Factor #4: Initial Sick

Use the "initial-sick" slider in this model. Conduct your investigation by looking at how the disease spreads based on how many are sick at the beginning. Change initial sick to: 1, 5, 10, 20, 40, 60, 80.

Look at the graph on the side, in Question 1 record your observations of the graph for each level.

Questions

Please answer the questions below.

Add your observations from the graph for each trial with different number of "initial-sick."

 

At which number of initial sick does the population of organisms stay the healthiest?

1
5
10
20
40
60
80

Is there a level where you see a significant increase in the number of sick or how quickly they become sick? What level is that?

1
5
10
20
40
60
80

Give an example of what "initial sick" is like in real life. How does having a smaller or larger number of organisms who are infected with the disease matter?
