Insulators and Conductors

What is a conductor?

• Material that does NOT transfer energy.

• Materials that are connected to circuits.

• Materials that transfer energy.

• Materials that

An insulator is a material that:

• Transfers thermal and electrical energy
• Transfers electrical energy and slows thermal energy
• Slows electrical energy and allows thermal energy to pass
• Slows thermal and electrical energy from transfering

A great conductor of energy is:

• wood
• plastic
• metal
• cloth

What object would best complete this circuit?

• A battery
• a peice of yarn
• an insulator
• a 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 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.

The metal copper is there to:

• Provide a conductor for energy to flow from one place to another.
• Provide an insulator for energy to flow from one place to another.
• Provide an insulator to slow the flow of energy.
• Provide a conductor so slow the flow of energy.
