The North Bay Science Discovery Day (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. In 2025, there were 11,000 attendees (youth and their families), and 107 organizations providing more than 150 interactive hands-on STEM activities.

 

Mission
