**Coming Up:** A few days after returning from Thanksgiving break, I will assign "the mousetrap car project", in which you will need to design and build a small car powered by a single mousetrap. The project also includes a video recording of you explaining the physics behind the car's operation. Stay tuned! They're pretty fun to build and race!
