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.

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

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

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

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

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
