Open House

We will be holding two Open House sessions this fall for anyone who would like more information about the Challenge or who may be on the fence about participation. Come meet our Teacher Ambassadors, hear about how they have engaged with the Challenge in the past, and have your questions and concerns addressed. What’s more, if you register at the Open House you will be entered in a drawing for a $250 grant! 

Open House sessions will be held on Wednesday November 16 and Wednesday January 11, 4:15pm-5:15pm PST.

Project Grants

Are you looking for funding for your Classroom Challenge project? DoGoodery also offers $500 grants that will be distributed by random selection to registrants that register by the early registration deadline of December 31, 2022. Any registrant that accepts these funds must commit to submitting a project by the deadline of February 28, 2023.

If you have already received a $100 grant through the Cal Water H2O Challenge Grants Program during this program year, then you will only be eligible for an addition $400 in grant funding through this early registration grant process.

Additional grant opportunities, not directly offered by Cal Water, can be found in the Grants and Water Links section.
