In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

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

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

In this activity, learners explore rocketry and the principals of space flight.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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 activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners create painting machines that can paint moving forwards and backwards.

This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

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

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.
