Writing academic papers is part of learning. However, writing tends to scare most individuals, be they students or not. But you cannot survive school life without writing skills. This blog post will detail how to write an abstract for a lab report.

The first step in acquiring writing skills is learning the basics. After that, you need to practice to perfect the skill.

Writing begins as early as kindergarten when we learn the basics of reading and writing. In elementary school, we learn the different kinds of writing, which include a lab report.

A lab report, like any other academic paper, requires an abstract. However, due to its complexity, an abstract section is not required for lab reports in lower levels of learning, such as elementary school.

An abstract to an academic paper, not just a lab report, is important as it is usually the first thing teachers and instructors read. So, you have to learn how to write a good abstract.

This guide provides a quick overview of how to write an abstract for a lab report. By following these simple tips, you can improve your abstract and make it more likely to be accepted by your professor.

What is an abstract?

As mentioned earlier, academic papers require an abstract. The focus of this article is a lab report abstract. Therefore, let us first look at the outline of a lab report.

  1. The title of the abstract
  2. Abstract
  3. Materials and Methods
  4. Procedure
  5. Outcome
  6. Discussion
  7. Inference or conclusion
  8. References
  9. Appendices

Simply put, an abstract is a summary of your paper. A lab report abstract should mention the following:

  • The aim of the experiment and the research questions
  • The procedure used to experiment, in the methods section
  • The key findings in the results section
  • The major conclusions

The Abstract is the first section of your lab report. However, it is advisable to write it last. The idea is to write it after completely understanding the lab report. Remember, since the abstract is the introduction to your report, it will influence someone’s interest in reading your paper.

Types of abstracts

There are two types of lab reports:

  • Informational abstracts
  • Descriptive abstracts

The kind of paper you are writing dictates the type of abstract you write. Sometimes, the lecturer specifies the abstract format he wants. If the lecturer does not specify the format, you can choose between the two types of abstracts.

Informational abstracts

An informational abstract:

  • Provides a summary of all the sections in the lab report. Generally, an informational abstract will have a two-sentence summary of all the lab report sections except the appendices, references, and bibliography. Also, the abstract does not include illustrations, images, or graphs.
  • It has a length of approximately 10% of the whole report.

In essence, an informational abstract outlines the details of the lab report. Sometimes, the experiment does not go as planned, or you will make a discovery in the process. Such information has to be highlighted in the abstract.

You can use the format below to write an accurate informational abstract.

Purpose: Explain why the experiment is important. Also, state the reasons why anyone should be interested in the experiment.

  • Hypothesis: State your hypothesis of the experiment. Explain the problem the experiment solves or is intended to solve.
  • Materials and Methods: explain the steps or procedures used to experiment.
  • Outcome: Briefly state the significant results of the test or experiment. Indicate whether the findings support the hypothesis. Also, highlight whether or not the findings were as expected.
  • Conclusion: Summarize your findings and explain their significance. Explain your findings’ contribution to the advancement of knowledge or their contribution to society.

Descriptive abstract

A descriptive abstract is brief compared to an informational abstract. It is a very brief summary of the lab report. Still, those few words should give the reader an idea of what the lab report entails.

A descriptive abstract:

  • Has a maximum of 100 words (one paragraph)
  • States the aim of the experiment and the procedure used to experiment.

Because it is brief, a descriptive abstract does not discuss the experiment’s outcome, findings, and conclusion.

Tips for writing a good lab report abstract

The following are some useful tips when writing a lab report abstract.

Consider the length

If the instructor or lecturer does not specify the word count, length, or format, it is advisable to write a short abstract. Write an abstract of about 200 words or a maximum of two paragraphs.

However, when writing an informational abstract, the lab report’s length dictates the abstract’s length. Sometimes, it can go up to two pages depending n the scientific methods that need to be written.

2. Write the abstract last

The abstract comes just after the title page. However, it should be written last.

Remember, the abstract is a summary of the lab report. By the time you finish writing the rest of the report, you have a clear idea of what it is all about.

3. Third-person point of view

A lab report abstract should be written in the third person point of view. Do not use words such as ‘I,’ ‘We,’ or ‘Us.’ Instead, use ‘it,’ ‘this,’ and ‘that.’

4. Do not include information not in the lab report

As mentioned earlier, the abstract is the last section of the lab report to write. It is possible to remember a new piece of information when writing it. However, remember that an abstract is a summary of the report. Therefore, please do not include any information not in the lab report, no matter how essential.

5. Proof your abstract

The abstract is a brief section of the lab report. And it comes last. Students tend to rush over it for these two reasons, which is wrong.

Again, remember the abstract is the first section of the report. Therefore it needs to interest a reader. So, before submitting the report, ensure that the abstract does not have grammatical errors, has flow, and makes sense.

6. Consider keywords

In today’s online world, it is important to consider keywords when writing. In your abstract, consider the search phrase one would use to find your work.

Add these phrases where you deem them relevant, not only in your abstract but also in other sections of the lab report. These phrases allow people to find your work online easily. You never know if your work will get published online.
