The length and structure of lab reports may vary. Always consult your professor before doing the work. Lab reports comprise about 25% of your grade at the end of your course. Therefore, it is vital for students to acquire skills needed to write this type of assignment. The instructor always expect the learners to submit unique work.

Explain how the variations in your experiment influenced the final results. Even if you have an excellent format of the content, you must have a proper organization of your points.

Insights of Writing a Perfect Lab Report

•   Avoid the use of first-person pronouns.

•   Give a full background of the topic to enable all readers to understand its concepts.

•   The results and discussion section should constitute the highest percentage of your lab report.

•   Avoid repetition of information in your results.

•   Planning. Take adequate time to make plans for the report as this will help you to get desired results at the end of your experiment. Failure to plan for the work will lead to poor grades. Ensure that you have vast knowledge about the subject area. If you have some ideas about an experiment, find out whether someone else had done the work before. There is no need for you to carry out a study that has already been documented.

As you read the existing literature, find out whether there are any gaps in knowledge and purpose to provide new ideas. Take time to set the experiments as failure to do this will lead to inaccurate findings.                                                                                                                        

•   Take detailed notes. It will help you to write your lab report logically and with ease. Carry a notebook to the lab to ensure that you note down all details of the experiment. It is advisable to make notes as you do the experiment as you will remember everything that transpired. Write down important points using an ink pen instead of a pencil as you may erase your observations by mistake if you use the latter. Ensure that your notes are legible as you will need them to write the lab report. A friend may also borrow your book.

•   Make good use of tables and graphs in your work. Avoid them unless you find them necessary to support your findings. If you choose to include tables and graphs, number and give a title for each of the diagrams. The diagrams must also display the appropriate units of measurements and in the correct order.

•   Be concise in your report. Avoid writing too many words to fill your working space. The assignment should not be written like a descriptive narrative. However, ensure that all your information is accurate. Use simple language as much as you can as some of the readers are not conversant with complex scientific terms. Only details that are relevant to the lab report should be included in your assignment.

•   Learn from others. Lots of people have written lab reports in the past. Before writing your work, make sure you review some of the existing work as you may get some insights.
