Exhibit at Discovery Days


Discovery Days are large-scale, highly visible, outdoor events where the Bay Area’s many STEM organizations connect with thousands of youth and adults. The result? Super-charged, super-fun celebrations of science! These FREE events feature hundreds of dynamic demonstrations, engaging experiments, and geeky games and draw families from all around the Bay Area. We seek exhibitors from all around the Bay to lead hands-on activities. At this point we are no longer accepting exhibitor registrations for the 2022 Festival.

To sign up for exhibitor updates, please email us at: [email protected]

Please note that we require all exhibitors and their employees and volunteers who work at Discovery Days to show proof of vaccination and wear masks while volunteering. We are following the guidelines of the City of San Francisco.
