AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms. At present, the data for the marine algae, particularly seaweeds, are the most complete. For convenience, we have included the sea-grasses even though they are flowering plants.

This video segment from the Race to Save the Planet teaching module "Saving the Diversity of Life" describes the ecological value of tropical rainforests and explores some of the causes of their destruction.

Relevant material from MIT's introductory courses to support students as they study and educators as they teach the AP Biology curriculum.

One of the most rewarding and challenging aspects of teaching an advanced placement environmental science course is finding enriching field and lab activities for your students. These labs have been developed by an experienced team of environmental science educators in partnership with the Environmental Literacy Council. Each lab has been the subject of an extensive peer review by a number of experienced environmental science educators. The content of this initial collection is varied, and APES teachers and students in different areas around the country should be able to complete each of the labs. These initial labs are not typical cookbook variety. They each contain an inquiry-based component. Over time, additional labs and tools for new and experienced teachers will be added to the collection.

In this video segment adapted from NOVA, animations are used to illustrate how change in the tilt of Earth's axis produces dramatic climate change over thousands of years.

This is a two-part teaching unit about the controversy among conservationists over a proposal to turn part of Yosemite National Park into a dam to furnish water to San Francisco. The first part explores the history of the conservation movement in general, while the second links to primary records, such as Congressional debates, of Hetch Hetchy itself.

This site includes simulations of more than 40 phenomena: sea ice and CO2, climate change (230-year period), clouds and precipitation, coral reef evolution (starting 21,000 years ago), universal fire shape, fire twirl and burst behavior, tornadoes, thunderstorms, typhoons, El Niño events, greenhouse gases and sulfate aerosols, polar vortex breakdown, CO2 and temperature, CFCs in the ocean, cloud evolution (7-day period), daily weather in the U.S., and more.
