In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners make a Benham Top to explore visual illusions and optics.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

In this engineering activity, learners design their own board games.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across
