In this activity, students examine hydra, a fresh-water relative of coral, under a microscope to observe feeding behavior and identify stinging cells that are characteristic of corals. They also learn more about the individual animals that make up coral reefs and construct simple models of coral polyp anatomy and feeding behavior.

During this lab, students learn about the life cycle of corals, including how they grow and reproduce. Students consider the chemistry of seawater and the importance of the symbiotic relationship between corals and zooxanthellae in the formation of coral reefs. They blow CO2 through calcium hydroxide (limewater) to model how respiration assists coral in precipitating calcium carbonate. Students also build on the coral polyp models they made in Lab 2 to demonstrate coral growth, reproduction, and reef formation.
