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.
“WOW! What incredible and engaging lessons to do with my students. They loved this opportunity to be scientists, explore and think about the food they eat, and I loved the ways that they began to model. I am so excited about these lessons and cannot wait to share them with my coworkers.”
“There is something for all different kinds of learners. We are moving spaces, drawing, talking in big and small groups, writing. Some of my kiddos who would have been disengaged quite possibly the entire time were engaged in at least two or more parts of this lesson.”
“My kids have said, ‘Oh good, I like doing this,’ when we were starting the lesson each day. It’s a great topic. I also think it has made them more curious and do their own research.”
“The message that there are solutions to help us combat climate change and that people are working together to solve problems helped students stay in a place of curiosity; they didn’t show anxiety over the content.”
“I have learned ways to improve my teaching, and I have been at this for 38 years. The students are gaining a deeper understanding of what climate change is: what causes climate change, and the impact of climate change on crop yield.”
“I heard comments like, ‘I didn’t realize how much climate change affects my community,’ and, ‘This project made me think about what I can do to help.'”
“This lesson brought in cultural stories from the original people who inhabited California. This is a perspective that is not often taught in science. I think that the kids liked having science be a little less facts and figures and more story.”
“What I find interesting is that students are discussing the material outside of class time. I heard students discussing the ideas before class in the hallways and even during lunch periods.”
“Every lesson was so thoroughly designed, the case study design book was beautifully organized, and it helped to give my class a real-life understanding of how college/graduate-level academic research works. Being able to connect their research back to environmental issues they actually experience was simply icing on the cake. Well done!”
“They’ve never thought about stuff like this before, and now they’re sharing it. One girl said this was the only class that she went home and talked to her parents about.”
“I am so amazed and impressed by the depth of resources that you embedded in the teacher guide. This is really well put together.”
“Using the maps and seeing things like schools and how close they are to hazards is really cool. They may not be super connected personally, but they can put themselves in the shoes of other kids and try to relate. I know it’s working because I have a kid that just watches Netflix all day, every day and he pulled out his earbud and participated!”
