In this activity students will investigate the forces and motion related to a small, easy to build balloon-powered car. Students will design and build a balloon-powered car to specifications based upon a desired goal: 1) speed and/or 2) distance. Students will use a motion detector to measure the speed and acceleration of the balloon-powered car. They will also investigate the effects of the size of the propulsion tube on the speed and distance of the car.
