At this site from the U.S. Geological Survey you can find out what makes rain such a valuable resource. Included is a chart that tells how much rain different cities in the United States receive. Click Home to access the site in Spanish.

Student groups create personal rain gardens planted with native species to provide a green infrastructure and low-impact development technology solution for areas with poor drainage that often flood during storm events.

In this lab, students investigate whether the rate of water falling (rain) affects the amount of erosion (soil movement). This experiment could lead to further questions: how does grass or rocks effect soil erosion, does erosion lead to...

Explains the different stages in the water cycle while covering important vocabulary. Supported by lots of visuals and includes a good water cycle animation.

A collection of resources--pictures, maps, data, glossary--about water and the water cycle.

When it rains, some of the rainwater soaks into the ground, and part of it flows over the ground and directly into creeks, streams, or rivers. This water that runs off into the river is called runoff, or sometimes stormwater runoff....

Lake Mattamuskeet-so named by Algonquian Indians-is North Carolina's largest natural lake. The ancient body of water has not escaped man's intervention. Originally, Mattamuskeet was a shallow, self-contained lake without creeks or rivers...

Check out this simple overview of the water cycle and learn how to build a model of the water cycle.

This is a very brief overview of the water cycle, but it does have a nice graphical representation.

[Free Registration/Login Required] This is a science flipchart that reviews the stages of the water cycle and also ways in which the water cycle affects weather such as hurricanes and tornadoes.

See how rainwater and snow melt flows from high areas to low areas which ultimately results in Earth's groundwater.

In this activity, students investigate a large watershed, look for sources of pollution in the watershed, and study the impacts of a rain storm on a watershed and estuary, without going on a field trip. Students investigate the nature of...

Animation and text explain the water--or hydrologic--cycle, which is the process that water undergoes in nature.
