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 quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
