http://www.learner.org/interactives/collapse/
From Annenberg Media, Collapse: Why do Civilizations Fall is an online exploration that features the collapse of four ancient civilizations: The Maya, Mesopotamia, Chaco Canyon, and Mali & Songhai. You’ll learn what happens when a society collapses and how archaeologists find and interpret evidence. Interactive features allow students to visit the Maya city of Copan and search for clues to its collapse or try their hands at “garbage-ology” and study what trash can say about a society.
