Lab Quiz and Lab Report:
No pre-lab, but we will have weekly lab quiz. The Lab Report is a collaborative effort between you and your lab
partner. Reports are due by midnight on Friday of lab check-off.
Final Project:
See the course/laboratory website for project description. This project will not be completely defined. We will
go through a few negotiation sessions. You get to ask all the questions you want.
