Insulators and Conductors

What are conductors?

• Materials that allow energy to flow through them easily

• Materials that do not allow energy to pass through them easily

• Materials that are used to cover wires

• Materials that are used to make handles for pots

Which of the following is a common conductor?

• Copper

• Rubber

• Plastic

• Wood

Why are insulators used to cover electrical wires?

• To keep electricity from escaping

• To allow electricity to flow easily

• To transfer thermal energy

• To make wires look attractive

What is the role of conductors in thermal energy transfer?

• They allow heat to move through them easily

• They stop heat from reaching our hands

• They slow down the transfer of heat

• They are used to make oven mitts

Why do we wear oven mitts when holding a hot pan?

Use new vocabulary words conductors and insulators.

How do insulators help in cooking?

• They keep the heat from reaching our hands

• They allow pots to heat up quickly

• They transfer heat efficiently

• They are used to make cooking pots

Why does electrical wiring need to be a conductor and not an insulator?
