Proton Preschool

Thinker Kids

Proton Preschool is a STEM-based school year program of Pacific Science Center, held right under the arches in downtown Seattle. The program is play-based and for children ages 3 to 5. At Proton Preschool, science is used as the ideal catalyst for discovery and stimulation. Weekly themes and daily activities are designed to meet the developmental needs of early learners, while inspiring curiosity, cultivating a love for learning, and teaching basic science concepts – all while utilizing the incredible resources that Pacific Science Center has to offer.

Learning Philosophy

Proton Preschool leverages science to facilitate powerful learning experiences through hands-on, play-based activities and investigations. We utilize scientific inquiry to develop children’s cognitive, social and emotional skills and provide them with engaging experiences designed to stimulate rich conversations with their surroundings and with each other. Our emphasis on cognitive and social experiences enhances each child’s lifelong learning skills while fostering respect for the world around them.
