"When Rubber Meets The Road"
A rubber band twisted around the axle of a plastic car provides the force that moves the car forward. In this workshop, fifth-grade students continue their exploration of force and motion by recording and comparing the distance a vehicle travels under various conditions. Students predict the distance the car will travel by counting the number of twists in the rubber band, and observe the car's speed as it rolls across the floor. When the force of the rubber band stops acting, the force of friction slows the car to a stop. G
