Preface

Today, with an increasing emphasis on children's education, scientific 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 scientific literacy from an early age, enabling children to develop good personality 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 his 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: To enhance children's hands-on ability through game entertainment.

Principle application Solar panels are mainly made of semiconductor materials. They generate current by absorbing light energy through photoelectric materials and undergoing photoelectric conversion. When sunlight shines on the semiconductor, part of the light is reflected off the surface, while the rest is absorbed or transmitted by the semiconductor. Of course, some of the absorbed light also turns into heat. Some other light collides with the valence electrons of the atoms that make up the semiconductor, thus converting light energy into electrical energy in the form of generating electrons.

Experimental cognition: Solar-powered races and lunar rovers can only generate power under sunlight.

Knowledge Expansion: Solar panels are the core component of a solar power generation system and also the most valuable part of it. Its function is to convert the radiation capacity of the sun into electrical energy, either to be sent to the battery for storage or to drive the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system.

Knowledge extension: Solar panels can only generate power when exposed to sunlight. If there is no sunlight (on a cloudy day) or at night, you can use a AA or AA battery to replace the power supply of the solar panel (bring your own battery for connection, as there is no dedicated battery slot on the product), and it can still achieve the corresponding effect!
