In this activity, learners build a carousel toy that spins when pushed down.

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 collection of demonstrations, learners explore Newton's Laws of Motion.

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

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.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

Build your own version of the classic physics toy using simple materials.

Learners construct a rocket from a balloon propelled along a guide string.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners build an old-fashioned paddle boat out of 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.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.
