Plan what you are going to say before you say it! You do not need to appear in the video throughout, but I should see you at least some and hear you for the entire post-interview section. Props, diagrams and photos can be used, if desired. Upload this video to this shared Google folder by the end of Sunday, 11/4.

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!
