==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.

===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 Store|thermal energy]] can be [[Energy Transfer|transferred]] through an [[object]].

===About Electrical Conductivity===
: If a [[material]] can change [[temperature]] quickly when [[heat]]ed it is a [[Thermal Conductor|thermal conductor]].
: If a [[material]] changes [[temperature]] slowly when [[heat]]ed it is a [[Thermal Insulator|thermal insulator]].
