What Is the Structure of Lab Report

At the beginning of the lab report, the student describes the purpose of the work and the tasks to be solved, as well as objectives are methods for achieving a set goal.

The educational goal of the laboratory work is the result that the student plans to achieve. When formulating a goal, action verbs should be used: explore, study, check, determine, and so on. After that, the object of research and the tasks that will be solved on the way to the goal are indicated: measure, consider, conduct, develop, and the like.

The volume of the introductory section depends on the depth of the research and the complexity of the work and can range from one paragraph to half a page.

Theoretical part

The content of the theoretical part of the lab report depends on the discipline in which the laboratory work is done. This may be a description of formulas, theorems, measuring instruments and methods, or the history of the study of the problem. All of this is summarized and as concise as possible.

Practical part

The practical part describes the technical equipment during the experiment, methods, and work progress.

Particular attention should be paid to the description of the results obtained during the experiment and their analysis. Intermediate results are recorded in tables that complement the description of the progress of work.

The practical part of the lab report is compiled so that the reader can understand from it that the author independently performed all the actions and reproduce his actions.

At the end of the practical part, a table is usually drawn up, which clearly displays all the results obtained (and sometimes the initial conditions). If intermediate results were required in the laboratory work, then they are also recorded in the tables.

Use the same design of graphic objects. For example, the lines in the table should have the same thickness and the same font, the size of the pictures should also not differ. 

Do not overdo the lab report with graphic elements, they can complicate the perception of information.

Images and tables should follow the text that refers to them. Graphic elements should be aligned to the center of the page.


The lab report ends with a conclusion and results. In them, the student fixes the final results of the experiment, lists the solved problems, and draws a conclusion.

The meaning of the conclusion of the lab report corresponds to a given goal (achieved or not achieved). In the final part, which is presented in the form of a conclusion in the lab report, it is necessary to highlight what the actions led to and what is the result.

Useful tips on Writing a Lab Report

  1. Before starting writing the lab report, familiarize yourself with the report format for your department and write a short plan for the future report. This way you don’t miss important intermediate data or information about the progress of the experiment that you may need.
  2. If during the experiment you need to record a lot of data, enter them immediately into a table of the format that will be needed in the report. As a result, you will already have some of the data entered. This is more convenient than typing this information from a draft later.
  3. Ask undergraduates about which applications are convenient for calculations for this laboratory work. Sometimes outdated software is recommended in the manual or there are no tips on this topic at all.
