In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

The demonstration/experiment provides quick proof that air has mass.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

In this physics activity (page 6 of the PDF), learners will try to keep a marble in a bottomless cup without touching the marble inside.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon
