1. Arrange 7 paper cups for these 7 liquids: milk, curd, lemon juice, salt water, sugar water, tomato juice, plain water. Use a regular battery, and three small copper wires. Connect one end of one wire to the battery and other end into a cup, one end of the second wire to the battery and other end to the LED bulb; and third wire from the LED bulb to a cup. Check which liquid is a conductor of electricty, which liquid is an insulator. Record your observations.
