									                          Conduction of electricity

This experiment is designed to help you find out which materials conduct electricity




Set up the circuit as shown in the diagram.

Test your bulb by touching the two crocodile clips together to check that the bulb
lights strongly. If it doesn’t your batteries are flat or the bulb is broken.

Copy and complete the table. Write in whether the bulb is on or off and if it is on
whether it is bright or dim.
Try and test the materials mentioned but also find some more for yourself. There are
some spaces left for you to fill in these others.

              Material            Bulb on/off          Bulb dim/bright
           Copper
           Iron
           Brass
           Plastic
           Rubber




Try and explain with the help of your teacher why some materials conduct electricity
and other do not.

You might find the file called Electricity on the Foundation section of the web site
