Contaminants in the Water Cycle
Students will review the water cycle and investigate how a region's water supply can become contaminated. They will look at a list of the Environmental Protection Agency's maximum contaminant levels for drinking water, and sketch the water cycle of a fictitious town that is affected by several pollutants. Students will conclude by writing paragraphs explaining what a group of concerned citizens in this hypothetical town might do to improve the quality of its water supply.

Water Resources in Asia: Changes and Challenges
This lesson plan uses China's water issues as case studies to examine the delicate balance between using resources to improve the standard of living for citizens and preserving resources to protect natural biodiversity and environment. Students will conduct their own case studies on important water resources, such as the Aral Sea in Central Asia, to see how those resources have influenced the life cycles of countless generations of people and the flow of people, commerce, crops, and life in distinctly different regions in Asia.

Water Everywhere: Is there enough to drink?
Students analyze data for freshwater availability and consumption.  They will examine issues in shortage and pollution of freshwater sources.
