In this activity, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.

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

Learners model the processes that formed some of Earth's largest mountain ranges: the Himalayas, the Andes, and the Alps.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

In this activity, learners drop impactors onto layers of graham crackers!

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

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.
