DIY Wooden Solar Car | 100% Solar Powered Science Kit | Kids STEM Project | Renewable Energy Educational Set | Wooden Solar Vehicle | Develops Intelligence & Creativity | Learn Photovoltaic Principle | Parent-Child Science Toy | Battery-Free Eco Design

• 【Pure Solar Power System】 Operates entirely on solar energy without batteries. Sunlight activates silicon atoms to release electrons, generating current to drive the motor—an immersive renewable energy technology demonstration. • 【Complete STEM Components】 Includes laser-cut wood panels, high-efficiency solar cell, precision motor, gear system, and treaded wheels for hands-on learning of energy conversion and mechanical principles. • 【Live Science Demonstration】 The P-N junction effect converts sunlight to electricity, showing direct "more light → faster speed" correlation for understanding energy efficiency. • 【Family Science Adventure】 Parents can guide experiments testing how sunlight angles affect speed, cultivating scientific thinking and green energy awareness. • 【Eco-Safe Construction】 Made with imported basswood (smooth laser-cut edges) and ultra-low-voltage solar system (under 3V), EN71-certified as a premium STEM educational tool.
