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. Brought to you in conjunction with DoGoodery, the WestEd K-12 Alliance, and Cal Water, and in partnership with the California Association of Science Educators, the Classroom Challenge is aligned with the Common Core State Standards and complementary to the Next Generation Science Standards, and includes recommendations on how it can be integrated within your own classroom, while meeting curriculum goals. Through this integration, 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 eighth year, began as a classroom competition in 2014. To date nearly 300 classrooms have participated in the Classroom Challenge. We are honored and privileged to continue to offer this experience to fourth-sixth grade classrooms in a Cal Water service area, inviting them to develop and implement solutions for local water issues. Additionally the Classroom Challenge for the third year in a row welcomes school-based clubs to participate as well.


Learning Styles:

The Classroom Challenge is evolving to meet your changing needs and to help you bring a relevant, meaningful, project based learning opportunity to your students that transcends distance learning. Whether teaching remotely, in-person, or through a hybrid model, our new expert Teacher Ambassadors and advisors have developed a clear pathway to engage your students in real-world inquiry while helping you meet your curriculum goals.



And we're here for you! We will now be offering office hours to help you and your class meet your goals. Through the support of our teacher ambassadors, we will be offering virtual meetings along with an updated handbook, new video guides, and additional resources to make your Classroom Challenge an amazing and smooth experience!


Design Over Implementation:

Additionally, like last year, understanding the hurdles of distance learning, and the need for an equitable, fair competition, this year's Classroom Challenge shall focus on designing solutions to care for water. What does that mean for you? Judges will not be seeking fully implemented projects, but looking for complete designs that have been tested and refined, with the aim to address a local water issue. Perhaps your design will be a way to keep garbage out of the storm drains and prevent it from traveling to the ocean. Maybe your students will design a way to clean up a local creek or waterway. Your students may even create an engineering design for testing or cleaning water on campus. Whatever your students choose to do, you shall have our support, and we look forward to seeing their ideas!
