The Case of the Wacky Water Cycle
Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.
Curated OER
The Sun as the Driving Force of the Water Cycle
Students study the water cycle and how the sun is an important factor. In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Environment: Water & Air
The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Desalination: Turning Salt Water into Fresh Water
How does San Francisco supply its citizens with enough water, even during a drought? Learn about reservoirs and why desalination could be a good solution with a reading passage about water conservation. After kids finish the...
Curated OER
Water: Access and Use
Students get a personal sense for another culture's way of doing things. Develop a list of sources for water. Practice using the scientific method. Examine means for conserving, or for generating, reliable sources of water.
Curated OER
Fresh or Salty?
Students explore water bodies on the planet Earth and their various uses and qualities. They examine several ways that engineers are working to maintain and conserve water sources and think about their role in water conservation....
