3. Create a Web page for Glacier Bay
Invite interested students to research the Internet or the local library to find pictures of each of the marine ecosystems they read about. They could then design an information poster or bulletin board, called A Crab's World, showing the different habitats of a crab through its lifetime. The artwork should be as accurate as possible and contain as many of the known denizens of these zones. Students can then annotate A Crab's World, sharing information about the ecosystems they are depicting and the crab's life stage and role(s).
