Volcan Mountain Watershed Round Robin (1 hour)

Watershed Model (30 minutes)

The watershed model demonstrates that Volcan Mountain feeds four large watersheds in San Diego County, including the San Dieguito, San Diego, San Luis Rey and Anza-Borrego watersheds. It also demonstrates how the canyons and ridges of the mountains funnel the water from natural springs and rainstorms downhill to the valleys below and out to the ocean. It gives an overall understanding of how watersheds work and filters pollutants that occur upstream.

Water Quality Testing (30 minutes)

Students will learn about different factors that affect water quality and the health of our watershed. Working in small groups, students will collect and test water samples for dissolved oxygen, nitrates, phosphates and pH and rank the water quality on site.
