Here’s a fully comprehensive simple machines set for middle school. Contains 1,460 pieces and color-coded building instructions to build 30 different models.

Students can build 4 of each model type at the same time.



Models demonstrate:

• 1st, 2nd and 3rd class levers
• Fixed, movable, compound, and block and tackle pulley systems
• Wheel and axles with the force applied to both the wheel and the axle
• Inclined planes, screws and wedges
• Spur, crown, sprocket, rack and pinion, transmission and differential gear systems.

The set includes a teacher’s guide that contains key facts and inquiry-based lesson plans on each model, plus design briefs for students to create their own working models based on concepts being studied.
