Full Specification Text[]
a) The transfer of energy by conduction, convection, evaporation and condensation involves particles, and how this transfer takes place.
b) The factors that affect the rate of evaporation and condensation
Starter Activities[]
- video of paint drying
- [video evaporation]- language a bit challenging but very well visualised.
- Put a small amount of nail varnish remover on to the back of students hands as they enter the room. They will feel it getting colder.
Activities to introduce new ideas[]
- Use the online kinetic model, turn up the gravity and turn down the heat until you get a liquid. Observe the evaporation and the graph showing the distribution of energy.http://www.falstad.com/gas/

Practical activities[]
Demonstrations[]
- Use "freeze spray" or "pipe freeze" to demostrate cooling by evaporation
Class practicals[]
- Put some nail varnish remover (proponone) or ethanol on students skin to allow them to feel the cooling effect of evaporation
