In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

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 create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

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

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 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.

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

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

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.
