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.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

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 use tinfoil to build and test their own boats - which designs will float, and which will sink?

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.
