Millions of organisms can live in and around a body of water.

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.
