Adaptive teaching
Pupils needing extra support
Could be provided with additional data points from the answer table for the predicting evaporation rates activity; could use the Activity: Inventing an Atmospheric water generator (support) to help them draw their design.
Pupils working at greater depth
Could explain how sweating helps cool us down. (The liquid produced from sweating uses body heat to evaporate from our skin and turn into a gas, which reduces our body heat and makes us feel cooler.)

Knowledge outcomes
- I can describe the conditions needed for evaporating (heating above the boiling point of the material) and condensing (cooling below the condensing point of the material).
- I can describe the property changes as a material evaporates from having a fixed volume to not having a fixed volume.
- I can describe the property changes as a material condenses from not having a fixed volume to having a fixed volume.
- I can name the start and end states when materials evaporate (liquid to gas).
- I can name the start and end states when materials condense (gas to liquid).
