Fifth graders are introduced to the (hypothetical) scenario in which they are a team of EnviroTech engineers returning to the U.S. from a conference in Brasilia, Brazil. When their plane crashes deep in the Amazon forest, they work in groups to overcome various obstacles in their quest to reach help as quickly and safely as possible. They learn about the Amazon rainforest: location, climate, population, unique plants and animals, and threats to its existence.
