More about Laws of Motion

Newton's 3rd Law of Motion describes an action and reaction. We saw this when the "paddle" on the carton boat was wound up on a rubber band and then allowed to rotate and make the carton boat travel the length of the bathtub.

The Ping Pong Popper was fun for each of my Gs because I let each one make the project and "shoot" each other with ping pong balls as well as heavier rubber balls. We compared the distance each could travel.  The re-use of toilet paper holders was wonderful ;-)
