Great choice, Junior Scientist! Today we're doing the "Conductivity Tester" experiment. Let me explain what we'll discover together. Metals like coins and metal spoons are conductors — electricity flows through them. Plastic and wood are insulators — they block electricity, so the LED stays dark!
Ask an adult to help you connect a battery, wires, and an LED in a simple circuit with a gap to test objects.
