Preface:

In today’s era where more and more emphasis is placed on children’s education, scientific enlightenment education has gradually become an important topic in the field of education. More and more teachers and parents are focusing on developing children’s scientific literacy from an early age, enabling them to establish good character and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child time together, enhance parent-child relationships. The moments we spend with our children are free from phones, iPads, or televisions—only joy, interaction, and communication. It helps children develop the ability to solve problems on their own. When faced with challenges, children must first see, experience, and resolve them themselves, just as parents and teachers do during craft activities. It also stimulates children’s imagination—in their world, cars can fly in the sky, and the sun can be green... Playing DIY crafts allows children to develop hands-on skills by using various tools, giving their hands ample opportunity to move. Pencils, paints, scissors, hot melt glue, tape—they all challenge children to try, and to some extent, help develop different skills. It boosts children’s confidence. During craft activities, we explore countless possibilities and experience many failures, but we always succeed, which in turn enhances their confidence. It helps cultivate children’s focus. As they explore various tools and crafts, they remain very focused; without external distractions, they can continue exploring indefinitely.

Experiment Purpose: 1. To understand the working principle of the wind turbine.
2. It is understood that the effect of force is mutual.

Principle application: The torque generated by the propeller blades is converted into forward air thrust, which drives the vehicle to move.

Experimental Cognition: 1. The force exerted between two objects is always mutual. When one object exerts a force on another, the other object must also exert a force on the first object at the same time. These two forces are referred to as action force and reaction force. Action force and reaction force are always equal in magnitude and opposite in direction, acting along a straight line.
2. The wind car used in this experiment generates backward thrust through the rotation of the fan blades on its body. The wind exerts a force on the air behind the vehicle, and the air behind the vehicle provides a forward reaction force on the car, thereby causing it to move forward.

Knowledge Expansion: Inghil-Kavalaro and his colleagues invented a unique wind-powered vehicle that can travel faster than the wind itself when moving with the wind. This extraordinary wind vehicle achieved 2.8.6 times the wind speed during a recent test, and its unusual design caused a stir on internet forums and universities.
