How To Write An Abstract For A Lab Report: 7 Tips


Readers of this handout may also find our handout on writing in the sciences useful. You did an experiment or study for your science class, and now you have to write it up for your teacher to review. You feel that you understood the background sufficiently, designed and completed the study effectively, obtained useful data, and can use those data to draw conclusions about a scientific process or principle.

But how exactly do you write all that? What is your teacher expecting to see? To take some of the guesswork out of answering these questions, try to think beyond the classroom setting. In fact, you and your teacher are both part of a scientific community, and the people who participate in this community tend to share the same values. As long as you understand and respect these values, your writing will likely meet the expectations of your audience—including your teacher.

So why are you writing this research report? Generally speaking, people investigating some scientific hypothesis have a responsibility to the rest of the scientific world to report their findings, particularly if these findings add to or write a lab report previous write a lab report. The people reading such reports have two primary goals:.

Good question. Here is the basic format scientists have designed for research reports:. Overall, however, the IMRAD format was devised to represent a textual version of the scientific method. In essence, the format for a research report in the sciences mirrors the scientific method but fleshes out the process a little. Although this handout takes each section in the order in which it should be presented in the final report, you may for practical reasons decide to compose sections in another order.

For example, many writers find that composing their Methods and Results before the other sections helps to clarify their idea of the experiment or study as a whole. You might consider using each assignment to practice different approaches to drafting the report, to find the order that works best for you.

The best way to prepare to write the lab report is to make sure that you fully understand everything you need to about the experiment. To make sure you know enough to write the report, complete the following steps:, write a lab report. Consult your lab supervisor as you perform the lab. Plan the steps of the experiment carefully with your lab partners. Also, take some time to think about the best way to organize the data before you have to start putting numbers down.

If you can design a table to account for the data, that will tend to work much better than jotting results down hurriedly on a scrap piece of paper.

Record the data carefully so you get them right. Lab groups often make one of two mistakes: two people do all the work while two have a nice chat, or everybody works together until the group finishes gathering the raw data, then scrams outta there. Was the hypothesis supported? Did you all get the same results? What kind of figure should you use to represent your findings? The whole group can work together to answer these questions.

Consider your audience. Well, yes—but again, think beyond the classroom. If you write with only your lab instructor in mind, you may omit material that is crucial to a complete understanding of your experiment, because you assume the instructor knows all that stuff already. Try to write towards a student in the same course but a different lab section. Alternatively, write a lab report, you could envision yourself five years from now, after the reading and lectures for this course have faded a bit.

What would you remember, and what would you need explained more clearly as a refresher? Then we can formulate a logical organizational strategy for the section. The inclusion of the purpose sometimes called the objective of the experiment often confuses writers. The biggest misconception is that the purpose is the same as the hypothesis, write a lab report. Not quite. The purpose is broader, and deals more with what you expect to gain through the experiment.

In a professional setting, the hypothesis might have something to do with how cells react to a certain kind of genetic manipulation, but the purpose of the experiment is to learn more about potential cancer treatments, write a lab report. In a solubility experiment, for example, your hypothesis might talk about the relationship between temperature and the rate of solubility, but the purpose is probably to learn more about some specific scientific principle underlying the process of solubility.

For starters, most people say that you should write out your working hypothesis before you perform the experiment or study. Many beginning science students neglect to do so and find themselves struggling to remember precisely which variables were involved in the process or in what way the researchers felt that they were related. In other words, explain that when term A changes, term B changes in this particular way.

Readers of scientific writing are rarely content with the idea that a relationship between two terms exists—they want to know what that relationship entails. Put more technically, most hypotheses contain both an independent and a dependent variable.

The independent variable is what you manipulate to test the reaction; the dependent variable is what changes as a result of your manipulation, write a lab report. In the example above, the independent variable is the temperature of the solvent, and the dependent variable is the rate of solubility.

Be sure that your hypothesis includes both variables. You need to do more than tell your readers what your hypothesis is; you also need to assure them that this hypothesis was reasonable, given the circumstances.

If you did pluck it out of thin air, your problems with your report will probably extend beyond using the appropriate format. But you can also motivate your hypothesis by relying on logic or on your own write a lab report. Even such basic, outside-the-lab observations can help you justify your hypothesis as reasonable. Generally speaking, authors writing journal articles use the background for slightly different purposes than do students completing assignments.

In any event, both professional researchers and undergraduates need to connect the background material overtly to their own work. Once you have expressed your purpose, you should then find it easier to move from the general purpose, to relevant material on the subject, to your hypothesis. In abbreviated form, an Introduction section might look like this:. Again—these are guidelines, not commandments. Some writers and readers prefer different structures for the Introduction.

The one above merely illustrates a common approach to organizing material. Ultimately, others must be able to verify your findings, so your experiment must be reproducible, to the extent that other researchers can follow the same procedure and obtain the same or similar results. To this day, the viability of cold fusion is debated within the scientific community, even though an increasing number of researchers believe it possible.

So when you write your Write a lab report section, keep in mind that you need to describe your experiment well enough to allow others to replicate it exactly. Writers often want to include the results of their experiment, because they measured and recorded the results during the course of the experiment. But such data should be reserved for the Results section. In the Methods section, you can write that you recorded the results, or how you recorded the results e.

As you draft your Methods section, ask yourself the following questions:. Describe the control in the Methods section. Here is an example:. Organization is especially important in the Methods section of a write a lab report report because write a lab report must understand your experimental procedure completely.

Increasingly, especially in the social sciences, using first person and active voice is acceptable in scientific reports. Most readers find that this style of writing conveys information more clearly and concisely.

This rhetorical choice thus brings two scientific values into conflict: objectivity versus clarity. The Results section is often both the shortest yay! Your Materials and Methods section shows how you obtained the results, and your Discussion section explores the significance of the results, so clearly the Results section forms the backbone of the lab report.

Before you write this section, look at all the data you collected to figure out what relates significantly to your hypothesis. Resist the urge to write a lab report every bit of data you collected, since perhaps not all are relevant. Nothing your readers can dispute should appear in the Results section. Most Results sections feature three distinct parts: text, tables, and figures. This should be a short paragraph, generally just a few lines, that describes the results you obtained write a lab report your experiment.

Feel free to describe trends that emerge as you examine the data. Although identifying trends requires some judgment on your part and so may not feel like factual reporting, no one can deny that these trends do exist, and so they properly belong in the Results section.

As in the Materials and Methods section, write a lab report, you want to refer to your data in the past tense, because the events you recorded have already occurred and have finished occurring. Tables are useful ways to show variation in data, but not to present a write a lab report deal of unchanging measurements.

How useful is this table? As a rule, write a lab report, try not to use a table to describe any experimental event you can cover in one sentence of text. When you do have reason to tabulate material, pay attention to the clarity and readability of the format you use. Here are a few tips:. Compare this table, in which the data appear vertically:. The second table shows how putting like elements in a vertical column makes for easier reading.

In this case, the like elements are the measurements of length and height, over five trials—not, write a lab report, as in the first table, write a lab report, the length and height measurements foreach trial. This convention exists because journals prefer not to have to reproduce these lines because the tables then become more expensive to print.

Figures How do I include figures in my report? Although tables can be useful ways of showing trends in the results you obtained, figures i, write a lab report. Lab report writers often use graphic representations of the data they collected to provide their readers with a literal picture of how the experiment went.

Under the same conditions, you would probably forgo the figure as well, since the figure would be unlikely to provide your readers with an additional perspective. The strength of a table lies in its ability to supply large amounts of exact data, whereas the strength of a figure is its dramatic illustration of important trends within the experiment.
