Contents of the Prelab Report

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.
