Water on the Land (AQA A)

Thanks to Dan Mace for these excellent ideas :

For homework I asked the students to write a mix of crossword and cryptic crossword clues for all those key terms in the hydrological cycle. When they came back the next day, they had to write a story of the passage of a raindrop, in pairs, using those terms. Having talked through the 5 key factors (climate, vegetation, soil, bedrock, human activity) they had to swap their stories, and write 'What if' statements throughout - e.g. what if the vegetation was oak trees instead of grass, then… OR what if the rain fell in a city environment instead of a field etc etc.
Finally - 'Making Animals' - if they could redesign South Africa to avoid the problem of overland flow etc, how would they do that - i.e. the ideal river catchment. This provided the context of the lesson - the problems faced by South Africa/Lesotho.
