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 different 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: The working principle of the hand-crank generator is to manually cut magnetic field lines to generate electricity.

Experimental Cognition: The power generation process of the alternator is that a closed coil rotates in a magnetic field, utilizing electromagnetic induction to produce induced current. Therefore, its power generation principle is electromagnetic induction.

Knowledge Expansion: During the power generation process, a hand-cranked generator converts mechanical energy into electrical energy. The coil generates an induced electromotive force within the rotating magnetic field. The basic components of a typical hand-cranked generator include the stator and rotor. The stator usually contains permanent magnets, while the rotor is made of coils. Driven by external forces, the coils move along the magnetic field lines, generating an induced electromotive force. If the internal coils form a closed circuit with the external circuit via brushes, an electric current will be generated in that circuit!

Knowledge Extension: A generator consists of components such as the stator, rotor, end cover, base, and bearings. The stator is made up of the base, stator core, winding pack, and other structural elements that hold these parts together. The rotor can rotate within the stator and perform motion that cuts through magnetic field lines, thereby generating an induced electric potential to produce electricity.

Safety Warning:

All components within this product are specialized equipment 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. They are not suitable for children under three years of age. Do not bring them close to sources of fire. If using batteries, check that the circuit is unobstructed and all components on the circuit are intact, and that all contacts are properly made. On the battery, + indicates the positive electrode and - indicates the negative electrode. During assembly, be careful not to get glue on your eyes or skin.
