Sponsors
Join us for the 13th anniversary of the North Bay Science Discovery Day (NBSDD)! The event reaches over 10,000 youth and their families, providing over 120 hands-on activities provided by more than 75 exhibitors. The NBSDD is a powerful platform to foster a love for science, technology, engineering, and mathematics in the next generation. The NBSDD is brought to life by a dedicated volunteer committee of science enthusiasts, in partnership with the University of California 4-H Youth Development Program.
Mission
Spark young people’s wonder and curiosity about STEM; strengthen the San Francisco North Bay’s STEM learning ecosystem; and connect the STEM industry, education, and public sectors to deepen and sustain young people’s STEM learning.
Why Sponsor?
Thanks to the generous support of sponsors like you, the NBSDD remains a free event for all attendees and exhibitors! By joining our network of dedicated supporters, you’ll showcase your commitment to STEM education while connecting with diverse audiences and demonstrating your passion for science and innovation. By contributing, you help create an inclusive environment where families of all socioeconomic backgrounds can share in the excitement of STEM. Together, we can build a stronger North Bay community, connecting schools, organizations, and families through a shared passion for science.
