Dr John Snow and cholera

A task to get students to re-enact (sort of!) what Dr John Snow did in terms of identifying the causes of an outbreak of cholera in london.

finding the real cause - story of Snow

finding the real cause graph - a gridded version of the map of London where Snow did his work

finding the real cause graph data - points to plot on the graph showing the water pumps and the cases (fictional) of cholera

students then have to assess their graph and decide what it tells them and then what they shoudl do next
