Scientific exploration and hands-on practice: DIY hand-crank generator kit. Through step-by-step assembly, a power generation system is constructed, guiding children to understand the basic mechanical structure and the principle of electrical energy conversion during the operation Creativity and logical thinking development: It covers system steps such as motor fixation, gear transmission, and circuit connection. In the hands-on practice, logical planning, spatial imagination, and problem-solving abilities are exercised Safe and durable solid wood material: Solid wood components with stable wood properties, wear-resistant, and scratch-resistant are selected. The structure is stable and the operation is smooth. The edges are processed safely to ensure a smooth and worry-free production process Multifunctional and fun experience: After the generator is assembled, it can light up a bulb and can be expanded to have practical functions such as charging mobile phones, etc., enhancing the sense of achievement in the experiment and the interest in scientific exploration Parent-child collaboration and engineering enlightenment: Clear step-by-step guidance supports parents to collaborate. In the process of completing together, children's patience, concentration, and early engineering thinking are cultivated
