Hand on activity class V A CIRCUIT , CONDUCTOR , INSULATOR

Students of class VA made an electric circuit using wire, Led bulb , battery. They tested a variety of objects by keeping in the circuit to check if the bulb glows in the circuit or not. If the bulb glows the material kept in the circuit to bridge the gap is a conductor. If the bulb does not glows the material kept in the circuit to bridge the gap is an insulator.
Students could explain why the bulb in the circuit is lit .
