3. Create a Web page for Glacier Bay
- After the students have completed their reading, ask them to discuss the information on Dungeness Crabs. Does the Glacier Bay site have a page of information on their Dungeness crab population?
- Give the students time to explore the Glacier Bay Web site to look for any information they can find on these crabs. Instruct them to organize any sites they find as "readable" by the general public or "readable" by scientists.
- Divide students into small groups. Challenge them to create the Web page or PowerPoint slide show on the Dungeness Crabs of Glacier Bay that they believe would enhance the Glacier Bay site.
- Instruct them to include on their site:
- What crabs eat at each stage of their development
- How crabs cope with environmental conditions and changes, predators, and scavenging
- What the crabs' favored environment is in Glacier Bay at each stage of their development
- What resources they will cite on their presentation or Web page
- Share these in a bulletin board display.
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).
