steps you took to gather data in chronological order. You’ll need to provide enough information so that someone else can replicate your procedure, but you should also be concise. Place detailed information in the appendices where appropriate.

In a lab experiment, you’ll often closely follow a lab manual to gather data. Some instructors will allow you to simply reference the manual and state whether you changed any steps based on practical considerations. Other instructors may want you to rewrite the lab manual procedures as complete sentences in coherent paragraphs, while noting any changes to the steps that you applied in practice.

If you’re performing extensive data analysis, be sure to state your planned analysis methods as well. This includes the types of tests you’ll perform and any programs or software you’ll use for calculations (if relevant).

First, tomato seeds were sown in wooden flats containing soil about 2 cm below the surface. Each seed was kept 3-5 cm apart. The flats were covered to keep the soil moist until germination. The seedlings were removed and transplanted to pots 8 days later, with a maximum of 2 plants to a pot. Each pot was watered once a day to keep the soil moist.

The nitrogen fertilizer treatment was applied to the plant pots 12 days after transplantation. The control group received no treatment, while the first experimental group received a low concentration, and the second experimental group received a high concentration. There were 5 pots in each group, and each plant pot was labelled to indicate the group the plants belonged to.

50 days after the start of the experiment, plant height was measured for all plants. A measuring tape was used to record the length of the plant from ground level to the top of the tallest leaf.

In your results section, you should report the results of any statistical analysis procedures that you undertook. You should clearly state how the results of statistical tests support or refute your initial hypotheses.

The main results to report include:

  • any descriptive statistics
  • statistical test results
  • the significance of the test results
  • estimates of standard error or confidence intervals

The mean heights of the plants in the control group, low nitrogen group, and high nitrogen groups were 20.3, 25.1, and 29.6 cm respectively. A one-way ANOVA was applied to calculate the effect of nitrogen fertilizer level on plant height. The results demonstrated statistically significant ( p = .03) height differences between groups.

Next, post-hoc tests were performed to assess the primary and secondary hypotheses. In support of the primary hypothesis, the high nitrogen group plants were significantly taller than the low nitrogen group and the control group plants. Similarly, the results supported the secondary hypothesis: the low nitrogen plants were taller than the control group plants.

These results can be reported in the text or in tables and figures. Use text for highlighting a few key results, but present large sets of numbers in tables, or show relationships between variables with graphs.

You should also include sample calculations in the Results section for complex experiments. For each sample calculation, provide a brief description of what it does and use clear symbols. Present your raw data in the Appendices section and refer to it to highlight any outliers or trends.

The Discussion section will help demonstrate your understanding of the experimental process and your critical thinking skills.

In this section, you can:

  • Interpret your results
  • Compare your findings with your expectations
  • Identify any sources of experimental error
  • Explain any unexpected results
  • Suggest possible improvements for further studies

Interpreting your results involves clarifying how your results help you answer your main research question. Report whether your results support your hypotheses.

  • Did you measure what you sought out to measure?
  • Were your analysis procedures appropriate for this type of data?

Compare your findings with other research and explain any key differences in findings.

  • Are your results in line with those from previous studies or your classmates’ results? Why or why not?

An effective Discussion section will also highlight the strengths and limitations of a study.

  • Did you have high internal validity or reliability?
  • How did you establish these aspects of your study?

When describing limitations, use specific examples. For example, if random error contributed substantially to the measurements in your study, state the particular sources of error (e.g., imprecise apparatus) and explain ways to improve them.

The results support the hypothesis that nitrogen levels affect plant height, with increasing levels producing taller plants. These statistically significant results are taken together with previous research to support the importance of nitrogen as a nutrient for tomato plant growth.

However, unlike previous studies, this study focused on plant height as an indicator of plant growth in the present experiment. Importantly, plant height may not always reflect plant health or fruit yield, so measuring other indicators would have strengthened the study findings.

Another limitation of the study is the plant height measurement technique, as the measuring tape was not suitable for plants with extreme curvature. Future studies may focus on measuring plant height in different ways.

The main strengths of this study were the controls for extraneous variables, such as pH and carbon levels of the soil. All other factors that could affect plant height were tightly controlled to isolate the effects of nitrogen levels, resulting in high internal validity for this study.

Your conclusion should be the final section of your lab report. Here, you’ll summarize the findings of your experiment, with a brief overview of the strengths and limitations, and implications of your study for further research.

Some lab reports may omit a Conclusion section because it overlaps with the Discussion section, but you should check with your instructor before doing so.

A lab report conveys the aim, methods, results, and conclusions of a scientific experiment . Lab reports are commonly assigned in science, technology, engineering, and mathematics (STEM) fields.

The purpose of a lab report is to demonstrate your understanding of the scientific method with a hands-on lab experiment. Course instructors will often provide you with an experimental design and procedure. Your task is to write up how you actually performed the experiment and evaluate the outcome.

In contrast, a research paper requires you to independently develop an original argument. It involves more in-depth research and interpretation of sources and data.

A lab report is usually shorter than a research paper.

The sections of a lab report can vary between scientific fields and course requirements, but it usually contains the following:

  • Abstract: summarizes your research aims, methods, results, and conclusions
  • References: list of all sources cited using a specific style (e.g. APA)
  • Appendices: contains lengthy materials, procedures, tables or figures

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Written by: Katherine Watson

Starting a literature review can be a daunting task. A literature review is a foundational aspect of a dissertation, but you may also be asked to produce a standalone literature review. You may be unfamiliar with the term literature review, and the first thing to note is that it is not that different to essays you are used to writing….

What is a literature review?

A literature review is a critical summary of existing work on a chosen topic. Importantly, it is not a list or description of ALL texts relevant to your topic. Your literature review should pick up on important ideas, debates, theories, methods and omissions across this body of literature. Rather than repeating or re-wording this information, a literature review represents your own evaluations and comparisons between these texts and should highlight your key take-aways from those readings.

What are the main functions of a literature review?

  • Demonstrate that you have read widely on your topic and have a strong understanding.
  • Recognise existing work.
  • (In the context of a dissertation) Create the foundation for your research and justify the direction, methods and questions you pursue.
  • (In the context of a dissertation) Introduce the background concepts and theories which will underpin your discussion chapter.

Step 1: Gathering literature

  • Key words / search terms. Devise several key words or search terms that encapsulate your research topic.
  • Use online research engines. Input your key words into free online search engines. iFind  by Swansea University is a great place to start. Other options include Google Scholar, ResearchGate, ScienceDirect and Social Science Research Network. There are also discipline specific search engines such as PubMed Central for healthcare and science. There are pros and cons to different search engines in terms of their coverage and accuracy, so it’s worth using at least two to gain access to a fuller range of literature. Be very systematic!
  • Check bibliographies. Utilise the bibliography of relevant journal articles or books to gather even more references. This can be particularly useful for locating older publications which may not be flagged on search engines.
  • Talk to a librarian. Librarians are experts in conducting literature searches. If you are lost about where and how to find literature contact them early and discuss the questions you’re asking, the problem you’re addressing and area you’re working on. They may be able to suggest online databases, journals and books.

Step 2: Organising literature

  • Start collating an accurate record of sources on a Word document or Excel spreadsheet. Be sure to note the title, author(s), and date. You may copy and paste the abstract and key words or write your own summary. However, keep space to add your own evaluation of the literature (see below).
  • Create a logical structure whether that be chronological or thematic. The advantage of creating a table in an Excel spreadsheet is that you can reorder your sources according to when they were published or another criterion.

Step 3: Critical reading

It is important to be selective, you don’t have time to read everything. Tips on how to be a more effective and efficient reader can be found on  Read Right, Write Right.

While the body of literature may be large, you will typically find repetition and common ground between texts. Make a note of these similarities, as well as where approaches or arguments diverge and contrast.

Weed out any sources which are not relevant after your reading and consolidate your list/table of core literature.

Step 4: Critical analysis

This is your opportunity to elaborate on your record of core literature by producing your own summary and reflection of the texts. Return to any notes you’ve written already and re-read relevant sections of the texts if necessary. Don’t just repeat their arguments (though you may note down a small number of quotations). Keep your focal topic at the front of your mind!

The questions listed below can be used as prompts to get you thinking critically:

  • What are the main theories/concepts/methods/approaches being used? How are they justified? What are its key features?
  • Are the conclusions logical and well supported?
  • Does the information fit with what you already know?
  • Does it contradict or dispute other evidence or arguments?
  • Are there gaps or limitations? Has the author overlooked or misunderstood anything?
  • How can you use this in your own work?

As you think, WRITE !  What to do with all of those notes  will help you process your ideas, and these notes will likely find their way into your literature review as your start to write it up formally.

(100 words), honors college applicants, prompt 1, choose a specific connection that you consider interesting or unique; describe and explain the connection and its parts and why that connection is meaningful or significant. you can choose from activities, academic subjects, concepts, natural or human phenomena, etc., write an original essay that clearly and completely addresses the prompt above in 450-500 words in order for your honors college application to be considered. making connections and drawing insights from those connections is a central part of the honors college experience. (450-500 words).

This prompt invites you to explore a specific connection between two or more things that you find interesting or meaningful. Your goal should be to demonstrate your ability to think creatively and across disciplines, and draw insights from seemingly disparate ideas. 

This is also a great opportunity to show off your unique way of looking at the world. The key to a strong response is to not only describe the connection, but also delve into why it’s significant to you.

The broadness of this prompt may seem overwhelming, but take a breath! Here are some questions to help get you thinking about what you might write about. 

  • Have you noticed two areas of your life that are unexpectedly related? Maybe you or someone else was surprised by how similar they are, how one influenced the other, or how lessons learned in one context could be applied to another. 
  • Have you ever connected two concepts that you had previously seen as unrelated? What led you to make this connection? Why does it stand out in your memory as significant?
  • Are there any connections that you have discovered or learned about that shape your understanding of a topic, your community, or even the world? 
  • Is there a connection that is particularly significant to you, your worldview, your values, or goals? 

You can use these questions to generate a list of possible topics. We recommend shooting for 5-10–especially for this kind of nuanced prompt, giving yourself more options means you can compare and contrast them, to determine which is truly the strongest. When you’re ready to narrow down your initial list, think about the following considerations. 

First, your topic should be specific and unique. Talking about how art and science connect is not a strong choice, because art and science are each huge fields, and lots of students see some overlap between them. 

A much stronger choice would be writing about how looking at cells under a microscope gave you a much deeper appreciation for the forms and colors of abstract art. Take advantage of the space given to you – with up to 500 words, you have the room to lay out complex connections. In fact, Oregon State tells you directly that’s exactly what they want you to do!

You’ll also want to pick a connection that you have a personal link to. The point of any college essay is to show the admissions committee more about who you are, not just tell them about something you care about. For the above example, the intersection between microbiology and abstract art could be used to show the author’s attention to detail, love of research, and/or open-mindedness about different art forms.

Finally, you want to hint at how this connection you see will allow you to make positive contributions to the Honors College. Oregon State isn’t expecting you to have the next four years fully planned out, but showing that you’ve already thought about how this aspect of your identity would be an asset to the Honors College community is often the thing that takes an essay from good to great.

This may sound like a lot to keep track of, but if you take your brainstorming seriously, incorporating all of these elements can happen quite naturally. Let’s look at some hypothetical student topics that would make strong responses for this prompt. 

  • A student passionate about both music and math could explore the connection between musical rhythms and mathematical patterns. They might describe how learning about sequences and series helped them conquer a difficult piece, and why they find beauty in the intersection of rhythm and structure. They might talk about how they look forward to using these insights to help make math less intimidating to artistically minded students. 
  • A student interested in environmental science and neuroscience could discuss the relationship between green spaces in cities and mental health. They could explain how their experience volunteering in a community garden taught them to see parks as a key element of public well-being, and how this insight drives their future goals of participating in community gardening at and around Oregon State.
  • A student who loves literature and psychology might write about how reading classic novels helped them understand human behavior. They could describe how analyzing characters’ motivations in books like Crime and Punishment deepened their understanding of moral dilemmas and decision-making processes in real life. Perhaps they plan to start a book club on their floor, so that they can get to know others through their connections to fictional characters. 

As you refine your choice of topic, remember that you’ll need to provide specific examples of your points, so make sure you’ll be able to do so. Note that all of the above examples reference particular moments in the student’s life that illustrate how they first made this connection, and why it became so meaningful to them. 

Describing what learning the piano was like for you is far more effective than just stating “I had always seen math and music as separate fields, but when I learned the piano, that changed.” Instead, you could say something like:

“My fingers flew across the black and white keys, trying desperately to keep up with Tchaikovsky’s Piano Concerto No. 1. For weeks now, every time I started getting close to the third movement, I would make a mistake I couldn’t recover from. As my left hand slipped, that familiar frustration started crackling in my chest. 

But then, in a fraction of a second, my math lesson from the previous day popped into my head: sometimes, a sequence of numbers doesn’t follow the pattern you expect. This time, rather than giving up, I added a quick series of notes which aren’t in the sheet music, but would connect my mistake to the next measure.”

By immersing us fully in this moment alongside them, the student allows us to see exactly how they think, and ensures that they will stand out even from other students who might be exploring a related topic.

Honors College Applicants, Short Response 1

With just 100 words, you’ll need to choose your topics for these next four prompts carefully, to ensure you’re able to clearly communicate what you want to say even in such a short space. To start, this one focuses on your unique interests and creativity, so you’ll want to select a topic that demonstrates your out-of-the-box thinking. 

Your brainstorming for the prompt above could actually come in handy here. Although you don’t want to write about the same thing, as repeating yourself wastes your precious space, you could potentially write about one of the other options you were considering.

Alternatively, you could ask yourself the following questions, to kick off your brainstorming:

  • Examples: Rock climbing, crocheting, Scottish folklore
  • Tracking the popularity of various bird seeds at your birdfeeder, doing a painting on your ceiling that incorporates the stain caused by water damage
  • Training your pet ferret to roll over, analyzing Shakespeare through the lens of immigration

Regardless of which topic you choose, you’ll want to explain what it is quickly, in around twenty words, so that you can spend the bulk of the response explaining what this particular interest says about who you are more broadly. You’ll also want to use specific, anchoring details to make your essay come alive for your readers–describing your creativity in a creative way can take the essay to the next level.

Let’s look at an example of what a strong response might look like. 

“Last summer, fascinated by sustainable architecture, I built a small model home using recycled materials. I researched eco-friendly construction techniques, such as repurposing materials, and implemented those ideas in my model by using worn out dishrags as insulation and plastic bottle caps as roof shingles. I tested my model by leaving it outside in a rainstorm, and was thrilled when not a single drop got through! This project not only deepened my understanding of sustainable practices, but also pushed me to be attentive to detail and see function rather than solely form.”

‌This example is specific in showing the student’s creativity–it doesn’t just mention the recycled model home project, but also gives details about particular materials they repurposed. We can see that they have a deep knowledge of architectural practices and sustainable design, and an appreciation for both the beauty and necessity of building. 

Hopefully, this essay demonstrates that even in just 100 words, you can seamlessly incorporate many elements, to craft a response that makes a genuine impact on your reader.

Honors College Applicants, Short Response 2

To respond to this prompt, you may want to check out our Overcoming Challenges essay breakdown, as this is an example of that archetype. This supplement, however, is only 100 words, so the response will have to be much shorter than your typical Overcoming Challenges essay. As a result, you’ll want to focus on just the most important aspects of this kind of prompt. 

Helpfully, the basic structure your response should take is laid out in the prompt itself: you should describe an important challenge you’ve faced, the way that you handled this problem, and who or what might have helped you through it. Then, you should reflect on how you might have grown or learned about the world and yourself through this process. 

Given the abbreviated length, you should spend around twenty words describing the problem, forty to fifty describing your response and the resources you used, and the last twenty to thirty words reflecting on the broader impact this challenge and resolution had on you. Note that these are just approximations–every response will be different, but if you’re struggling to stay within the count, this is a good blueprint.

Before you start worrying too much about length, though, here are some guiding questions to help you come up with an appropriate problem to write about.

  • Have you faced a challenge where you had to rely on external support or resources to work through it?
  • Have you dealt with a challenge that changed your perspective or worldview?
  • Are there any obstacles you’re particularly proud of having gotten past? 
  • What adverse circumstances have taught you the most about yourself?

Make sure to pick something that you can effectively unpack in 100 words. This is a very short response, so you probably won’t be able to do justice to a long and involved story, even if it was deeply meaningful to you. You still want to pick something significant to you, of course–if you don’t really care about this problem, the admissions committee won’t either–but the problem should be relatively straightforward.

That said, you want to avoid cliché topics like moving to a new place, suffering a sports injury, or working through a difficult class. While you don’t need to find something that admissions officers have absolutely never seen before, as that’s practically impossible, there are some topics that are just too overused.

Here are some examples of experiences that could work well:

  • Doing a major group project where the members all had different ideas about what your final presentation should look like, so you organized a meeting with your teacher so she could help you find a middle ground
  • Spilling water on your final painting for an art class, and brainstorming ideas with your classmates about how to incorporate the huge blotch into the piece
  • Tutoring at an elementary school where many students don’t speak English, and reaching out to language instructors at your local university to learn how to use image-based instructional methods

If your story is not as unique as you might like, that’s okay. Try to find an angle that’s particular to you, or reflect on the experience in a way that demonstrates your unique worldview, values, and personality. There’s no one way to stand out from the crowd, but you want to make sure you incorporate something that shows admissions officers what you have to offer that nobody else does.

After selecting your story, try to pick a few key details to make your account compelling and anchored in something real. You don’t have a ton of room, but even saying something like “The hallway rang with a mix of languages, from Spanish to Korean to Arabic,” rather than “When I arrived at the school, I heard a lot of different languages,” goes a long way.

Honors College Applicants, Short Response 3

‌This prompt asks you to reflect on your personal experiences, beliefs, and values, and explain how you will actively contribute to making OSU more inclusive. To get started, you’ll want to identify a moment or experience where you actively worked towards inclusivity, to demonstrate your personal investment in diversity.

To brainstorm, consider when diverse experiences, identities, or perspectives have made a difference in your own life, or in the lives of those close to you. You don’t have to have created the environment that made this mingling possible yourself, so long as you still learned what a positive diverse environment looks like, and took away lessons that you could bring to Oregon State with you.

While describing past experiences is important, you want to do that relatively quickly, as the real key to this essay is explaining how you will work to embrace diversity on Oregon State’s campus. You’ll want to reflect on what your past experiences taught you about how to make a community more inclusive, and how you plan to put those lessons into action. As always, specificity is crucial, to show that diversity is a genuine value of yours.

Let’s look at some hypothetical examples of what a strong response might include. 

  • A student with a foster sibling might write about their efforts to change the language teachers and administrators at their school used around families and parents, and how they hope to start a club or movement on campus around awareness and celebration of nontraditional families. 
  • A computer science student passionate about the outdoors might talk about how through coding classes at OSU, they hope to create an app to upload accessibility descriptions to trail maps, to make hiking more accessible to those with disabilities. 
  • A student interested in neuroscience might write about how they can’t wait to join clubs and initiatives focused on mental health and lead outreach efforts to struggling students, because in high school they volunteered for a crisis hotline, which taught them that people with mental illnesses must be involved in designing the support systems that are supposed to help them. 
  • A student from a rural area might talk about how being from a small town allowed them to get involved in local government even while still in high school, and how they hope to join OSU’s student government and host informal activities like barbeques to encourage all students to have a voice in what happens at the school.

Each of these students has a specific vision for how they will show up for underrepresented students at Oregon State. Even if you haven’t had a chance to do activism work in high school, or don’t have a super specific plan for what you hope to do in college yet, that’s okay–just write about a past experience that taught you about diversity, and how those lessons will guide your future on Oregon State’s campus.

Honors College Applicants, Short Response 4

Here, the qualities you want to demonstrate are your capacity for hard work, dedication, and attention to detail. You’ll also want to showcase a goal you’ve set yourself, to show how those qualities are going to help you grow and develop in college.

First, you’ll want to pick a clear, focused goal. Something like “become a better writer” is a worthy goal, but it’s also one where measuring progress is hard, and one without a clear point at which you could say you’ve “accomplished” it.

Reading the classics for a better understanding of technique, writing 500 words every day for a month, or submitting a piece of work for publication are more specific ways of articulating the same idea as this vague goal.

Your goal should also be relatively ambitious. Choosing something like getting better at chores, or achieving a high score in a video game, may not be taken seriously by an admissions committee. On the other hand, choosing something drastic, like becoming the president of the United States or winning a Nobel Peace Prize, will also come across as disingenuous, so make sure you aim for the middle ground.

The best essay will focus on a goal that is achievable, but also demonstrates that you have confidence and self-motivation, and are eager to employ those traits in service of what matters most to you. You should also be able to cite concrete steps you’ve already taken that prove you’re currently working towards your goal. Your essay might even show grit and perseverance if you’ve overcome setbacks or worked through hardship in pursuit of your goal.

Covering all these bases might sound overwhelming, so let’s look at an example of an essay that puts all these things together. 

“Growing up without much money didn’t just mean going without the 64 pack of crayons. It meant that when I came home after school, my parents were too busy to help me with homework. As a high schooler, I wanted to give others the support I hadn’t had, so I co-founded a free tutoring program at the library for low-income students. Managing volunteers and developing lesson plans while doing my own work has required strong organization skills and the sacrifice of free time, but my efforts have helped over 30 students improve their grades, which is more than worth it.”

This student clearly tells us about how their background shapes their goals: feeling lost academically inspired them to help prevent others from feeling that way. They then explain a step they’ve already taken–starting a tutoring program–that shows they’re willing to put their money where their mouth is, so to speak. They come across as empathetic, altruistic, and genuinely appreciative of education and the opportunities it provides, and they also clearly place a high value on equity.

Whatever story you tell, choose something that showcases your best qualities, your capacity for growth and reflection, and, of course, your readiness to work hard to achieve your dreams.
