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.
