Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?

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

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this physics activity, learners will explore buoyancy.
