Boston Children's Museum opened in 1913 and became one of the first American museums to pull its objects out of glass cases and put them directly into children's hands, a shift the film credits with reshaping how museums across the country think about kids and learning. The camera follows children through the galleries as they touch, climb, and rearrange the exhibits rather than just look at them. In the Grandparent's Attic display, kids dig through a trunk of old clothes and try on the roles adults play, dressing up as shopkeepers or office workers. Elsewhere the New Balance Foundation Climb has them physically working out balance and movement rather than reading about it. Museum staff appear throughout, describing the thinking behind exhibits built around play instead of instruction. The film stays close to the floor of the museum itself, watching what happens when children are given permission to handle everything in the room.
