If a civilization as powerful and technologically advanced during its time as the Maya could disappear, can the same tragic outcome befall the United States? In this lesson, students work in teams to research the ancient Mayan civilization, specifically the circumstances of its demise. Student teams prepare a report of their findings and recommend ways the United States can avoid a similar fall. Students are provided with background information, detailed instructions, on-line resources, and reflection questions. The teacher's notes describe the unit's purpose. (BT)
