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

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this activity, learners model erosion using a clear shoebox and sand or soil.

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

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

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

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

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

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

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

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 model how the Moon's volcanic period reshaped its earlier features.

This multi-part activity from the National Parks Service blends the science of plate tectonics with the culture and history of places with dramatic geologic landscapes.

In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

In this activity, learners will learn how igneous rock, metamorphic rock, and sedimentary rock are formed as part of the rock cycle and that the same forces that produce/change rocks also produce/chan
