Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.

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.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

In this activity, learners explore the real science behind an egg drop "magic trick." Learners will wow their families by harnessing gravity, friction and motion to make 3 eggs fall off of their pedes

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

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

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