Does it carry electricity? Category: Science
Dated: 2011-11-05
 
Use these four tests to help you decide whether something is made from metal.

 

Steps to be taken

1.  Test your material with a battery, a bulb and two wires.
2.  All metal conducts, or carries, electricity.
3.  For the test to work, you must touch the wires on bare polished metal, not on paint.
