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.

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.
