Remember that lab reports are individual assignments. You may have a lab partner, but the work that you do and report on should be your own. Since you may see this material again on an exam, it is best that you know it for yourself. Always give credit where credit is due on your report. You don't want to plagiarize the work of others. The Report condenses and explains all the steps of the investigation, the results achieved, the analysis of those results, and the conclusions deduced from them. The report is the permanent record.


How to Write a Lab Report - Steps and Template


This handout offers general guidelines for writing reports on the scientific research you have undertaken. We will describe the conventional rules regarding format and content of a lab report as well as try to explain why these rules exist so that you will have a better understanding of how to undertake this type of writing. In your science class you participated in an experiment, and now you must write it up to submit to your teacher.

You think that you had sufficient understanding of the background, designed and finished the study well, were able to gain useful data, and could to apply the data to draw conclusions about a particular scientific process or principle. However, how do you go about writing all that? What expectations does your teacher have? To avoid guesswork in trying to ascertain this, try to think beyond the context of a classroom. Indeed, you and your teacher are both members of a scientific community, and participants in this community often share the same values.

As long as you appreciate and understand these values, it is likely that your writing will satisfy the expectations of your audience, which includes your teacher. What is your motivation for writing this research report? Broadly speaking, steps of a lab report, individuals perusing a scientific hypothesis have an obligation to the rest of the scientific community to report the findings of their research, especially if these make a contribution to or contradict previous ideas.

Great question. Here is the essential format that scientists adhere to for research reports:, steps of a lab report. Ultimately, however, the IMRAD format was created to be a textual reflection of the scientific method. As you will likely recall, the scientific method requires developing a hypothesis, putting it to the test, and then determining if your results support the hypothesis. Essentially, the format for a research report in the sciences reflects the scientific method but adds to the process a little.

Below you can see a table that demonstrates how steps of a lab report written section corresponds to the scientific method and what information it offers to the reader. Conceptualizing your research report as derived from the scientific method albeit fleshed out in the ways noted above. Our advice enables you to meet the expectations of your audience, steps of a lab report.

We will continue by explicitly drawing connections between each component of a lab report to the scientific method, and then provide the rationale regarding how and why you must elaborate the respective section. Although this handout addresses each component steps of a lab report the order, it should be presented in the final report, for practical reasons you may decide to write your sections in a different order.

For instance, steps of a lab report, often writers find that writing the Methods and Results section before the others helps them to clarify their steps of a lab report of the experiment or study as a whole. You might think about utilizing each assignment to try out different methods for drafting the report in order to determine which works best for you. The optimal way to prepare to compose the lab report is to ensure that you have full comprehension of everything you need to know about the experiment.

Clearly, if you do not really understand what happened in the lab, you will find it hard to explain it to another person. To ensure that you have sufficient knowledge to compose the report, complete the following steps:. Read your lab manual extensively, steps of a lab report, and far ahead of when you begin the experiment.

Consider the following questions:. Providing answers to these questions will promote a more complete understanding of the experiment, and this knowledge of the larger picture will enable you to write a successful lab report.

Consult with your lab supervisor as you undertake the experiment. If you don't know how to respond to one of the above questions, your lab supervisor will probably provide you with an explanation or guide you towards the proper response. In collaboration with your lab partners, plan the steps of the experiment carefully. The less you are hurried, the more likely you are to do the experiment correctly and accurately document your findings. Also, invest some time to consider the best way to organize the data before you have to start recording it.

If you can, create a table to account for the data; this will often work better than merely jotting down the results in a rushed fashion on a scrap of paper, steps of a lab report.

Record the data carefully to ensure that it is correct, steps of a lab report. You will be unable to trust your conclusions if you have erroneous data, and your readers will see you made an error if the other people in your group have "97 degrees, " and you have " Do everything in consultation with your steps of a lab report partners.

Frequently lab groups make one of two mistakes: two people undertake all the work while two spend the time socializing, or everybody works together until the group finishes gathering the raw data, then makes a hasty exit.

Steps of a lab report with your group members, even when the experiment is finished. What trends did you observe? Was there evidence to support the hypothesis? Did all of you arrive at the same results? What kind of figure or image should you employ to represent your findings? The whole group can work collaboratively to provide answers to these questions. Take your audience into consideration. You may think that audience is not important: it is just your lab TA.

True, but again think beyond the classroom context. If you write only with the instructor in mind, material that is crucial to a full understanding of your experiment may be omitted as you assume the instructor was already familiar with it. Consequently, you might receive a lower grade as your TA will not be sure that you have adequately grasped all of steps of a lab report principles at work. Or, write towards yourself five years later after the reading and lectures from this course are not so fresh steps of a lab report your mind.

What aspects would you retain, and what would you require to be more fully explained as a refresher? After you have finished these steps as you go through the experiment, steps of a lab report, you will be in a good position to draft a strong lab report.

For present purposes, we will consider the Introduction to comprise four basic elements: the intent, the relevant scientific literature, the hypothesis, and the reasons why you held that your hypothesis was viable, steps of a lab report. We will begin by addressing each element of the Introduction to explain what it covers and why it is significant. Then we will be able to develop a logical organization method for the section.

Including the purpose otherwise known as the objective of the experiment frequently confuses the writers. The largest misunderstanding is that the purpose is identical to the hypothesis. This is not completely accurate. We will address hypotheses shortly, but essentially, they contain some indication of what you expect your experiment to demonstrate.

The purpose goes beyond that and engages more with what you expect to achieve through the experiment. In a professional context, the hypothesis may pertain to how cells react to certain types of genetic manipulation, yet the purpose of the experiment is to gain knowledge about potential cancer treatments, steps of a lab report.

Reports at the undergraduate level rarely have such a wide-ranging goal, yet you should still attempt to maintain a distinction between your hypothesis and your purpose. For example, in a solubility experiment, your hypothesis might address the relationship between temperature and the rate of solubility, yet the purpose is likely to gain knowledge regarding some specific scientific principle underlying the process of solubility.

To begin with, many individuals maintain that you should write down your working hypothesis before you begin the experiment or study.

Steps of a lab report, beginning science students fail to do so and thus struggle to recall exactly which variables were involved or how the researches deemed them to be related. You will thank yourself later if you write down your hypothesis as you develop it. Regarding the form a hypothesis should have, it is a good idea to try to avoid being fancy or overly complicated — here the clarity is what is important, not an inventive style.

That is, explain that when term A alters, term B alters in this particular way. Audiences of scientific writing are seldom content with steps of a lab report notion that a relationship between two terms exists — rather, they wish to know what is entailed by that relationship.

Not a hypothesis: "It was hypothesized that there is a significant relationship between the temperature of a solvent and its solubility rate. Hypothesis: "It was hypothesized that when the temperature steps of a lab report a solvent increases, its solubility rate will likewise increase.

A suitable hypotheses should have both an independent as well as a dependent variable. The independent variable is what you alter to test the reaction; the dependent variable is what changes as a result of your alterations. In the example above, the independent variable is the temperature; the dependent variable is the solubility rate.

Both should be used in your hypothesis. You are required to contribute more than simply relating to your readers what your hypothesis is; you are also required to persuade them that this was a reasonable hypothesis, given the circumstances, steps of a lab report. That is, utilize the Introduction to make clear that you didn't just randomly select a hypothesis and if you did, problems with your report likely go far beyond using the appropriate format!

If you suggest that steps of a lab report particular relationship exists between the independent and the dependent variable, what made you believe your estimation might be supported by evidence?

However, you can also motivate your hypothesis by steps of a lab report logic or your own observations. If you are attempting to discern which solutes will dissolve more quickly, you might recall that some solids are meant to dissolve in hot water e. Alternatively, you can consider if you have noticed sugar dissolving more quickly in a glass of iced tea or a cup of coffee. Even such common, outside of the lab observations can help you establish your hypothesis as a reasonable one.

This component of the Introduction makes clear to your reader how you are building on the work of other scientists. If you imagine the scientific community are participating in a series of conversations addressing various topics, you will see that the relevant background information will indicate to your reader which conversation you want to engage with.

Broadly speaking, the reasons students employ the background differs to some degree from authors writing journal articles. Given that the audiences of academic journals are often professionals in the field, authors articulate the background so as to allow readers to determine the study's relevance to their own work.

Students, on the other hand, are writing with a much more narrow audience of peers in the course or their lab instructors. Consequently, it is necessary for students to make clear their understanding steps of a lab report the context for the experiment or study they have completed. For instance, if your instructor has been discussing polarity during class, and you are undertaking a solubility experiment, you might attempt to connect the polarity of a solid to its relative solubility in certain solvents.

In any case, both undergraduates as well as professional researchers must make a clear connection between the background material and their own work. After you have articulated your purpose, it should be easier to move from the general purpose to relevant material pertaining to the subject to your hypothesis.

According to Whitecoat and Labratthe molecules increase speed when subjected to higher temperatures Note, these are guidelines rather than firm exhortations.

The example above simply provides an sample of a common way to organize the material. Your Methods section should fulfill the readers' expectations; thus you must understand its purpose. We will review the purpose as we articulated it above: in this component, you will wish to describe in detail how you tested your hypothesis as well as make clear the rationale for your procedure. In the sciences, it is not enough to simply design and undertake an experiment.

Others must be able to verify your findings, so the experiment must be reproducible so far as other researchers could follow the same methodology and arrive at the same or similar results.
