The Maker Expo offers four exciting challenges for students in grades K–12 to showcase their creativity and ingenuity. All entries will be displayed at the Expo, with some participants invited to give presentations. Each challenge will be judged on how well students meet the requirements, capture the judges’ attention, and connect to this year’s theme: Worlds Collide, Ideas Ignite.
