HEAT: Chapter 1 - Lessons 1-3

Why are metals useful for making electrical wire?

• Metals do not bend.
• Metals hold much heat.
• Metals are insulators.
• Metals are conductors.

Which is NOT an insulator.

• Wool
• Plastic
• Copper
• Glass

Something electricity can't move through easily is called a(n) ______.

• conductor

• wire

• shoe

• insulator

What is a example of a conductor?

• wood 
• metal
• rubber
• rock

What is a example of an insulator?

• metal 
• rubber
• water

Water is an insulator.

• True
• False

Rubber is an insulator.

• true
• false

What are conductors?

• A conductor is a material that allows electric charge to move through it as an electric current. Usually the charge is carried by electrons, and the conductor is a metal.
• an insulator
• an conductor 
• A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators. Compare conductor.
