WRITING A SCIENTIFIC RESEARCH ARTICLE
| Format for the paper | Edit your paper! | Useful books |FORMAT FOR THE PAPER
Scientific research articles provide a method for scientists to communicate with other scientists about the results of their research. A standard format is used for these articles, in which the author presents the research in an orderly, logical manner. This doesn't necessarily reflect the order in which you did or thought about the work. This format is:
| Title | Authors | Introduction | Materials and Methods | Results (with Tables and Figures) | Discussion | Acknowledgments | Literature Cited |
- Make your title specific enough to describe the contents of the paper, but not so technical that only specialists will understand. The title should be appropriate for the intended audience.
- The title usually describes the subject matter of the article: Effect of Smoking on Academic Performance"
- Sometimes a title that summarizes the results is more effective: Students Who Smoke Get Lower Grades"
1. The person who did the work and wrote the paper is generally listed as the first author of a research paper.
2. For published articles, other people who made substantial contributions to the work are also listed as authors. Ask your mentor's permission before including his/her name as co-author.ABSTRACT
1. An abstract, or summary, is published together with a research article, giving the reader a "preview" of what's to come. Such abstracts may also be published separately in bibliographical sources, such as Biologic al Abstracts. They allow other scientists to quickly scan the large scientific literature, and decide which articles they want to read in depth. The abstract should be a little less technical than the article itself; you don't want to dissuade your potent ial audience from reading your paper.
2. Your abstract should be one paragraph, of 100-250 words, which summarizes the purpose, methods, results and conclusions of the paper.
3. It is not easy to include all this information in just a few words. Start by writing a summary that includes whatever you think is important, and then gradually prune it down to size by removing unnecessary words, while still retaini ng the necessary concepts.
3. Don't use abbreviations or citations in the abstract. It should be able to stand alone without any footnotes.INTRODUCTION
What question did you ask in your experiment? Why is it interesting? The introduction summarizes the relevant literature so that the reader will understand why you were interested in the question you asked. One to fo ur paragraphs should be enough. End with a sentence explaining the specific question you asked in this experiment.MATERIALS AND METHODS
1. How did you answer this question? There should be enough information here to allow another scientist to repeat your experiment. Look at other papers that have been published in your field to get some idea of what is included in this section.
2. If you had a complicated protocol, it may helpful to include a diagram, table or flowchart to explain the methods you used.
3. Do not put results in this section. You may, however, include preliminary results that were used to design the main experiment that you are reporting on. ("In a preliminary study, I observed the owls for one week, and found that 73 % of their locomotor activity occurred during the night, and so I conducted all subsequent experiments between 11 pm and 6 am.")
4. Mention relevant ethical considerations. If you used human subjects, did they consent to participate. If you used animals, what measures did you take to minimize pain?RESULTS
1. This is where you present the results you've gotten. Use graphs and tables if appropriate, but also summarize your main findings in the text. Do NOT discuss the results or speculate as to why something happened; t hat goes in th e Discussion.
2. You don't necessarily have to include all the data you've gotten during the semester. This isn't a diary.
3. Use appropriate methods of showing data. Don't try to manipulate the data to make it look like you did more than you actually did.
"The drug cured 1/3 of the infected mice, another 1/3 were not affected, and the third mouse got away."TABLES AND GRAPHS
1. If you present your data in a table or graph, include a title describing what's in the table ("Enzyme activity at various temperatures", not "My results".) For graphs, you should also label the x and y axes.
2. Don't use a table or graph just to be "fancy". If you can summarize the information in one sentence, then a table or graph is not necessary.DISCUSSION
1. Highlight the most significant results, but don't just repeat what you've written in the Results section. How do these results relate to the original question? Do the data support your hypothesis? Are your results consistent with what other investigators have reported? If your results were unexpected, try to explain why. Is there another way to interpret your results? What further research would be necessary to answer the questions raised by your results? How do y our results fit into the big picture?
2. End with a one-sentence summary of your conclusion, emphasizing why it is relevant.ACKNOWLEDGMENTS
This section is optional. You can thank those who either helped with the experiments, or made other important contributions, such as discussing the protocol, commenting on the manuscript, or buying you pizza.REFERENCES (LITERATURE CITED)
There are several possible ways to organize this section. Here is one commonly used way:
1. In the text, cite the literature in the appropriate places:
Scarlet (1990) thought that the gene was present only in yeast, but it has since been identified in the platypus (Indigo and Mauve, 1994) and wombat (Magenta, et al., 1995).
2. In the References section list citations in alphabetical order.
Indigo, A. C., and Mauve, B. E. 1994. Queer place for qwerty: gene isolation from the platypus. Science 275, 1213-1214.
Magenta, S. T., Sepia, X., and Turquoise, U. 1995. Wombat genetics. In: Widiculous Wombats, Violet, Q., ed. New York: Columbia University Press. p 123-145.
Scarlet, S.L. 1990. Isolation of qwerty gene from S. cerevisae. Journal of Unusual Results 36, 26-31.
EDIT YOUR PAPER!!!
"In my writing, I average about ten pages a day. Unfortunately, they're all the same page."
A major part of any writing assignment consists of re-writing.
- Scientific writing must be accurate. Although writing instructors may tell you not to use the same word twice in a sentence, it's okay for scientific writing, which must be accurate. (A student who tried not to repeat the word "hamster" produced this confusing sentence: "When I put the hamster in a cage with the other animals, the little mammals began to play.")
- Make sure you say what you mean.
- Be careful with commonly confused words:
Instead of: The rats were injected with the drug. (sounds like a syringe was filled with drug and ground-up rats and both were injected together)
Write: I injected the drug into the rat.
Temperature has an effect on the reaction.
Temperature affects the reaction.
I used solutions in various concentrations. (The solutions were 5 mg/ml, 10 mg/ml, and 15 mg/ml)
I used solutions in varying concentrations. (The concentrations I used changed; sometimes they were 5 mg/ml, other times they were 15 mg/ml.)
Less food (can't count numbers of food)
Fewer animals (can count numbers of animals)
A large amount of food (can't count them)
A large number of animals (can count them)
The erythrocytes, which are in the blood, contain hemoglobin.
The erythrocytes that are in the blood contain hemoglobin. (Wrong. This sentence implies that there are erythrocytes elsewhere that don't contain hemoglobin.)
1. Write at a level that's appropriate for your audience.
"Like a pigeon, something to admire as long as it isn't over your head." Anonymous
2. Use the active voice. It's clearer and more concise than the passive voice.
Instead of: An increased appetite was manifested by the rats and an increase in body weight was measured.
Write: The rats ate more and gained weight.
3. Use the first person.
Instead of: It is thought
Write: I think
Instead of: The samples were analyzed
Write: I analyzed the samples
4. Avoid dangling participles.
"After incubating at 30 degrees C, we examined the petri plates." (You must've been pretty warm in there.)
1. Use verbs instead of abstract nouns
Instead of: take into consideration
2. Use strong verbs instead of "to be"
Instead of: The enzyme was found to be the active agent in catalyzing...
Write: The enzyme catalyzed...
3. Use short words.
"I would never use a long word where a short one would answer the purpose. I know there are professors in this country who 'ligate' arteries. Other surgeons tie them, and it stops the bleeding just as well."
have sufficient enough utilize use demonstrate show assistance help terminate end
4. Use concise terms.
Instead of: Write: prior to before due to the fact that because in a considerable number of cases often the vast majority of most during the time that when in close proximity to near it has long been known that I'm too lazy to look up the reference
5. Use short sentences. A sentence made of more than 40 words should probably be rewritten as two sentences.
"The conjunction 'and' commonly serves to indicate that the writer's mind still functions even when no signs of the phenomenon are noticeable." Rudolf Virchow, 1928
Check your grammar, spelling and punctuation
1. Use a spellchecker, but be aware that they don't catch all mistakes.
"When we consider the animal as a hole,..." Student's paper
2. Your spellchecker may not recognize scientific terms. For the correct spelling, try Biotech's Life Science Dictionary or one of the technical dictionaries on the reference shelf in the Biology or Health Sciences libraries.
3. Don't, use, unnecessary, commas.
4. Proofread carefully to see if you any words out.

Regardless of the nature of your research, if you are writing a paper an outline will help you to not only organize your thoughts, it will also serve as the template for your entire paper. An outline for a research paper is a visual reminder to include all of the pertinent details of your research into your essay or paper. It is essentially a skeletal version of the true paper, and will guide you through the entire process.
Initially, separating your essay, research or other paper into various components (Introduction, Body, Conclusion, etc.) will help you to stay better organized and reduce the risk of important information being forgotten or unintentionally omitted. Furthermore, breaking the essay down into these parts will allow you to address specific parts individually and lessen the chances of feeling overwhelmed or like you might be in over your head.
The structure of your outline will be similar regardless of whether you are writing a scientific paper or something more general. Interestingly, the structure of a research outline is nearly identical to that of a research paper template. In order to better acquaint yourself with the structure of an outline, check out sample research papers online. The USC Guide to Making an Outline will also help you.
Relatively straightforward, right? However, the part to remember is that each part serves a specific purpose and how you arrange information in your outline will drive how your paper reads upon completion.
The Introduction is one of the most important elements of any great research paper, and interestingly enough, often written LAST. This is because the purpose of the introduction is to grab the attention of the reader, this is done by presenting the reader with the topic, and using the thesis statement as an opportunity to ‘hook’ the attention of the reader.
The Body is the heartiest part of the essay, it includes many fact-rich paragraphs or subsections and will allow you to build upon your thesis statement by providing facts to support your argument. This section should not only elaborate on your opening statement, but also provide insight into the methods used to conduct your research and also include investigative points or answers to questions pondered.
You will also want to consider using a literature overview. This is achieved by documenting the literary sources used to support your theories and hypothesis. The topic of your paper and the selected literature should be adjacent.
If you used any sort of data validation, this will typically follow the methodology and literature sections. This is where you will highlight your results and mention other variables that you’ve uncovered in your research. You might choose to use graphs or tables, but remember to explain these to your readers.
Lastly, you will write your Conclusion. The conclusion typically does not offer new information, but rather summarizes the main points addressed in the paper. It is mandatory to also reiterate the thesis statement and mention any future research.
There are a number of sources you can turn to for research paper examples and, depending on your field of study, a plethora of potential high quality topics exist to pull your subject matter from.
As you will learn from looking any good research paper example, writing a great paper involves so much more than simply throwing a bunch of text and citations into a word processor and hoping for the best.
A passing grade means not only thoroughly researching your topic and ensuring that all of your sources are accurately cited, it also means ensuring that your research essay is properly formatted. The following guideline will help you to create finished paper that not only reads like it was professionally written – but also looks like it!
Use clean, good quality 8 1/2″ x 11″ white paper, one side only.
Leave margins of your essay 1″ (2.5 cm) at the top, bottom, left and right sides of each and every page. 1″ is about 10 typed spaces. Exception is made for page numbers which are placed 1/2″ (1.25 cm) from the top upper-right hand corner, flushed to the right margin.
3. Title Page
A title page is not essential for a research paper unless specifically requested by your teacher. The MLA Handbook provides a general guideline on writing a research paper and documenting sources. In case of conflict, you should always follow guidelines set down by your teacher.
If you don’t have a title page, you may begin 1″ from the top of the first page of your essay and start typing your name flushed against the left margin. Then under your name, on separate lines, double-spaced, and flushed against the left margin, type your teacher’s name, your course code, and the date.
If your teacher prefers the first page of your essay not be numbered, you will begin numbering with page 2.
Double-space after the date. On a new line, center the title of your essay. If you have a long title, double-space between lines of the title.

Gun Control: Pros and Cons
Do not type your title all in capital letters. Do not put quotations marks before and after the title. Do not underline the title, or put a period at the end of the title. Proper names of people and places as well as important words should be capitalized in the title, but prepositions and conjunctions are normally shown in lower case letters, e.g. Harry Potter and the Chamber of Secrets. The same rule applies to headings and subheadings as well.
Follow the same capitalization rules for acronyms as you normally would in writing a text of the essay, e.g. FBI would be all in capitals as it is the acronym for Federal Bureau of Investigations. When using an acronym, especially an uncommon one, you must indicate what the letters stand for at the first occurrence in your essay. Example: The North American Aerospace Defense Command (NORAD) is nearly finished converting from using standard desktop PCs to blade PCs.
If a Title Page is a requirement for your assignment, begin on a new page. Use a format preferred by your teacher. Otherwise, center each line and double-space every line on a blank page: name of school (optional), title of paper in upper and lower case, course code, course name (optional), teacher’s name, your first and last name, and date.
Your separate title page should appear as follows:
Gun Control: Pros and Cons
Ms. K. Smith
16 January 2006
The following example shows what NOT to do for a title page:
TITLE OF ESSAY: “GUN CONTROL: PROS AND CONS”
COURSE CODE: “NRW-3A1-01”
TO MY TEACHER: “MS. KATIE ELIZABETH SMITH”
FROM YOUR STUDENT: “TRACY MARIA CHRISTINA CARMELA JONES”
ASSIGNMENT DUE DATE: “MONDAY, JANUARY THE SIXTEENTH, IN THE YEAR 2006”
It is not necessary to describe or explain the title page by adding the words: Title, Course Code, To, From, or Due Date. More is not better. Minimal information providing simple identification is adequate.
4. Numbering Pages and Paragraphs
Number your pages consecutively throughout the essay in the upper right hand corner, flush against the right margin and 1/2″ from the top. The MLA Handbook recommends that you type your last name just before the page number in case the pages get misplaced (134). On page 4 of your essay, for example, your top right-hand corner should show: Jones 4
Page numbers must be written in Arabic numerals. Do not add anything fancy to decorate a page number. Do not underline it, enclose it between hyphens, parentheses, asterisks, or precede it with “Page”, “Pg.”, “P.”, or add a period after the number. In other words, DO NOT use any of the following:
PAGE 4, Page 4, Pg. 4, P 4, pg. 4, p. 4, #4, ~ 4 ~, – 4 -, * 4*, (4), “4”, 4, or 4.
Simply write: 4
Remember, there is no period after the page number.
If you are submitting your essay to your teacher via e-mail, he or she may prefer that you number all your paragraphs consecutively with reference points by adding  at the beginning of your 1st paragraph,  before your 2nd paragraph, and so forth. Electronic submission of documents is becoming more common as e-mail is being used widely. This system will facilitate the citation of sources by identifying a specific paragraph for reference very quickly.
5. Spacing Between Lines
Whether your essay is handwritten, typed or printed, the entire essay should be double-spaced between lines along with 1″ margin on all sides for your teacher to write comments.
Spacing Between Words
In general, leave one space between words and one space after every comma, semi-colon, or colon. Traditionally, two spaces are required at the end of every sentence whether the sentence ends with a period, a question mark, or an exclamation mark. Although it is not wrong to leave two spaces after a period, it is quite acceptable nowadays to leave only one space after each punctuation mark. However, NO space should be left in front of a punctuation mark; for example, the following would be incorrect: op. cit. or “Why me?”
For details on how to place tables, illustrations, figures, musical notations, labels, captions, etc. in your essay, please see the MLA Handbook (134-137).
If a handwritten essay is acceptable to your teacher, remember to double-space all lines, and begin each paragraph with an indentation of 1″ from the left margin. Use the width of your thumb as a rough guide.
If you are using a typewriter or a word processor on a computer, indent 5 spaces or 1/2″ at the beginning of each paragraph. Indent set-off quotations 10 spaces or 1″ from the left margin.
Your instructor may give you a choice to indent or not to indent your paragraphs. No matter whichever one you choose to use, you must be consistent throughout your essay.
If you are NOT indenting, you will start each paragraph flush to the left margin. It is essential that you double-space between lines and quadruple-space between paragraphs. When paragraphs are not indented, it is difficult for a reader to see where a new paragraph begins, hence quadruple-space is called for between paragraphs. Set-off quotations should still be indented 10 spaces or 1″ from the left margin.
7. Right Justify and Automatic Hyphens:
Do not right justify your entire essay and do not automatically format hyphens if you are using a word processor to type your essay. Left justify or justify your essay and type in the hyphens yourself where needed. Left justification is preferred as it will not leave big gaps between words.
8. Titles of Books, Magazines, Newspapers, or Journals
When used within the text of your paper, titles of all full-length works such as novels, plays, or books, should be underlined, e.g. Shakespeare’s Theater.
Put in quotation marks titles of shorter works, such as newspaper, journal, and magazine articles, chapters of books or essays, e.g.: “Giving Back to the Earth: Western Helps Make a Difference in India.”
For all title citations, every word, except articles (“a”, “an”, “the”), prepositions (such as “in”, “on”, “under”, “over”), and conjunctions (such as “and”, “because”, “but”, “however”), should be capitalized, unless they occur at the beginning of the title or subtitle, e.g.: “And Now for Something Completely Different: A Hedgehog Hospital.”
Look it up in a dictionary whenever you are not sure whether a word is being used as a preposition, a conjunction, a noun, a verb, or an adverb. The word “near”, for instance, may be an adverb, an adjective, a verb, or a preposition depending on the context in which it is used.
For complicated details on how to cite titles and quotations within titles, sacred texts, shortened titles, exceptions to the rule, etc. please consult the MLA Handbook (102-109).
9. Writing an Essay All in Capital Letters:
DO NOT WRITE OR TYPE EVERYTHING ALL IN CAPITAL LETTERS EVEN THOUGH THIS SAVES YOU TIME AND EFFORT NOT TO HAVE TO USE THE SHIFT KEY REPEATEDLY OR TO HAVE TO FIGURE OUT WHEN OR WHEN NOT TO USE CAPITAL LETTERS.SOME PEOPLE WRITE EVERYTHING IN CAPITAL LETTERS BECAUSE THEY HAD NEVER LEARNED TO WRITE SENTENCES IN UPPER AND LOWER-CASE LETTERS PROPERLY WHEN THEY WERE IN ELEMENTARY SCHOOL.OTHER PEOPLE WRITE ALL IN CAPITAL LETTERS BECAUSE THEY WANT TO MAKE WHAT THEY WRITE APPEAR IMPORTANT.READING A PAPER ALL WRITTEN IN CAPITAL LETTERS,ESPECIALLY ONE WITHOUT SPACES AFTER PUNCTUATION MARKS,SLOWS DOWN READING SPEED AND MAY EVEN REDUCE READER COMPREHENSION,BESIDES BEING EXTREMELY ANNOYING TO THE READER.REMEMBER THAT THE PURPOSE OF WRITING ANYTHING IS TO COMMUNICATE.MOST OF US ARE NOT CONDITIONED TO READ ALL TEXT IN CAPITAL LETTERS.WORD PROCESSORS ALSO TREAT WORDS STUCK TOGETHER WITHOUT SPACES AS SINGLE WORDS CAUSING OTHER PROBLEMS.
10. Table of Contents
A short essay or research paper requires no Table of Contents.
If your written report or research paper is extremely long, it may be helpful to include a Table of Contents showing the page number where each section begins.
For those writing a lengthy document, i.e. a book, here is the suggested order for placing items in a Table of Contents:
Acknowledgements, Foreword, Introduction, Body (Parts I, II, III), Summary or Conclusion, Afterword, Explanatory Notes, Appendices, Contact Organizations, Glossary, Endnotes (if not using Footnotes or Parenthetical citations), Bibliography, Index.
A less involved Table of Contents may include simply the following sections: Introduction, Body (use main section headings), Conclusion (or Summary), Works Cited (or References), along with the corresponding page number where each section begins.
Introduction ………………………………………………………………… 1
Government ………………………………………………………………… 3
Economy ……………………………………………………………………… 6
Arts and Entertainment ……………………………………………….. 10
Conclusion ………………………………………………………………….. 14
Works Cited ………………………………………………………………… 15
11. End of Essay
No special word, phrase or fancy symbol is needed to mark the end of your essay. A period at the end of your last sentence is all that is needed.
12. Keeping Essay Together
Sheets of paper should be stapled at the upper left-hand corner. Use a paper clip if no stapler is available. Do not use a pin or fold the paper. Unless specifically requested by your teacher, do not hand in your paper in a folder, a binder, a plastic jacket, rolled up with an elastic band around it, or tied with a ribbon or a string. Do not spray perfume or cologne on your paper or use scented paper. And NEVER hand in your research or term paper in loose sheets even if the sheets are numbered and neatly placed in an envelope or folder.
The condition of the paper you hand in is an indication of the respect you have for yourself and the respect you have for your teacher. Before handing in your paper, ask yourself, “Is this the VERY BEST that I can do?”
Final Note on Your Essay
The topics used for each research paper are inherently different, and even identical topics will appear to be unique based on the viewpoints and educational level of the author. Regardless of your grade level or the topic you’ve been assigned, a research paper outline can help you turn in a great essay. It should include a bulleted list of subheadings and headings, be sure to include as much detail as possible. Crossing out each section as you finish it will help you to stay thorough.
Here is a sample research paper outline.
- A quick overview or introduction of the topic or issue
- The methodology being used
- The thesis statement
- A full review of every source used and all of the corresponding literature
- A brief explanation of the relevance of the research
- Detailed and thorough information about the main points of the argument
- Use as many paragraphs as necessary. Each paragraph should represent a different point.
- Brief summary of all of the main points or facts mentioned in the body.
- Reiteration of the thesis statement
- Closing remark or thought.
