It's time to get moving! Explore Newton's laws of motion and get everyone involved with this classroom set of 30 air pucks. No need for an air table-the pucks float on a cushion of air above any smooth, flat surface as a result of air escaping from a balloon. Students do hands-on experiments to investigate the principles of inertia, collisions, velocity, and acceleration. The mass of the pucks can easily be changed by stacking washers or pennies on them. Kit includes reproducible student handouts, complete teacher notes with sample data and answers to all questions, 30 air pucks, and 50 balloons.
