Explore kelp forests and learn how giant kelp create a habitat for many, many organisms! Observe and study these plants and animals and their relationships. Compare different species to learn about the many shapes and adaptations of algae and learn how people use these seaweeds. Study an amazing diversity of invertebrates and fish, and learn how they feed and live. Learn about the absorption of light in water, and what that means for animals in the ocean. Through games and role-playing, experience the impact of over fishing vs. managed fisheries. Take a virtual dive in a kelp forest, and then in a shore-based field inquiry, collect data to answer your own questions about algae and its adaptations and distribution.
