Students model different densities of Jupiter’s moon Europa to investigate what might lie beneath the icy surface.

Students explore the relationship between magnetism and electricity to model how scientists determined that Jupiter's moon Europa has a subsurface ocean.

In this illustrated math problem, students use pi to measure the water depth of an area mapped by the CORAL mission.

In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

Students draw and interpret topographic maps while learning about technology used to map Earth's surface, the seafloor, and other worlds.

This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat being trapped on our warming world.

Students make predictions and observations about how ice will melt in different conditions then compare their predictions to results as they make connections to melting glaciers.

Students learn the difference between land ice and sea ice and make a model to see how the melting of each impacts global sea level.
