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: To enable children to learn more about scientific knowledge and their own ability to practice by means of game entertainment.

Principle Application: A device that converts electrical energy into light. When a battery is installed and the power switch is turned on, a closed circuit is formed, thus illuminating the LED light beads.

Experimental Cognition: LED desk lamps are very popular among many desk lamps now, and LED stands for Light-Emitting Diode.

Knowledge Expansion: In general, based on the light source of the lamp, we can classify desk lamps into three major categories: LED desk lamps, incandescent desk lamps, and fluorescent desk lamps. Incandescent lamps are the types of desk lamps we are usually referring to; they are the standard light bulbs.

Knowledge extension: Edison's earliest invention of the light bulb was not a tungsten filament bulb. It failed when using charcoal, hard charcoal, and metal platinum as filaments. A kerosene lamp wick reminded him, and he used cotton thread to form various arcs, baked them, removed a section of carbon thread, and when installed and connected to the power source, it really emitted light, but it only lasted for a while before it broke. Later, by chance, he also used a bamboo fan as a filament, and the result was a more desirable filament life. It turned out that this was a type of Japanese bamboo. Therefore, Edison began to mass-cultivate this bamboo and started mass-producing light bulbs. At the same time, Edison's power plant began to lay electrical wires, marking the beginning of the age of electricity. It was several years later before the tungsten filament bulb was invented, and the inventor was still Edison.
