A short video on the causes of ocean acidification and its effects on marine ecosystems.

In this activity, students research various topics about ocean health, e.g. overfishing, habitat destruction, invasive species, climate change, pollution, and ocean acidification. An optional extension activity has them creating an aquatic biosphere in a bottle experiment in which they can manipulate variables.

This video features CU Boulder Professor Jeff Mitton and his research team, who study the effects of mountain pine beetle infestations on the forest ecology in the Rocky Mountains. They explain the pine beetle life cycle and how they attack trees. An outlook into the future is also provided.

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.

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.

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 video is the second of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. The video highlights the marine mammals and birds and how they depend on Arctic sea ice, as well as questions about how these animals will cope in the face of climate change.

In this video, scientist Dr. Susan Prichard discusses the impact of pine bark beetles on western forests. She explains how climate change, specifically rising temperatures, is exacerbating the problem.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

This video on phenology of plants and bees discusses the MODIS satellite finding that springtime greening is happening one half-day earlier each year and correlates this to bee pollination field studies.
