Describing stores

Wrong Track: The ball on the roof has energy.

Right Lines: The ball on the roof is a gravitational energy store because of its position in the Earth's field. Moving the ball towards or away from the Earth alters the contents of the gravitational store.

Energy stores can depend on more than one physical …

Thinking about the learning

Pupils need to develop the idea that energy stores often depend on more than one physical object.

Thinking about the teaching

You need to treat this lightly, but firmly, taking care with your own descriptions so that you emphasise the whole, rather than just a physical object. In the case of fuels, the energy store is the fuel-plus-oxygen, not just the fuel or just the oxygen.
