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.

To enhance your Camp experience, we have created Family Camp Kits available for purchase at the Wonder Store. These kits help bring Camp to life with information and materials to build hands-on learning experiences through the summer and beyond. Family Kits include a printed Family Guide, Maker activity supplies, a Wonder Journal, a deck of Wonder Cards, and other goodies to help families share the fun of Wondering and learning together. Program Kits are also available, providing online training, support materials, and ways to announce your location as an official Campsite. Check out full details and order your Camp Kit at the Wonder Store.
