The California State Science Fair is a science fair held annually at the California Science Center in Los Angeles.
The fair is fed by 28 regional science fairs, each of which is allocated a number of projects based on prior history of producing winning entries. The allocation in 2009 was 908 projects, an average of 24.7 projects per million population.
Awards are given in several categories at both junior (grades 6–8) and senior (grades 8–12) levels. The awards are posted shortly after the fair ends each spring. At the 2009 fair the major awards include the Patricia Beckman Project of the Year Award—David Zarrin of Redwood Middle School, Saratoga won the Junior Division ($5,000 award) and Anna K. Simpson of Patrick Henry Senior High School, San Diego won the Senior Division ($10,000). There are also many special awards sponsored by various organizations, some with cash prizes.
