Please help us make the California Science and Engineering Fair (CSEF) possible for the outstanding young scientists and engineers from affiliated fairs throughout the State of California. They rely on your generosity to enable the fair to be held where they may meet each other in camaraderie and competition, make new friends with similar interests, and for those with the best projects, move on to the national competitions of (for grades 6-8) the Thermo-Fisher Scientific Junior Innovators Challenge and (for grades 9-12) the Regeneron International Science and Engineering Fair (ISEF).
