Lesson covering phenomena of liquids and vapours. Condensation and evaporation in real life examples e.g. sweating and refrigeration, linking to kinetic theory. Developing: Distinguish between boiling and evaporation. Securing: Relate evaporation to the constant cooling of the liquid from which the particles have escaped. Exceeding: Explain the cooling of a body in contact with an evaporating liquid.

Presentation to help students get to grips with prefixes and scientific notation - contains practice questions - also suitable for higher KS3 classes. Developing: Recall the 8 basic prefixes. Secure: Most students will be able to use the 8 basic prefixes in the keywords and explain what they mean with an example.
