The Brackitz Structure, Wheels & Pulles Set combines the Structures Classroom Set, the Brackitz Wheels & Axles and Pulleys & Cranks Modules empowers students to add the wonder of motion to their structures. Once they've created their simple moving machines, students can explore authentic STEM concepts as they measure distance and speed or experiment with the impacts of variable incline or decline degrees. It’s a great way to integrate the skills and concepts of math, science, engineering and design thinking. FREE downloadable lesson plans included.
