Recycling cities: a unit for 13-16 year olds

Produced by The Centre for Industry Education Collaboration (CIEC), these materials help students to gain an understanding of a number of scientific ideas through investigating how a refrigerator works. The key ideas covered include:
* liquids require heat to evaporate
* some gases can be liquefied at room temperature by compression
* vapours release heat when they condense.

The activities described in these materials enable students to:
* consider how a refrigerator works
* watch a demonstration of cooling caused by evaporation and relate it to an industrial deep freezing process
* investigate a working refrigerator and construct a temperature profile.

Full teacher guidance and student activity sheets are included in the materials.
