In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

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.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners watch a figure "magically" float up through the air.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.
