Standalone A-level cholera data handling and accompanying powerpoints and worksheets. The main powerpoint introduces cholera and explains how it affects the small intestine’s transport proteins leading to diarrhoea. The second shows the December 2008 Cholera outbreak in Zimbabwe using UN data. The lesson can be introduced with news clips/articles (a search for ‘Zimbabwe 2008 cholera outbreak’ turns up lots). An understanding of the mechanism of cholera infection is not needed to deal with the data handling - which is very much aimed at reliability, sampling and so on. Written to support A-level Biology.
