Note to Teachers
In science, heat is not generally considered a noun. It is a verb. Heat is something you do to an object. It is best practice to avoid making statements like 'heat passes through a material quickly' because heat is not a physical entity, but an action or process. A thermal conductor allows thermal energy to pass through it easily. A thermal conductor can be heated quickly.
