Lab Reports

Laboratory conduct

  • Observe safety precautions at all times.

  • During the lab sessions, your first objective is to learn about the system, component, or controller that you are working on. Data taking is for reporting purposes, so plan your experiments accordingly.

  • Lab reports should be type written, succinct, but self-contained. Page limits are sometimes imposed. They should contain your observations (use well labeled graphs!) as well as explanations, and if appropriate, mathematical analysis.

  • The exercises on the lab sheets are base line exercises. You are encouraged to formulate additional questions and to test them using the lab setup. How much you learn depends on how willing you are to ask and answer additional questions.

  • Expect to do most of your learning in the lab or in front of your computer, rather than from lectures.

  • Cheating will be dealt with severly. Your lab reports and your modeling exercises should be your own work, and reflect your understanding of the problem. You are encouraged to work with others to understand the material, but the lab reports must be your own work.
