This free online learning destination is full of fun, interactive STEM- and literacy-building topics boosted by Maker experiments! Keeping kids and their families learning together throughout the summer and out-of-school time, Camp Wonderopolis can help build vocabulary, background knowledge, reading comprehension, critical thinking, and other literacy skills along the way.

When you register as a Camper (kids of all ages) or Counselor (parents and guardians, community and library program staff, teachers), you'll enjoy learning through wonder—an approach created and honed by the award-winning! This year's Camp lets Campers build their own version of Wonderocity as they explore their way through 42 lessons about engineering, construction, and city planning.
