2. Identify the Audience

For every writing type, it is essential to identify who you are writing it for. Similarly, when writing a lab report, determine the targeted audience first. For example, if you are writing a report for academics, your audience will be your instructor.

If the audience is of another discipline, make sure to explain the jargon and technical terms used. It is to make your report understandable for everyone.

The title and the abstract are the two most visible and striking parts of a lab report. These two elements will help the writer get more attention from the readers, so they should be written perfectly.

To make your title interesting, make sure that it reflects what you have done in the experiment and some interesting findings. For your abstract, keep it concise. It should be based on just one paragraph of 200 words.

      • What is the setting of the issue or problem?
      • What is the issue you are trying to solve?
      • Why is the problem important to discuss?
      • Is the problem solved, or is it still unsolved?

Along with the background, the introduction contains crucial information about the experiment or the report. This includes:

      • Why was the problem so difficult to solve?
      • How did the writer solve the problem?
      • The circumstances in which the findings and results are applicable
      • Major results

This information can be presented right after the introduction and at the end of the body section, depending on the writer’s preference.

The differences can be presented in the form of charts or graphs to make them understandable. While giving a reference to the other’s work, make sure to cite it properly. It is to avoid plagiarism and ensure the authenticity of your work.

After providing the information in context to the previous work, state your results clearly. Your experiment results will be based on the lab you have worked in, how it performed, its implementations, and the objective of the experiment. Present all the data from your experiment in this data without providing personal opinions and subjective comments.

The result section always remains objective, even if your data confirms the hypothesis.

It is believed that readers tend to pay more attention to the title, abstract, introduction, and conclusion of the report. For this purpose, make sure that they are interesting and informative.

If the prompt requires, create a separate section for discussion and a whole new section for your conclusion.
