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.

This activity guides the analysis of a published scientific figure from a study that investigated how salt affects the electron transport chain.

This short video explores how the symbiotic relationship between certain plants and fungi allows these organisms to survive in very hot temperatures.

In this hands-on activity, students simulate the effects of decreasing pH caused by rising levels of atmospheric carbon dioxide.

This activity analyzes a figure showing the atmospheric carbon dioxide concentration from 1958 to 2016.

This activity analyzes a published scientific figure from a study that tested whether corals can become more resistant to bleaching.

This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

This video describes the work of biologists Steve Palumbi and Megan Morikawa, who use field and controlled experiments to understand the mechanisms that allow some corals to tolerate a greater amount of heat stress than other corals.

In this talk, marine biologist Stephen Palumbi discusses how coral reefs are threatened by climate change and how to protect them.

In this talk, biologist Anthony Barnosky discusses what steps can be taken to avoid a sixth mass extinction.

This interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.

This video follows biologist Liz Hadly in Yellowstone National Park as she discusses how ecosystems are threatened by warming temperatures.
