In this activity, students research changes to the environment in the Arctic/Bering Sea over time using oral and photographic histories. Developed for Alaska Native students, this activity can be customized for other regions.

This lesson guides a student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

This sequence of activities using real-world data to explain the importance of coral reefs and the relationship of coral reef health to the surrounding environment. Unit includes five activities.

This is a short experiment to demonstrate the concept of thermal expansion of water when heated, as an analogy to thermal expansion of oceans due to global warming.

This lesson plan has students working in small groups to research the Mountain Pine Beetle in Colorado and other inter-mountain Western states. Students identify the factors that control pine beetle population and research how warmer winters and decreasing spring snowpack allow the population of pine beetles to expand.

In this activity, students learn about sea ice extent in both polar regions (Arctic and Antarctic). They start out by forming a hypothesis on the variability of sea ice, testing the hypothesis by graphing real data from a recent 3-year period to learn about seasonal variations and over a 25-year period to learn about longer-term trends, and finish with a discussion of their results and predictions.

This activity relates water temperature to fishery health within inland freshwater watersheds as a way to explore how environmental factors of an ecosystem affect the organisms that use those ecosystems as important habitat.

In this EarthLabs activity, learners explore the concepts of coral bleaching, bleaching hot spots and degree-heating weeks. Using data products from NOAA's Coral Reef Watch, students identify bleaching hot spots and degree-heating weeks around the globe as well as in the Florida Keys' Sombrero Reef to determine the impact higher-than-normal sea surface temperatures have on coral reefs.

In this activity students research the inter-dependencies among plants and animals in an ecosystem and explore how climate change might affect those inter-dependencies and the ecosystem as a whole.

In this activity, students engage in a simulation of the international negotiation process in order to convey how the international community is responding to climate change. Participants learn firsthand about the interests of different countries and the range of policy responses to mitigate future climate change.
