California State Science Fair

The California State Science Fair is the final science fair of the academic year for students throughout the State of California in grades 6 - 12, serving California's future scientists since 1952. It is hosted by the California Science Center (formerly, the California Museum of Science and Industry).

The 64th annual California State Science Fair will be held in the California Science Center on May 18-19, 2015. That's only 78 days away! This year we expect about 1000 participants from 400 schools throughout the State who will meet in competition for awards totaling $50,000.

Special thanks go to the following organizations for their generous donations and volunteer efforts.
