When the switch goes out of the circle, the light will go out. Each students will be given materials needed to make a flashlight. Make sure wire is connected to the battery and the bulb. Then use the aluminum foil as a conductor. If all connections are correct, current is complete and the bulb will light up.
Students can decorate flashlight any way they choose.
One wire from the battery terminal and the other wire to the bulb assembly are to be connected to become the test probes. Push them firmly into the erasers of the two pencils. When you apply testing probes to each object, the bulb will light up to show you that all metal objects are conductors of electricity. The bulb will not light up if objects are not good conductors. Students will make a chart to list and show good, poor and non conducting objects.
