This report from the U.S. Geological Survey uses illustrations to show how water moves through an aquifier and also how water is obtained from the ground.

Drinking water comes from many different sources, including surface water and groundwater. Environmental engineers analyze the physical properties of groundwater to predict how and where surface contaminants will travel. For this lesson,...

In this science activity, students investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the water...

Students gain a basic understanding of the properties of media- soil, sand, compost, gravel- and how these materials affect the movement of water (infiltration/percolation) into and below the surface of the ground.

Instructional module focusing on the hydrological cycle. Discussion includes the movement of water through the different reservoirs on earth and its impact on climate and weather patterns. Site also includes an interactive practice quiz...

Learn about the movement of water from Earth's surface to the atmosphere with this site. Site describes the water cycle in words and with a diagram. Also explored on the page is the distribution of Earth's global water supply.
