7th Grade

Students investigate the sinking of California’s Central Valley, a phenomenon otherwise known as land subsidence. Using the phenomenon as an anchoring point, students explore California’s water crisis and its intersection with historical colonialism, groundwater mechanics, and environmental justice through an engaging, character-driven narrative. The unit begins with Jolfy, a cyborg coyote from the future, who alerts students that the Central Valley is sinking. Along the way, students meet other characters who provide key insights: historian Yoimut, hydrogeologist Carl, climate scientist Mariah, and farmworker and local council member Jaden.

Students explore the Central Valley’s transformation from a water-rich ecosystem under Indigenous stewardship to its current state, shaped by colonization, industrial agriculture, and irrigation networks. Students investigate how aquifers work, how excessive pumping and climate change deplete groundwater, and how this impacts ecosystems and frontline communities. Students also examine solutions, such as managed aquifer recharge, water conservation, and climate action. The unit fosters critical thinking and empowers students to envision sustainable solutions for their communities.
