The Annenberg Media project continues to bring interesting and engaging educational materials to teachers and students, and the ball keeps on rolling with this particular feature. The ecology lab feature here is designed to be used in conjunction with "The Habitable Planet" series, which is also available on the site. Teachers and others will note that the site includes an ecology simulator, and visitors can toggle the various settings to learn how the addition or removal of different species will affect their self-designed ecosystem. The simulator is fairly easy to understand, and there's a "HELP" section designed to provide assistance. Additionally, the site also includes a glossary of relevant ecosystem terms, videos, and an online textbook.
