Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows heat and electricity to pass through it easily.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through it easily.

Front

Give an example of a good conductor of electricity.

Back

Copper wire is a good conductor of electricity.

Front

Give an example of a good insulator.

Back

Wool is a good insulator that helps keep heat.

Front

What happens to heat when it passes through a conductor?

Back

Heat moves easily through a conductor.

Front

What happens to heat when it passes through an insulator?

Back

Heat does not move easily through an insulator.

Front

Why do we use insulators in electrical wires?

Back

Insulators protect us from electric shocks by preventing electricity from escaping the wires.

Front

What is the role of wool earmuffs in cold weather?

Back

Wool earmuffs act as insulators to keep heat from escaping and keep ears warm.

Front

Which material is NOT a good conductor?

Back

Plastic is not a good conductor; it is an insulator.

Front

What is the main difference between conductors and insulators?

Back

Conductors allow heat and electricity to flow, while insulators resist the flow.
