Wind Power Electric Car Kit for Kids Wood Educational Science Physics Experiments Circuit Kindergarten Stem Toys Students

Product description

Material:  Plastic+Wood
Size:         12 X 8 X 12.5cm
Recommended age: 5 year and older

Purpose:

1. Use the weight drop to drive the wheel rotation principle to build a car.
   
2. Let students simply understand the conservation of energy.
3. The ability to cultivate their interest in learning, as well as to the understanding of scientific knowledge

Experimental Report:

When the weight falls and the wheel rotates, what is the top of the shelf? It is called a pulley, so what is the role? It is possible to change the direction of the force. The weight is moved downward by gravity to produce downward kinetic energy. The rope and the fixed pulley are used to change the direction of the force and the other end becomes the upward movement. The rope pulls the rope wound on the shaft to make the wheel turn to achieve the purpose of driving.
