Control the U.S. Debt!
Neither the president nor Congress appears to be near a solution on how to control the U.S. debt. Use this <a href="http://www.learner.org/series/econusa/interactivelabs/control-the-us-debt/">interactive</a> to show them how to do it.
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?
