While the Earth is two-thirds water, less than three percent of that is freshwater. To further complicate the issue only a fraction of that water is available to be used to drink, for agriculture, power generation, manufacturing, or sanitation. Between this limited supply, a growing global population, and an increase in pollution assess to freshwater will be a defining issue for future generations.

Use these ideas for activities and projects in your classroom to teach your students about freshwater and its conservation.

Calculate Daily Water Use at School

Use this online tool to help start a school-wide campaign encouraging everyone to use less water. Get the word out with persuasive writing via posters or skits. Challenge your fellow students to a video public service announcement (PSA) contest. With drought conditions affecting many states, helping to save water in your community will be a step in the right direction.

Research Your Local Water Supply

How do the people who live upstream behave? Are they aware of those downstream, or do they contaminate the water? Do you do things that might pollute water for others? What are some steps your family could take to minimize its impact on air and water quality?
