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 design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

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

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

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 design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

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 activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.
