Insulators and Conductors

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to pass through it easily. Examples include rubber, glass, and plastic.

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to pass through it easily. Examples include metals like copper and aluminum.

Front

Give an example of an insulator.

Back

A jacket is a good example of an insulator because it keeps heat from escaping.

Front

Give an example of a conductor.

Back

A tin can is a good example of a conductor because it allows heat to pass through.

Front

What happens to heat when it passes through a conductor?

Back

Heat moves easily through a conductor, making it warm.

Front

What happens to heat when it passes through an insulator?

Back

Heat does not move easily through an insulator, keeping the material cool.

Front

Is water a conductor or an insulator?

Back

Water is a conductor, especially when it contains impurities like salt.

Front

Is rubber a conductor or an insulator?

Back

Rubber is an insulator because it does not allow electricity to flow through it.

Front

What is the main difference between conductors and insulators?

Back

The main difference is that conductors allow electricity and heat to flow through them, while insulators do not.

Front

Can you name a common insulator found in homes?

Back

Common insulators in homes include materials like fiberglass and foam used in insulation.
