The Tri-Valley Innovation Fair is the region’s can’t-miss, hands-on science program and is designed for curious minds of every age to explore, experiment, and discover together. Across 70+ interactive exhibits, live demonstrations, performances, and learning moments throughout the day, attendees can dive into everything from engineering challenges to creative tech, meeting the scientists, educators, students, and companies who bring big ideas to life right here in the Tri-Valley.
“The Tri-Valley Innovation Fair is more than a one-day celebration—it’s a cornerstone of Quest Science Center’s ongoing mission and our promise to keep building equitable access to high-quality, hands-on learning across the Tri-Valley and beyond year after year. As the presenting organization”, says Michael Mosby, Interim Executive Director of Quest, “we’re thrilled to welcome thousands of regional residents to explore, enjoy immersive exhibits, and connect with the people and ideas shaping what’s next for the Tri-Valley.
Powered by Quest Science Center and made possible through sponsors, volunteers, and community collaboration, the Tri-Valley Innovation Fair continues to grow as a shared community tradition—and a welcoming on-ramp for anyone who wants to support STEM learning and opportunity in the region.
