Preface

Today, with an increasing emphasis on children's education, enlightenment education has gradually become an important topic pursued and explored in the field of education. More and more teachers and parents are beginning to pay attention to cultivating children's qualities from an early age, enabling children to develop good personalities and behavioral habits from the very beginning. Parent-child interactive handicrafts can enhance the quality of parent-child companionship and improve the parent-child relationship. The time we spend with our children, there are no mobile phones, ipads or TVS, only joy, interaction and communication. It can cultivate children's ability to solve problems by themselves. When encountering problems, children should first observe and experience them to solve them, because this is how parents and teachers solve problems during the process of doing handicrafts. 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 handicrafts can cultivate children's hands-on ability. By using different tools, children's little hands get sufficient exercise. Brushes, paints, scissors, hot melt gun, glue..... They are willing to try any tool and, to a certain extent, develop different skills. During the process of handicrafts, we tried every possible way together, experienced many failures, but always succeeded, which to a certain extent enhanced the child's self-confidence. Cultivating children's concentration: When children are exploring various tools and handicrafts, they are very focused. If there is no external disturbance, they can keep exploring.

Experimental objective: Toys assembled by children themselves can stimulate their innate desire for exploration and growth, establish a learning environment, create a space for activities and exploration, and help children maximize their potential. The right choice can create good opportunities for children to learn, and its influence will last a child's entire life. Parents playing with their children and providing appropriate guidance can help children complete the process of acquiring knowledge, building relationships, recognizing rules, becoming independent and developing self-awareness during the process of having fun.

Principle application: This toy car utilizes the mechanical kinetic energy converted from electrical energy
The working battery provides electrical energy to the motor. After the motor starts to rotate,
The main shaft gear on the motor drives the intermeshing large gears to rotate
The large gear is coaxial with the wheel, so that the car can be driven
I've exercised.

Experimental cognition: Electrical energy can be converted into mechanical energy to drive a racing car.

Knowledge Expansion: An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M in a circuit. Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. A generator is represented by the letter G in a circuit. Its main function is to convert electrical energy into mechanical energy.

Knowledge extension To effectively reduce and overcome the influence of air resistance when a car is traveling at high speed, people have designed and used the rear wing of the car. Its function is to make the air exert a fourth force on the car, that is, to generate a large adhesion force to the ground. It can offset part of the lift force, effectively control the car's ascent, and accordingly reduce the wind resistance coefficient, allowing the car to travel closely on the road ground. Thus, the stability of driving performance.
