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?

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this physics activity, learners will explore buoyancy.

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

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