Engino’s Discovering STEM Simple Machines set combines five basic “Discovering STEM” sets into one master kit, letting kids build up to 60 working models with 140 pieces. It covers the full range of mechanisms that give machines their edge, including levers, the wedge, the wheel and axle, the screw, and the inclined plane, all built with a snap-fit brick system. Recommended for kids 9+, it’s built for young engineers ready to see how mechanical advantage actually works.

• 140 pieces snap together to build up to 60 different working models
• Covers simple machines mechanisms: levers, the wedge, the wheel and axle, the screw, and the inclined plane
• Combines all five basic sets from the “Discovering STEM” series into a single comprehensive kit
• Shows how these mechanisms multiply or reduce force, increase or decrease speed, and convert one type of motion to another
• Recommended for kids ages 9+ exploring hands-on mechanics and experimentation
