In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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 board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

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.
