Physics for the 21st Century
This course covers a broad scale, from sub-atomic particle physics, through atomic and molecular physics, to cosmology. The video programs feature 22 case studies of researchers from leading research labs and universities who are breaking new ground in their fields.
Through fieldwork and lab work, archaeologists have been piecing together what happened to bring about the collapse of Copán, once a thriving center of Maya civilization. In this activity, you'll be following in the steps of the archaeologists who studied Copán, looking for clues to how it collapsed. You'll be trying to answer two questions:
1. Why did Copán collapse?
2. Was the end a gradual decline or a rapid fall?
