Student Directions and Resources
You will be using a similar version of the model from the disease transmission lesson. In this lesson we are going to look at the factors involved in the spread of disease.
1. Factor #1: Infectiousness
Use the infectiousness slider in this model. Conduct your investigation by looking at infectiousness rates of: 0%, 10%, 25%, 40%, 60% 80%, 100%.
Look at the graph on the side, in Question 1 record your observations of the graph for each level.
Question 1.1
Question 1.2
At which infectiousness level do the organisms stay the healthiest?
0%
10%
25%
40%
60%
80%
100%

Question 1.3
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?
0%
10%
25%
40%
60%

Question 1.4
Give an example of what the level of infectiousness looks like in real life. Are there diseases you know of that are more infectious or less infectious?
2. Factor #2: Recovery Rate
Use the "chance-recover" slider in this model. Conduct your investigation by looking at recovery rates of: 1%, 10%, 20%, 30%, 50%, 70%, 100%.
Look at the graph on the side, in Question 1 record your observations of the graph for each level.
Question 2.1
Add your observations from the graph for each recovery level here.
Question 2.2
At which recovery level do the population of organisms stay the healthiest?
Question 2.3
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?
Question 2.4
Give an example of what the level of recovery looks like in real life. Are there infectious diseases you know of that are easier or more difficult to recover from? Are there any that organisms can't recover from and continue to live with?
3. Factor #3: Duration
Use the "duration" slider in this model. Conduct your investigation by looking at duration of the disease for 7, 10, 15, 20, 30, and 45 days.
Look at the graph on the side, in Question 1 record your observations of the graph for each level.
Question 3.1
Add your observations from the graph for each duration level here.
Question 3.2
At which duration of the disease do the population of organisms stay the healthiest?

Question 3.4
Give an example of what duration time is like in real life. Are there infectious diseases you know of where how long you are sick or contagious is shorter or longer?
4. 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.
Question 4.1
Add your observations from the graph for each trial with different number of "initial-sick."
Question 4.2
At which number of initial sick does the population of organisms stay the healthiest?
1

Question 4.4
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?
