Conductors and Insulators

Front

What is a conductor?

Back

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

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to flow through it easily. Examples include rubber, wood, and Styrofoam.

Front

What happens to heat when it travels through a conductor?

Back

Heat moves quickly through a conductor, making it warm.

Front

What happens to heat when it travels through an insulator?

Back

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

Front

What is the role of insulators in electrical wiring?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) where warmer parts rise and cooler parts sink.
