Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Pupils describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.

Students study the water cycle and how the sun is an important factor.  In this water cycle lesson plan students investigate how to desalinate water and explore the different densities of fresh versus saltwater.
