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.

The purpose of the experiment: This product focuses on the cultivation and exercise of children's ability to practice and think, ultimately forming a good habit of independent thinking, and falling in love with scientific exploration. A simple understanding of circuits.

Principle Application: The chemical energy in the battery is converted into kinetic energy of the motor, which then drives the active gear to rotate. When the active gear touches the ground, the car moves forward with the rotation of the active gear. When the passive gear touches the ground and meshes with the active gear, the passive gear will rotate along with it, but in the opposite direction, thereby achieving the reverse movement of the car. This is why it is called the gear return car.

Experimental Cognition: The Principle of Gear Transmission: That is, a pair of gears with the same module (tooth shape) meshing with each other will transfer power from one shaft to another to complete the power transmission.

Knowledge Expansion: Gear Transmission refers to a device that uses a gear pair to transfer motion and power. It is one of the most widely used mechanical transmission methods in modern equipment.

Knowledge Extension: Gear transmission relies on the meshing of teeth to perform work, and the tooth is the part of the gear that directly participates in the work, so the failure of the gear mainly occurs on the tooth. The main failure forms include tooth breakage, tooth surface pitting, tooth surface wear, tooth surface bonding, and plastic deformation, etc.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision of teachers and parents to ensure safety! Do not consume any of the products! They are not suitable for children under three years of age. Do not approach fire sources. Before assembling any batteries, please check if the circuit is clear, all parts of the circuit are complete, and all contacts are good. The + on the battery is the positive pole, and - is the negative pole. Be careful during the assembly process, and if glue is used, do not get it in your eyes or on your skin.
