San Ysidro STEM Fair

The Annual San Ysidro STEM Fair is a co-created celebration of curiosity, community, and opportunity. Each spring, families, students, schools, and partners come together to lower barriers and open doors to science, technology, engineering, and math (STEM) education and careers. 

Chaired by the Fleet Science Center, the San Ysidro STEM Committee is proud to mark the 5th anniversary of this free, equity-centered, family fair. An event built with the community, for the community. 

In 2025, more than 45 exhibitors inspired students and families with: 

• Learning demonstrations led by San Ysidro District‘s Sci Phy program teachers
• Robotics demos led by San Ysidro High School’s Cougarbots team
• Physiology demos led by San Ysidro High School‘s MEDICS Club
• Hands-on learning with local scientists and STEM career role models
