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 with 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: Improve children's hands-on skills through game-based entertainment.

Principle Application:
Solar panels primarily use semiconductor materials. They convert light energy into electrical current through photoelectric conversion. When sunlight hits the semiconductor material, a portion of it...
Light is reflected by the surface, while the rest is absorbed by or transmitted through the semiconductor. Of course, some of the absorbed light becomes heat, and other light interacts with the valence electrons of the semiconductor atoms, resulting in...
Electrons; in this way, light energy is converted into electrical energy in the form of electrons.

Experimental Cognition: The solar car must operate under sunlight to generate power.

Knowledge Expansion: Solar panels are the core component of a solar power generation system, and also the most valuable part of it. Their function is to convert the solar radiation into electrical energy—either for storage in batteries or to power loads. The quality and cost of solar panels directly determine the quality and cost of the entire system.

Knowledge Extension: Solar panels only generate power under sunlight. If there is no sunlight (overcast weather) or at night, you can use a 5 or 7 volt battery to replace the solar panels for power (the battery must be connected manually, as there is no dedicated slot on the product), and it will still achieve the desired effect!

Safety Warning: All components in this product are specialized equipment used for student experiments. Please use it under the supervision and guidance of teachers and parents to ensure safety! All products are prohibited from being eaten! Not suitable for children under three years of age; avoid proximity to fire sources. Before assembly, check that the circuit is unobstructed and all components on the circuit are intact, and that all contacts are good. On the battery, + indicates the positive pole and - indicates the negative pole. During assembly, be careful not to get glue on your eyes or skin.
