Challenge Island® is a one-of-a-kind enrichment program on the cutting edge of S.T.E.A.M. (science, technology, engineering, art, & math) education and 21st Century Learning. We take kids on unique “island” adventures where they work in collaborative tribes to tackle various STEM/STEAM challenges using only the materials in their treasure chest and their boundless imaginations.


Students will participate on different themes like Wizardry Camp, Slime Squad, Cool Careers and more. Camp will be offered M-F in one hour sessions working with their tribemates by grade level.
