|Caution: Do Not Bleach!|
In this lesson, students will investigate the importance of coral reefs to the Earth as a whole and learn some possible explanations for the phenomenon known as "coral bleaching". They should be able to identify ways that coral reefs benefit human beings, identify major threats to reefs and discuss how they might be reduced or eliminated, describe the Coral Reef Early Warning System, and discuss why corals might expel their zooxanthellae (symbiotic algae) when under stress.
