Un Mar de Colores · Bonita, CA
Free Watershed Education for Bonita Youth & Families
NGSS-aligned curriculum for Chula Vista Elementary / Sweetwater Union teachers seeking real field science, not textbook supplements.
Un Mar de Colores's Watershed Explorers program brings Bonita youth into the full watershed-to-ocean story of San Diego County. Day trips and overnight summer cohorts trace mountain streams from Cuyamaca State Park to the coast, returning to Imperial Beach (10 miles) and Coronado Central (11 miles) (closest breaks to Bonita) for ocean-based lessons. We partner with Chula Vista Elementary / Sweetwater Union and community organizations including Bonita-Sunnyside Library and Sweetwater Union High School District to recruit from Sunnyside Elementary, Bonita Vista Middle. Every program integrates the Tijuana River watershed case study — the only cross-border river in Southern California.
