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.

In this engineering design challenge, learners build an air-powered spinning machine.

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

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
