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.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

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

In this activity, learners make different shapes that hold exactly one mole of gas (air).

Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

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 explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this chemistry demonstration, acid rain is simulated in a petri dish.
