Lab Reports

Five of the laboratories will require a complete written report. The reports are to be turned in by e-mail to scott.yost@citadel.edu in MS Word format. Each report is due at the beginning of the following laboratory.

While you will work together in the laboratory, at its end, each student will have an individual record of the experiment, and will use this record to write a personal laboratory report. The lab report is absolutely not a team or joint project. You should have the same data as your partner, but its interpretation should be your own, and anything written about it must express your own ideas and be in your own words. If you include graphs or charts that only one team member prepared, the report must show who is responsible. You should take turns producing graphs and tables.

The manual gives good advice on what to do and to avoid when writing a report. A report should be complete, but not excessively wordy, and should avoid repetition and overgeneralization. When writing the discussion, be aware that it is impossible to prove anything using an experiment. You can only confirm agreement with a theory within the precision of your experiment. The discussion should show whether the agreement was within reason for your procedures, based on an estimate of the errors in the data you acquired. The sources of the errors should be discussed. If you do not agree with the theory, you should discuss possible reasons, and make suggestions for improving the measurements. If your grades on laboratory reports are unsatisfactory and you do not understand why, be sure to schedule an appointment to discuss this in detail, and bring your reports to the meeting. If English skills are a problem, you may also wish to contact the Citadel Writing and Learning Center. See www.citadelwritingandlearning.com.

Laboratories that do not require a complete report will require a data analysis sheet. This normally consists of the Excel worksheet produced during the laboratory session, including any graphs made, and with the addition of a brief statement addressing the following points:

• Did your results agree with the expected results within the bounds of experimental error? Justify your conclusion.
• What main sources of error influenced your result, and can you estimate the size of these errors? Could you have done anything better to reduce the errors?

As noted above, the data analysis sheets must clearly show who is responsible for any graphs and tables included, and you should take turns producing these items. The answers to the above questions must be your own, and not shared.

If in doubt, ask before submitting your work, but it is always safest to clearly show who made each contribution.
