Mercer Slough Environmental Education Center
At Polliwog Preschool, nature ignites curiosity as children explore the living classroom of Mercer Slough Environmental Education Center in Bellevue. Polliwog Preschool is a school-year program for children ages 3-6 that builds a foundation for a lifelong love of science, nature, and learning.
Parents love Polliwog because of our commitment to hands-on learning, emphasis on social and emotional development, and small teacher-child ratio. Kids love us for the variety of fun and exciting ways we explore the world around us. As one of King County’s oldest nature preschools, we’ve built a reputation for excellence over the past eight years.
