The mission of Portland Children's Museum was to create transformative learning experiences through the arts and sciences. The museum used cognitive science and child development research to inform environments and programs that promoted healthy cognitive, social, emotional and physical development. Myriad exhibits, including "Water Works, Play-it-Again Theater, Building Bridgetown, Groundworks, Outdoor Adventure, and the Baby's Garden," along with the Museum's art studios, "The Clay Studio, The Wonder Corner and The Garage" encouraged playful inquiry, cultivated creative expression and helped children learn how to learn.
