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.

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

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

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

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners will make a model rocket to test the phrase "what goes up must come down." Learners will power their rockets with air pressure, and soon discover the effects of air resistan

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 engineer a paper helicopter that spins to the ground when dropped.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

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 work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

Students design and build their own parachutes in this hands-on engineering project.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners construct a simple air pressure launcher for paper rockets.

Students design and create their own air-powered rockets, in this hands-on activity.
