In this lesson, from Xpeditions, students learn about tiger sharks through Web sites such as National Geographic's "Filming Tiger Sharks" site. Students draw food chains and conduct a simulation to see the relationship between members of the Shark Bay ecosystem and learn why the tiger shark is considered a keystone species. They conclude by writing paragraphs describing these relationships.
