Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

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 quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

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

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

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this physics activity (page 4 of the PDF), learners will--using nothing more than a coat hanger and some string--explore and understand sound energy and how it moves.

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

In this physics activity (page 4 of the PDF), learners will construct their own spiral "snake" and use it to explore the relationship between heat and kinetic energy.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

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

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.
