In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

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

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 moving air and the physics of lift and drag by constructing homemade wind tunnels.

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

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.

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 online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

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