Spread of disease

Modelling the spread of disease and the success rate of immunisation is vital for disease control. This task looks at different ways of modelling the spread of disease, using: 1) a dice; 2) a pack of cards; and 3) a spreadsheet.

Suggested approaches

The activity is suitable for group or paired work with plenty of opportunity for collaboration and discussion with the whole class on how the model works and what happens if you change a variable, e.g. the infection rate. It also enables students to see clearly the spread of disease using several different modelling approaches. The best way to work through the different models is: counter plague (counters and dice per group); 26-card epidemic (one pack of cards per group); spreadsheet model. Discuss findings at the end.
