Interactive Labs

Disease Lab

Lessons > The Virgin Field > Step 2

Unlike some of the other interactive labs, this model has some randomness built in to reflect the real spread of a disease, which is a matter of probabilities. Despite this variability, you can get a sense for what effect each factor has on disease spread.

Before running the simulator, predict whether the sick days per capita will be higher or lower with low population density. Record your prediction in the data table and then run the simulator to 100 days three times, recording the data each time. Make a prediction for high population density, record it in the data table, and run the simulator three times, recording that data in the table. Answer the following:

  1. What could be done to prevent the spread of disease in a low population density? What kinds of challenges would high population density present?
