Marine Environment Activity #3: Changing The Scene
1. The Natural History of Glacier Bay
Provide each group with a copy of the brochure map of Glacier Bay and the Marine Environment Glossary. Map of Glacier Bay National Park (Shows glacial retreat timeline) http://www.nps.gov/applications/parks/glba/ppMaps/ACF30C1.pdf
Distribute the Student Worksheet: Glacier Bay Over Time. This worksheet provides a note-taking guide for students as they read their assigned resource. The information they gather on this guide will be used in Step 2 of the activity.
2. An Annotated map of Glacier Bay
Briefly discuss the changes Glacier Bay has seen over time. At what point in its history do students think they would most like to visit the bay? Explain.
Invite students to choose one aspect of the history of the bay and illustrate it. They should write captions to explain their illustrations. Share these in a class display or short presentation.
3. Climate Change
4. The Future of Glacier Bay
They should discuss consequences for both the natural and human aspects of the area. What will happen to the glaciers? How will climate change? How might the changing climate affect the animals and plants that live in the area? What about the humans?
Following the discussion, divide students again into groups and divide the following topics among them to research on the Web. Each group should find and prepare 2-3 examples of their topic that could be put into a time capsule for Glacier Bay.
Each group should write a 1-2 page paper describing Glacier Bay as they think it would be in 50 years. Share the artifacts in class and discuss class predictions.
