Meet National Geographic Emerging Explorer and Fellow, Dr. Enric Sala, who studies populations of organisms in pristine ecosystems. |
|
Instructions: - Have students read Earth’s Natural Treasures on Page 72 in the SE.
- Have students discuss the food pyramid or trophic models. Have them discuss and compare the trophic models on page 73 to the one on page 18 of a land ecosystem.
- Invite students to share other things they learned about the Hawaiian islands from their online research.

Discover what pristine and near-pristine ecosystems tell scientists about the functioning of an ecosystem and how science may guide ecosystem management and restoration. |
|
Instructions: - Have the students read the mission briefing article Rethinking the Trophic Model on pages 72-73 of the SE.
- Display the Inverted Pyramid of Consumers transparency and use the guiding questions on page 72-73 of the TE to lead an introductory discussion on the inverted trophic model.
- Have your students read pages 72-73 in the SE. As they read, have them record the 5 most important concepts from the reading and explain why the concept is important.

Reflect And Assess |
|
Instructions: - Use the discussion questions on pages 75-76 in the TE for a class discussion.
- Use the Extension exercise on page 73 of the TE for assessment.
