Conductors of Heat and Electricity

How do conductors differ from insulators?

• Conductors make electricity and heat pass through while insulators don’t.

• Conductors and insulators make electricity and heat pass through.

• Conductors and insulators do not make electricity and heat pass through.

• Insulators make electricity and heat pass through while conductors don’t.

Mr. Stevens set up the demonstration lab for his classes. When both wires touched the coin, the light bulb lit up. What did this tell the students about the coin?

• It is a good insulator.

• It is a good conductor.

• It has low melting point.

• It would be attracted to a magnet.

Our body is also a good conductor of electricity because of the presence of _________________.

• blood

• hair

• water

• skin

You know that the object connected to the wires is a conductor because: (a)  

• The light bulb is glowing bright.

• It's a complete circuit.

• It's a closed circuit.

• The object is shiny.

The object that would best complete this circuit is a (a)   .

• battery

• a piece of yarn

• an insulator

• a conductor

Why are cooking pots made of metals such as iron and aluminum?

• Heat moves quickly through metals.

• Metals are cheap.

• Metals are easy to find.

• Metals don’t melt.

Tony is boiling a pot of water on the stove. The black handle is made of rubber, and the pot is made of copper. Why is the black handle made of rubber and the pot of copper?

• Rubber is good conductor, and copper is a good insulator.

• Rubber is a poor insulator, and copper is a poor conductor.

• Rubber is a good insulator, and copper is a good conductor.

• Rubber is a good conductor, and copper is a good insulator.
