Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

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 construct a simple game to test their hand-eye coordination and steadiness of hand.

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

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

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

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

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners examine what happens when a tube spins in two directions at once. They push on a cardboard tube causing it to spin along its length while at the same time turning from end-to-end.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

In this physics activity, learners will investigate the strength of egg shells.

Learners construct and launch paper helicopters.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.
