Galaxy STEM Fest

Get ready to blast off into the future at Galaxy STEM Fest!

This festival promises a fusion of history, sci-fi, and STEM, with presentations, hands-on activities, kids cosplay contest, music, food trucks, and much more. Join us as we explore the intersections of imagination and innovation, all while supporting a noble cause – raising funds to send local girls to CAMP INNOVATION this summer at the Arizona Science Center! Galaxy STEM Fest aims to ignite curiosity and inspire the next generation of science explorers. This event is funded in part by a generous grant from Arizona Humanities.
