Observe the meter to see if and how much current is flowing through the item being tested. Your screen will look something like this: Record the item and the amount of current (if any) on the data sheet. Questions & Observations Which items were conductors and which were insulators? How did you know? Were you surprised by any of your results? Which ones and why? Before you tested the objects, how did you decide if you thought an object would be a conductor or an insulator? Compare the objects that you have discovered are conductors. What do they have in common? Is water a conductor or an insulator? Why would it be dangerous to be wet or standing in water when working with electricity? Extension Activity Try testing the conductivity of different water samples. Be sure to include distilled water (pure) as well as tap water, local pond water and sea water. Insulators/Conductors Predicted Insulators Predicted Conductors
