This smart kit connects the worlds of mechanics and electricity through playful experiments. With a motor, gears, and simple circuits, kids learn how electrical energy converts into mechanical motion and how step-up and reduction gear trains work. The assembly is intuitive and encourages exploration.

What kids will learn:

• Gear principles – transmitting force, changing speed, and reversing rotation direction.
• Acceleration and reduction systems – the difference between a large driving gear and a small driven gear.
• Series electrical circuit – how current flows sequentially through all components.
• Motor function – converting electrical energy into mechanical energy.

With 67 components including 6 spinning targets, kids can build their own projects, test ideas, and grow their imagination. A great choice for home learning and a supplement to school experiments.
