Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good personalities and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate the ability of children to solve problems by themselves. When children encounter problems, they should first see and experience the solution themselves, because parents and teachers solve problems in the process of doing crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green. Playing with DIY crafts can cultivate children's practical ability by using different tools, which fully exercises children's little hands. Brushes, paints, scissors, hot-melt guns, glue"Children are brave to try any tools and to some extent, they are developing different skills. Improving children's self-confidence in the process of handcrafts, we try everything possible together, experience many failures, but we always succeed, which to some extent enhances their self-confidence. Cultivating children's concentration when children explore various tools and handcrafts, they are very focused, and if there is no external disturbance, they can continue to explore.

Experimental Objective: 1. To understand the working principle of a wind turbine.
2. Understanding that the action of force is mutual.

Principle Application: The torque generated by the propeller blades is converted into forward air thrust to propel the car's movement.

Experimental Cognition: 1. The force between two objects is always mutual. When one object exerts force on the other, the other object must simultaneously exert force on this object, and these two forces are mutually called action force and reaction force. The action force and the reaction force are always of equal magnitude, opposite in direction, and act along a straight line.
2. The wind-powered car in this experiment is propelled by the rotation of the fan blades on the body, which generates a force of wind that pushes the air behind the car. This force acts on the air behind the car, and the car exerts a forward reaction force on the air, thereby making the car move forward.

Knowledge Expansion: Inventor Ricardo Kavolaro and his colleagues have built a unique wind-powered car that can actually travel faster than the wind speed in a tailwind. During a recent tailwind test, this unusual wind-powered car reached a speed that was 2.86 times the wind speed, which has caused a sensation on internet forums and universities.
