Creative DIY Small Table Lamp Technology Small Production Primary School Students Manual Materials Science Experiment

1. Material: wood
2. Size: 9.5 x 6 x 16cm
3. Features: "paper cup small table lamp", beautiful appearance, simple production, easy to succeed, suitable for children of lower grades. The use of environmentally friendly materials, that is, the water cups that we have abandoned in our daily life have become waste, and after simple production, we have changed into a variety of beautiful decorative nightlights to achieve waste recycling and achieve energy conservation and environmental protection.
4. Working principle: This is a typical switching circuit. The battery provides power. The current is controlled by the switch. When the current is turned on, the current flows through the switch. Finally, after the LED lamp, the current is converted into light energy, so that the small table lamp emits light.
5. Power: 2 x AA batteries (not included)
