Conductors & Insulators
Electrical Conductors Objects that allow electrical charge to flow easily
Conductors & Insulators Static Electricity: an imbalance of electric charge at rest on the surface of an object
Electrical Conductor Example: The coil from a electric heater gets hot and conducts electricity well
Good Conductors • Metal is a good conductor of electricity
Property of Electrical Conductor: In all good conductors electric current flows through them without resistance Example: Electricity flows through the coil in the power line coils without resistance and easily
Insulators Objects that do not conduct electricity well
Good insulators: Insulation, plastic, certain materials.

Who’s Hungry? ? ?
To eat you must…. • Decide which material I need to cook with. Do I need to cook with an Insulator or a Conductor? • Insulator- does not allow heat to travel through it easily. • Conductor- does allow heat to travel through it easily.
And the Answer Is…
Conductor!!!
On page in your journal make a T-chart. Label one side conductors and the other side insulators. As I show you the next slides, look at the picture and decide if it is a conductor or insulator. Write it in the appropriate column in your journal.
