Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.
