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 model hot spot island formation, orientation and progression with condiments.

Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.
