Included within discussions on each of the various components of a lab report, are discussions on a number of common shortcomings. Common problematic areas with grammar are also addressed in the scientific word usuage section. When writing your lab reports, the two most important pieces of advice are: • Prepare well. You should master the background material before ever setting pen to paper. Also, you should outline the main points that you will make in each section before you begin writing the report. • Edit, edit, edit. You need to edit and re-edit your report. First (or second or third) drafts are never-without exception-as clear as they should be. This step is where you "clean up" your writing. Professionals spend much of their time revising reports and papers to prepare the best possible product. The two fundamental concepts to keep in mind while writing are (i) yourmessage, and (ii) your audience. Your Message: What do you wish to communicate? Your message should basically answer the following three questions: • What did you do? You should provide enough detail about your experiment so that the reader can reproduce your results. • What were your results? This consists of your data and the analysis of that data. • What is the significance of your results? Explain why your results are important and provide a context for your experiment. In other words, describe how your work fits into the "big picture." Your must always keep in mind the main point(s) you mean to communicate. Keep your writing simple and to the point. In particular, extensive rambling is a sign that you either don't know the material, or that you have not organized your ideas well. Don't try to impress your audience with your extensive knowledge of peripheral topics. Your Audience: Who is reading your report? As you compose your report, you must always keep your audience in mind. And I don't mean your course instructor! Lab reports are meant to be read by your academic peers. Although you must assume that your readers have general training in science and engineering, don't assume a familiarity with details that are very specific to your experiment. For example, if you were to write a report on a Gravimetric Determination of Sulfate, you would assume that your average reader would only need to be reminded of the general principles of gravimetric analysis--so you need only provide a brief (1 paragraph) summary of those principles. However, details that pertain to your specific experiment--analysis of sulfate using a certain reagent--might need to be explained more fully. The following format is standard for 3rd and 4th year science/engineering labsin our department: 1. Title page 2. Abstract to summarize the experiment and important results. 3. An Introduction section to describe the purpose of the work and provide necessary background information. 4. A section to present the Results, often with tables and charts. 5. A Discussion of results is necessary to present conclusions and the significance of the work. 6. A list of Conclusions and Recommendations. 7. A separate appendix for Raw Data 8. A separate appendix for Sample Calculations 9. A separate appendix for Error Analysis. Note: Some lab courses may require a Materials/Metho

FAQs

What are the key advice points for writing a lab report?

Prepare well by mastering background material and outlining section points before writing. Edit repeatedly because first drafts are rarely clear enough without revision.

What should a lab report’s message address?

It should answer what was done, what the results were (data and analysis), and why the results matter by providing significance and context within the broader picture.

Why is audience awareness important in lab report writing?

Lab reports are meant for academic peers, so the writing should include sufficient general scientific/engineering background while explaining experiment-specific details more fully.
