We believe that through experiments, tinkering, and construction activities children and youth will gain the confidence to grow academically, as they also develop a genuine interest in the world around them.

Our two SF neighborhood science centers offer programs to 11,000 underserved students and their families throughout the year, and offer 1,400 workshops annually with 41 public schools and dozens of community partner groups.
