NOAA Ocean Service Education: Keeping Watch on Coral Reefs
http://oceanservice.noaa.gov/education/lessons/keep_watch.html


Students investigate the effects of climate change on oceans. The lesson introduces students to coral reefs and improves their understanding of why these systems are important, how they are threatened, and what can be done to protect and restore these unique and valuable ecosystems. It also introduces students to data available from remote-sensing tools that can be used by anyone to study the Earth's ocean.
