Guidance

Organize your experiments, keep detailed records of each construction, create tables based on your observations. Basically record everything you do. (Drawing diagrams or take screen shots is a great idea)

This is a student-generated lab, which means you are creating unique experiments. I will not provide you with prescribed circuits.

Your data must prove evidence of your generalizations. The final product should be reproducible through an equation.

This is a formal lab write-up.
