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

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

Historically, sea floor mapping (bathymetry) was done by soundings.

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.
