In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

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 use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

In this physics activity, learners will explore buoyancy.

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

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

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

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.
