Save the Date for the 2027 Tri-Valley Innovation Fair!

Join us for a day of hands-on science, engineering, technology, and creativity at Quest Science Center’s Tri-Valley Innovation Fair, the region’s largest science and technology fair!

We’re expanding into an additional exhibitor building in 2027, creating more room to explore, connect, and discover together. Bring your family, invite your friends, and follow your curiosity as you meet people and organizations sharing ideas and innovations from across our community.

Whether you love building, experimenting, asking questions, or trying something new, there’s a place for your curiosity at the Fair!

Mark your calendar and check back for registration information, participating exhibitors, and more event details as plans take shape.

Watch highlights from the 2026 Tri-Valley Innovation Fair, when more than 70 exhibits brought science, engineering, and technology to life through hands-on activities, conversations, and shared discoveries.
