Learn About Water!
The U.S. Geological Survey (USGS) and the Food and Agriculture Organization of the United Nations (FAO) have teamed up to create a water-cycle diagram for schools. It is available in over 20 languages and also in an interactive version made for online viewing and investigating.
This diagram is a small part of USGS's Water Science School, where anyone of any age can learn all about water.
