Robust materials and safe design The kit uses strong ABS plastic with precisely finished smooth edges and stable metal components. This combination provides safe handling during assembly and use in school or home schooling, with a durable build for long-term learning. Cognitive development through hands-on building Modular components promote spatial thinking and problem-solving. The open-ended design supports experimental learning and systematic skill-building during creative projects. Clear energy conversion demonstration Manual input power drives movement that becomes electricity, illustrating basic concepts of conductivity and electromagnetic induction in an approachable way. Versatile and practical use Suitable for educational projects and small lighting experiments. The easy manual operation allows immediate feedback and validation of eco-friendly experiments in different environments. 2-3 practical use scenarios - In-class science project to demonstrate generator concepts and power a small lighting setup. - Homeschool STEM sessions to explore circuits, energy transfer, and hands-on construction. - After-school maker activities to prototype portable energy demonstrations for eco-friendly projects.
