Grades 6–8 Overview Water not only sustains life on Earth, it is also a critical source of power in San Francisco and around the world. By exploring the ways communities obtain and use water and power, students see the impact of personal and collective actions on people and other living beings. They also learn how diversifying sources, using water and power efficiently, protecting watersheds, and keeping water clean all help to increase the resiliency of communities while safeguarding the environment.
