Summertime Discovery

Summertime Discovery is a camp-like experience for children ages 4 to 11 (or entering grade 6). Our experienced program coordinators and energetic student assistants turn summer into a time of creativity, exploration, and play.

Our 2023 program operates for ten weeks and takes place on the Principia School campus. Activities include outdoor play, arts, crafts, science, sports, and swimming—all set to an imaginative weekly theme that creates experiences children will remember for summers to come! See this year’s themes and schedules below.
