In addition to the sample lessons included in our handbooks, The Cal Water H2O Challenge offers on-site and online support to help teachers as they move through their project-based instruction. This support is made possible by the dedication of the WestEd K-12 Alliance

The K-12 Alliance will contact registered teachers to offer their assistance. Registered teachers are also welcome to contact us to request support as needed.
