The 5th annual Discovery Day at AT&T Park is Saturday 11/7/15. There will hundreds of hands-on activities, opportunities to meet local scientists and engineers, and plenty of fun and educational entertainment. The entire ballpark is packed to the rafters with science content: on the field, at every entry/exit, and every level of the ballpark. Get ready to unleash your inner scientist.

When: Due to popular demand, we are extending the hours of this event to 10AM-4PM!

Suggested Age: Families with kids 0-14

Cost: FREE!*

* We will be releasing a limited number of early access tickets on October 9th for families.

What to Expect in 2015

  • 150 Exhibits and Activities


    Experience over 150 hands-on exhibits and activities from leading science and technology organizations from across the Bay Area. Universities, science museums, research labs, after school organizations, and local companies join forces for an unprecedented opportunity to meet scientists and engineers. Topics include health & medicine, engineering, technology, biotechnology, climate science, and so much more. This year, every exhibit will be framed as investigative questions to encourage explorations and curiosity that we hope will continue throughout the school year.

  • Chevron STEM Zone


    Join us on the field and the fun, interactive activities that provide an inside-look at the science of sports, train like an astronaut, explore robotics, and pick up a family science guide.

  • Life Science Alley


    Experience the best of biotech with a dozen of the Bay Area’s leading life science companies. Extract your DNA, explore your genes, and meet the scientists engineering the next cure.

  • Robot Zoo brought to you by the Bosch Family Foundation


    Willie Mays Plaza will be overrun by robots of all shapes and sizes. Interact with High School robotics teams, startup companies, and cutting edge research robots. This area is run in collaboration with Silicon Valley Robotics
