Proton Preschool

Thank you very much for your interest in Proton Preschool; Pacific Science Center is no longer running this particular program. We invite you to experience our other preschool aged programs, including our nature-based Polliwog Preschool and Wetland Waddlers at our Mercer Slough location in Bellevue. Pacific Science Center also offers a daily preschool planetarium show, and PreK Summer camp experiences at several locations (summer 2018 information).
