Farming - Repeated Percentage Change (Climate Change)

Students begin with a starter matching calculations to a variety of percentage decrease situations.
They go on to an introduction to repeated percentage change and how to use powers in this context. They complete a worksheet using the formulae and interpreting different parts of the formula, finding initial values and the percentage of the decrease. The context for these calculations is farmers experiencing change to their crop yields because of the effects of climate change.
As a plenary, they consider whether a maximum, minimum or median value is most useful in context and finally look at an exam style question asking which investment will offer better long term gains given the changes that climate change is forecasted to bring.

Students can name some different consequences of climate change and
how these affect people and plants.
