A material in which electrons are not able to move easily 

• Circuit 
• Insulator 
• Resistance 
• Conductor

What is NOT an example of an insulator in the kitchen?

• An oven mitt
• Pots and pans
• A wooden spoon
• A plastic measuring cup

Mittens help keep your hands warm in winter because:

• They are conductors of heat.
• They are fuzzy.
• They are conductors of electrical energy.
• They are insulators.

The plastic covering on wires is there to:

• Provide a conductor for electrical energy to flow.
• Provide an insulator so that electrical energy will not pass outside of the wires.
• Provide a conductor so that electrical energy can NOT flow.
• Provide an insulator so that electrical energy can flow.
