	CONTENT: Water Science for Schools from the U.S.Geological Survey (USGS) provides resources and information to teachers and students on just about anything you ever wanted to know about water. It includes maps, pictures, a data library, and more.
	SITE DESIGN: This well designed site is available in both Spanish and English. The main page offers a menu of the main sections of the site. Additionally there is a link to the main water topics that gives descriptions of the sections and a site map (NavGuide) that lists all the enormous amount of content in an index. Clicking on the NavGuide may be the easiest way to find the information you need.
	REVIEW: Water Science for Schools examines a wealth of water topics such as water properties, how much water is there on earth and where, how water quality and stream flow are measured, the water and water-use cycles, national maps showing how water is used by state, surface and ground water, pesticides in ground water, aquifers, and glaciers and icecaps. Other features include an activity center, galleries of maps, pictures, and data as well as a glossary of water terms, links to other water-related sites, and a certificate of completion. A new addition to the site is The Water Cycle, “The most comprehensive Web site about the water cycle anywhere, with a diagram available over 50 languages.” The interactive diagram gives users more information on each of the topics included in the water cycle. Included is a text menu of topics at the bottom of the page, a printer friendly version of the diagram (with or without text) and a diagram where students have to place the terms.
