Key Stage 2

Meaning

Thermal Conductivity is how quickly a material can be heated or cooled.

About Electrical Conductivity

If a material can change temperature quickly it is a thermal conductor.
If a material changes temperature slowly it is a thermal insulator.

Examples

Thermal Conductors
Metals
All metals make good thermal conductors.
Thermal Insulators
Plastic Rubber Air Brick

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.

Key Stage 3

Meaning

Thermal Conductivity is how quickly thermal energy can be transferred through an object.

About Electrical Conductivity

If a material can change temperature quickly when heated it is a thermal conductor.
If a material changes temperature slowly when heated it is a thermal insulator.
