This well-designed website was developed by the National Oceanic and Atmospheric Administration's National Ocean Service (NOS) to educate high school students and others about coral reefs. The site contains the following three main components: a tutorial providing an overview of coral reefs; two downloadable lesson plans; and links to a variety of online information about coral reefs from the National Oceanic and Atmospheric Administration. The tutorial contains 11 concise sections about topics such as: threats to coral reefs, coral reef formation, stony corals, coral diseases, and coral reef protection. The two lesson plans focus on coral reef bleaching, and coral reef management. The plans include National Science Education Standards, Learning Objectives, Teaching Time, Learning Procedures, Background Information, Resources, and more.
