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 Objective: Through gaming and entertainment, help children learn more scientific knowledge and develop their hands-on skills.

Principle application: A device that converts electrical energy into light. By installing a battery and turning on the power switch, a closed circuit is formed, which lights up the LED beads.

Experimental Cognition: LED table lamps are currently popular types of lamps; LED stands for Light Emitting Diode.

Knowledge Expansion: Generally, based on the light source of the desk lamp, they can be divided into three main categories: LED desk lamps, incandescent desk lamps, and fluorescent desk lamps. Incandescent lamps are the type of desk lamps commonly referred to, which are essentially ordinary light bulbs.

Knowledge Extension: The light bulb first invented by Edison was not a tungsten filament bulb. Attempts using charcoal, hard coal, or metal platinum as filaments failed. A lamp wick inspired him; he used cotton thread to form various arcs, baked them, and extracted a complete piece of carbon wire. After connecting it to power, it emitted light, but it only lasted for a short time before failing. Later, by chance, he used a bamboo fan as a wick, resulting in a wick with a more satisfactory lifespan—it turned out to be Japanese bamboo. Thus, Edison began planting this type of bamboo in large quantities and producing light bulbs in bulk. At the same time, Edison’s power plant started laying electrical wires, marking the beginning of the electric light era. As for the later tungsten filament bulb, it was invented several years later, and Edison was still the inventor.

Safety Warning:
