Multiple Select

Which of the following statements are true about conductors and insulators?

• A conductor allows thermal energy to move easily through it.

• An insulator prevents thermal energy from moving easily through it.

• A metal pan is an example of an insulator.

• A fabric oven mitt is an example of a conductor.

Open Ended

Describe the difference between a thermal conductor and a thermal insulator, and give an example of each from daily life.

Multiple Choice

What is the role of the metal wire inside a cord in the transfer of electrical energy to a toaster?

• It acts as an insulator and blocks energy.

• It allows electrical energy to move easily to the toaster.

• It stores electrical energy for later use.

• It changes electrical energy to heat before reaching the toaster.
