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 use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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

In this physics activity, learners will explore buoyancy.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

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 build water-propelled engines from soft drink cans.
