The lab report includes three parts:
1. Prelab report
Put prelab report on the bench before the class. The
associate TA will sign up on your report. You should hand in
it with your final report in the end. If there is no signature, your
prelab report will be viewed as late submission.
2. Lab records
Write down the observation and the experiment data. After
finishing the experiment, ask the TA to check and sign up for
your final report.
3. Final report
Short version: Hand in the report at the ending of the class.
Full version: Hand in the report in the next week of the class.
