In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

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

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

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

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

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 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.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.

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 activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.
