The Watershed Connection – reducing pollution and protecting San Diego Bay

The Resource Conservation District of Greater San Diego County – in partnership with the Port of San Diego – offers the Watershed Connection, a free watershed education program available to all second through sixth grade students at schools located within the San Diego Bay Watershed.

The program includes a one-hour, in-class presentation providing students a hands-on opportunity to learn about their environment. Participants are introduced to the connection between land, water, and human actions, as well as common storm water pollutants in San Diego. The presentation supports Next Generation Science Standards and CA Science Standards.  

May contain: turtle, animal, sea life, reptile, sea turtle, and tortoise

Program overview

During the presentation an RCD educator will "pollute" a three-dimensional watershed model and students will make predictions about how pollution might affect the model. Students then observe a simulated rainstorm and are invited to draw conclusions about the causes and effects of pollution. Throughout the presentation participants are encouraged to explore methods for pollution prevention and to share in a conversation about human impact on natural resources. Students learn simple actions we all can take to prevent pollution.
