Hydrologic cycle students will demonstrate knowledge of basic

science concepts of earth science through direct experience, including an understanding of: (a) concepts related to everyday life through…patterns and how they repeat, and cycles; (b) how the basic needs of organisms are met. Students will have the opportunity to identify the various ways water moves throughout the earth as part of the water cycle. This is a great hands-on activity that students will be excited about.

Objectives

Identify sources of fresh water available for consumption

Understand the need for water conservation due to the limited fresh water supply

Explore strategies for conserving water at homeCompare the benefits and drawbacks of using

different water management techniques, particularly dams

Importance of conserving water and techniques for reducing water use at home

OverviewAlthough over 70% of Earth's surface is covered

with water, less than 1% of this water is available for human consumption. In this lesson, students study the availability of water on Earth and discuss methods that can be used to purify and conserve this critical resource. They also assess how much water they and their families typically use, and think about ways to reduce their water usage. Finally, students explore different techniques being employed for water management around the world, including the use of dams to create reservoirs.

techniques for reducing water use at home Take shorter showers. One way to cut down on water use is to turn off the shower after

soaping up, then turn it back on to rinse. A four-minute shower uses approximately 20 to 40 gallons of water.

Turn off the water after you wet your toothbrush There is no need to keep the water running while brushing your

teeth. Just wet your brush and fill a glass for mouth rinsing. A list for parents 25 ways to conserve water in the home and yard http://eartheasy.com/live_water_saving.htm
