* explain the mathematics behind exponential growth
* compare how well the latest data (for Covid-19 deaths in the UK) fits an exponential growth curve
* describe what can be done to "flatten the curve" - and what that means mathematically.

There's also a follow up here from 31/03/20 with, by request (!) some more about logarithms, then going on to say more about using log graphs to test for exponential growth and then using that to show that growth rates are hopefully now starting to fall in Italy and Spain.
