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.

Megan Sherman, Early Childhood Educator

Megan Sherman is thrilled to be working with Proton Preschool. Her love for all things science stemmed from spending many summers at science camps while growing up in New Jersey. One thing she loves about the Pacific Northwest and Seattle is its proximity to all things nature: the mountains, the forest and the Puget Sound! She especially enjoys spending time in Discovery Park. Megan was an educator at both the Seattle Aquarium and IslandWood: A School in the Woods, and has also been fortunate to develop programming at the Kids Discovery Science Museum and to be an assistant preschool teacher at Epiphany School. A recent recipient of a master’s of education from UW — Megan is beyond excited to share her passion for science at Pacific Science Center!
