Understanding Global Change

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

Written in Chalk

This activity explores images of chalk formations and coccolithophores, which serve as phenomena for learning about the interactions between biological and geological processes.

Animated Life: Pangea

This animated short video celebrates the early 20th-century German astronomer and atmospheric scientist Alfred Wegener, who first proposed that continents once formed a single landmass and had drifted apart.

Earth Systems Activity

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

Plate Tectonics

This animation provides an overview of some basic concepts from plate tectonics, a fundamental theory in earth science.

Finding the Crater

This activity supports concepts covered in the film The Day the Mesozoic Died. Students will analyze geological evidence from ten different sites around the world to predict the location of the asteroid impact that caused the mass extinction at the end of the Cretaceous Period.

The Principle of Isostasy

This video provides a demonstration of the principle of isostasy, the idea that the continental crust “floats” on the underlying mantle.

The Geologic Carbon Cycle

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

EarthViewer

This interactive module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.

Determining the Size and Energy of the K-T Asteroid

This activity allows students to calculate the mass, size, and kinetic energy of an asteroid that struck Earth 66 million years ago, based on the total abundance of iridium in a sediment layer. It supports concepts presented in the short film The Day the Mesozoic Died.
