This model was so popular and effective at teaching people about runoff pollution that, over the next year, I ended up overseeing the construction of two more. The second model was built by a group of at-risk high school students who came on a field trip to see the Morro Bay model. I told them that kids had built it and showed them our photo album of the construction. They pushed hard to build one of their own, enthusiastically writing letters to support a small grant that we applied for. We built a third model at an elementary school.

Teachers at the school now use the model to teach about watersheds, and kids from the 4-H Science Clubs give demonstrations about runoff pollution to community groups. 2156 Sierra Way, Suite C, San Luis Obispo, CA 93401.
