How to Write a Good Lab Report

As a STEM student, you will likely write tons of lab reports during the education process. This academic paper is essential for studying science, mathematics, technology, or engineering. And if you want to create a good lab report, it is necessary to know the basic writing guidelines and rules.

Usually, instructors provide specific guidelines to students, but they need more to understand how to structure and write a lab report. That’s why our guide will be helpful for you! These diversity essay guidelines will teach you everything needed to create a good lab report.

What Is a Lab Report?

The easiest way to define a lab report is by explaining the purpose of writing it. A lab report is used to communicate the methods and findings of a particular laboratory experiment, evaluate these results, and interpret them in the context of a specific scientific concept.

It is typically a 5-10 page document that is supposed to be read by people who have basic knowledge in a particular scientific field but are unfamiliar with the experiment described in the report. Thus, in writing this assignment, students should use formal, straightforward language and communicate information precisely, without digression from the main subject.

Also, writing in the third person is required, so don’t use the pronouns “I / We” in your lab report. And all the processes should be described in the past tense. That’s the main requirement for the lab report writing style.

Now, let’s dive deeper and talk about the correct structure of a lab report and how to write a diversity essay fast. Keep reading to find out more details.

How to Structure a Lab Report

The structure of a lab report differs from many academic assignments, but is similar to a research paper’s structure. Usually, a lab report consists of 5 main sections:

  • Introduction
  • Methods
  • Results
  • Discussion
  • Conclusion

Also, you can be required to write an abstract for your report and add a reference section and a Figures & Tables section at the end.

The structure may be different, depending on the scientific field you study. Also, professors frequently provide some specific requirements for writing lab reports, and you should follow them in this case. Finally, it will guarantee a good grade for your paper.

How to Write an Abstract for a Lab Report

An abstract is an overview of your lab report that provides the readers with the primary information of your experiment and critical findings. The abstract should be 200-300 words or less. Here is what information you need to provide in this section:

  • The context of your research
  • The purpose of your research
  • Utilized methods
  • Key findings
  • Final results.

After writing all other chapters of your lab report, it is recommended to write an abstract. This way, you can summarize all the sections and create a precise abstract.

Lab Report Introduction

The introduction to a lab report is the section that provides preliminary information about the scientific question you researched and your experiment. Introduction paragraphs should give your audience a clear idea of the context of your investigation.

To write a good introduction, include the following information in the section:

  • Background information of your research
  • The purpose of conducting research/experiment on a chosen topic
  • The hypothesis/theory that will be the main focus of your experiment.

The introduction should be brief but provide detailed information, so your audience will understand the background and importance of your experiment. Usually, 2–3 paragraphs are enough for a comprehensive yet precise introduction.

Lab Report Main Body

As we told earlier, the following sections after the introduction are Methods, Results, and Discussion. These sections are the main body of a lab report, as they convey research methods, key findings, and analyze results. Let’s look at some rules on how to write these sections correctly.


Before discussing the findings of your experiment, it is necessary to describe how you conducted your research and what equipment, materials, and methods you utilized for the experiment. This section can take 2–3 pages, as it is critical to explain precisely your investigation procedure in a lab report.

When writing the paragraphs, follow the logical sequence by presenting information in the following order:

  • Overview — Write a few sentences that briefly describe the process of your experiment. Don’t mention any specific procedures or other details.
  • Materials — Provide a list of materials and equipment used for experimenting.
  • Procedures — Describe utilized data collection methods, essential equations, analysis procedures, etc.

It is critical to describe the procedure step-by-step as if your readers will repeat the experiment after you and need to know all the stages. Thus, provide information precisely and include all necessary details. If you need to display some data in diagrams and tables, it is better to add them in the appendix to your lab report.


In this section, you need to perform all calculations and report the results of your experiment. To make your calculations clear for the audience, mention utilized equations and add descriptions in words to explain your choice and the calculations procedures.

The results can be presented in words, diagrams, and tables. Depending on your research topic or specific guidelines from your professor, you will choose different forms for delivering the key findings of your experiment.

Also, you can include the estimation of experimental uncertainties in the result section. Finally, write a paragraph regarding a standard error and variations of the critical estimates.


The last section of the main body interprets all findings you describe in the previous quarter. Here, you should:

  • Identify the main results
  • Compare results with your expectations
  • Explain how the findings help to answer your research question
  • Determine whether the hypothesis stated at the beginning is accepted.

When you discuss your findings, it is essential to write clear sentences. Use concise language and add details that make your statements unambiguous for your readers.

How to End a Lab Report

The concluding paragraph of a lab report should be a maximum of a few paragraphs. In this section, you need to briefly summarize what experiment was conducted, what were the key findings, and how you interpreted them. But, again, make it short and precise without repeating all the details.

After the conclusion, add the appendix with the tables and diagrams used for visualizing your statistical data and the results of your experiment. Also, you can add the reference section if you cited other research papers and articles in your work.
