Surviving the winter free course icon Level

Nature & Environment 

Surviving the winter

In this free course, Surviving the winter, we study one aspect of the fluctuating nature of an organisms environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the demands of a fluctuating environment in quite different ways. As cyclic variations are a widespread feature of environments, the range of adaptations to them is an important source of biological diversity.

Modelling pollution in the Great Lakes free course icon Level

Nature & Environment 

Modelling pollution in the Great Lakes

This free course, Modelling pollution in the Great Lakes, introduces the idea of modelling with mathematics. The course centres on a mathematical model of how pollution levels in the Great Lakes of North America vary over a period of time. It demonstrates that, by keeping the model as simple as possible, extremely complex systems can be understood and predicted.
