Tables and maps provide information on quantity and quality issues including data on access to safe drinking water; waterborne disease outbreaks; desalination capacity; as well as hydroelectric capacity and production. There is also a unique chronology documenting the historical ... Full description.

As part of its Water Science for Schools site, the US Geological Survey defines industrial water use and includes several tables and maps showing where and how industry uses water. Students and teachers can look at their state and see 1990 data for how much ground water and how much surface water is used in industry as well as how much of that water is fresh or saline.

In this activity, students explore the influences of different parameters on the environmental quality of a river system. They will run a computer model of a river system, interpret graphs, and adjust model parameters such as wind speed, sewage load, and other variables to determine their effects on water quality. For teachers, there are additional background materials, teaching tips, evaluation methods, ... Full description.

This lesson is designed to help students gain knowledge in using the MY NASA DATA Live Access Server (LAS) to specify and download a microset of data, then to use the data to determine the seasonal cloud coverage and the occurrence of different cloud types, by percent, in the North Carolina (or their local area). Students will identify different cloud types and determine their seasonality. They will ... Full description.

The depletion of the ozone layer is recognized as one of the Earth's most important environmental issues. The Antarctic ozone hole is recognized as one of the most striking indicators of ozone depletion. The location of the ozone hole is generally confined to the latitudes over Antarctica, although there are occasions when the ozone hole can move over lower latitudes locations such as South America. ...

This module offers students the opportunity to analyze and qualitatively compare the inorganic ion content and pH of different sources of local drinking water. The students collect, organize, graph, and analyze quantitative data showing the uses of groundwater in their state. They will read, summarize, and discuss news articles about the emerging impact of merchant power plants on groundwater resources. ... Full description.

Students investigate the importance of water historically and in their daily lives and examine the nature of water as a limited resource. Working in groups, they will list the various uses of water, discuss why water is a limited resource, research technological systems that are intended to use water as productively as possible, and create "How It Works" posters for presentation to the class. The ... Full description.

The Chesapeake Bay is the largest estuary in the US. Eleven rivers empty into the bay creating the Chesapeake Bay Watershed. From urban areas and cultivated fields in which wetlands were not preserved, runoff can run into the rivers unfiltered. This runoff can include nutrients that can cause uncontrolled growth of an abundance of algae which can eventually increase the turbidity of the river, not ... Full description.
