+ | ==== Project 15B: Design your own review ==== | ||
+ | Your group is to design two exam problems that can be used as practice problems by the class. As a reminder the topics for the final exam include: | ||
+ | |||
+ | | ||
+ | - Circuits | ||
+ | - Magnetic fields/ | ||
+ | - Induction | ||
+ | |||
+ | Your design should include both the **problem statement** and the **solution** to the problem. Imagination is a plus. Try to come up with a context for your problem (not just "There' | ||
+ | |||
+ | A good solution will not just be equations but will include some commentary, so everyone can follow your work. | ||

- | Good Luck! | + | At the end of the project, please email your problems & solutions to: mcpadden@msu.edu. We will post all of the class' |
