This video examines the thawing of permafrost due to changes in climate and shows examples of the impacts that warming temperatures have on permafrost in the Arctic, including the release of the greenhouse gas methane. Dramatic results are shown, including sink holes forming on the landscape and beneath buildings, roads, and other infrastructure, causing some communities to relocate.

In this experiment, students investigate the importance of carbon dioxide to the reproductive growth of a marine microalga, Dunalliela sp. (Note that the directions are for teachers and that students protocol sheets will need to be created by teachers.)

Citizen scientist Anya, an indigenous Siberian girl, witnesses the changes in her community as a result of climate change after working with Woods Hole scientist Max Holmes' research team aboard her father's ship. She gets involved in collecting water samples to learn, and teach her schoolmates about, global warming.

In this activity learners work in pairs or small groups to apply knowledge of energy-wise habits to evaluate energy use in their school and make recommendations for improved efficiency. Students create and use an energy audit tool to collect data and present recommendations to their class. Further communication at the school and district level is encouraged.

A sequence of five short animated videos that explain the properties of carbon in relationship to global warming, narrated by Robert Krulwich from NPR.

A short video that discusses how changing climate is affecting the population of AdÃlie penguins.

This simulation allows students to explore the change in sea surface pH levels with increasing CO2 levels.

This teaching activity is an introduction to how ice cores from the cryosphere are used as indicators and record-keepers of climate change as well as how climate change will affect the cryosphere. Students learn through a guided web exercise how scientists analyze ice cores to learn about past climate conditions, how melting sea and land ice will contribute to sea level rise, and what areas of the world would be at risk if Antarctic and/or Greenland ice sheets were to melt away.

This is a classroom activity about the forcing mechanisms for the most recent cold period: the Little Ice Age (1350-1850). Students receive data about tree ring records, solar activity, and volcanic eruptions during this time period. By comparing and contrasting time intervals when tree growth was at a minimum, solar activity was low, and major volcanic eruptions occurred, they draw conclusions about possible natural causes of climate change and identify factors that may indicate climate change.

This teaching activity addresses environmental stresses on corals. Students assess coral bleaching using water temperature data from the NOAA National Data Buoy Center. Students learn about the habitat of corals, the stresses on coral populations, and the impact of increased sea surface temperatures on coral reefs. In a discussion section, the connection between coral bleaching and global warming is drawn.
