The large gear mechanisms in this compound machine enable students to feel the mechanical advantage gained by using gears and pulleys. Let students first experience how much force is required to pull a classmate on a scooter across the floor. Then, weave the rope through the large gear train and have the student use the handle to pull in the classmate. Two separate devices provide gearing up and gearing down opportunities. Requires scooter and cones, not included.
