About Cal Water H2O Challenge's Classroom Challenge

Cal Water H2O Challenge's Classroom Challenge is a project-based, environmentally-focused competition for classrooms, grades 4-6. Designed in conjunction with NAAEE, the WestEd K-12 Alliance, and Cal Water, and aligned with the Common Core State Standards and complementary to the Next Generation Science Standards, the Classroom Challenge offers a unique opportunity for upper elementary teachers to facilitate their students’ learning of standards-based content, while developing the core understanding of environmental principles necessary to becoming science-literate citizens.

The Cal Water H2O Challenge, currently in its sixth year, began as a classroom competition in 2014. To date 250 classrooms have participated in the Classroom Challenge. We are honored and privileged to continue to offer this experience to fourth-sixth grade classrooms in the Cal Water Service area, inviting them to develop and implement solutions for local water issues. Additionally the Classroom Challenge will now open for the first time to school-based clubs as well.
