In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

In this fun hands-on activity, learners create a safety device to protect an egg "passenger" in a toy car crash. Learners experiment with different solutions to this very problem.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

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

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?

In this activity, learners construct paper airplanes that twist and turn.

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 activity, learners explore density and buoyancy as they design and construct rafts.

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

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

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

This activity teaches combustion as the interaction of a fuel source and oxygen.
