What is Contrapt Wisconsin?
Contrapt Wisconsin is STEM Forward’s engaging middle school contraption competition. A contraption accomplishes a simple task in the most complicated, fun way possible. Building one can be challenging, but it allows students to develop skills in engineering, simple machines, trial-and-error, project planning, physics, teamwork, and creativity. Our competition enables students to showcase their talents to their peers and our judges, and gives them the chance to earn awards. If you have any questions, please contact Theresa Wolf at twolf@stemforward.org.
