Looking at the diagram above, do you think the bulb in this circuit will light? Discuss it first, and then set up the circuit. Have a teacher or another adult strip the insulation from the wires. Put plenty of salt in the water.
Write your observations here:
In this experiment, we added salt to the water to make the bulb light. When a source of electricity has higher voltage than your D-cell batteries, the electricity will travel through water with or without salt in it. So, if lightning struck a lake, or a blow dryer fell in the sink, electricity would travel through the water. Anyone touching that water could be electrocuted. (Electrocution means fatal contact with electricity.)
