Students will explore saltwater environments -- from shorelines to coral reefs -- and learn about the fish, plants, mammals and insects that depend on each other for survival in this aquatic biome. Examine concepts such as salinity and currents, and find out about the three major life zones found in ocean waters. A fun, hands-on experiment allows students to discover how brine shrimp have adapted to changes in salt concentration, while a visit with a marine biologist on the Chesapeake Bay examines the fascinating life cycle of the blue crab.
