In this activity, students simulate the spread of a virus. They produce a graph representing the spread and analyze the rates of change over time. Students compare how viral and bacterial infections spread in a population.
Students are assigned consecutive integers starting at 1 by their teacher and are asked to stand. Random integers are then used to “infect” students in the class.
As students are infected they are asked to sit down. After each trial the number of infected individuals should be recorded. A scatter plot of the data is created and generalizations are made regarding the spread of disease.
