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

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.
