What kind of contraption will you build? “Crazy Contraptions” is a thought provoking activity that engages students in the design and construction of exciting and innovative Rube Goldberg style mechanisms. The comprehensive Crazy Contraptions Activity Guide facilitates the conceptualization, understanding and application of simple and complex machines. Utilize the template for a standard frame on chipboard or another surface, or set your contraption on a 12"x12" wood base with drilled slots, perfect for connector strips. You can purchase the Crazy Contraptions Base from TeacherGeek or make the base using this template.
