DISEASE LAB Name:_______________________Per:
____
Problem:
How does change in population density affect
the spread of influenza in a population?
Hypothesis:
Write your hypothesis with an “if…
then…because” statement. The IF
discusses the independent (manipulated) variable and the THEN describes how it
affects the spread of the disease.
Materials:
The
Habitable Planet simulator (http://www.learner.org/courses/envsci/interactives/disease/disease_help.php)
Procedure:
- Open the simulator by entering http://www.learner.org/courses/envsci/interactives/disease/disease_help.php
Or search for “disease lab simulator”
and select the link for www.learner.org
- You will need to set up your variables in the simulator
parameters: Set population mixing to none; countermeasure vaccination rate
to none. Record the values in the
control table. Make sure you select
Impfluenza for the disease to be tested.
- Run 10 trials for population density LOW. Record the sick days reported and # dead
in your data table.
- Reset after each trial before you run another
test. Record sick days and dead in
your data table. Calculate the
average sick days and deaths.
- Repeat steps 3 and 4 for both MEDIUM and HIGH
population density.

Problem:
How does change in receipt of
vaccination affect the spread of influenza in a population?
Hypothesis:
Write your hypothesis with an “if…
then…because” statement. The IF
discusses the independent (manipulated) variable and the THEN describes how it
affects the spread of the disease.
Materials:
The
Habitable Planet simulator (http://www.learner.org/courses/envsci/interactives/disease/disease_help.php)
Procedure:
- Open the simulator by entering http://www.learner.org/courses/envsci/interactives/disease/disease_help.php
Or
search for “disease lab simulator” and select the link for www.learner.org
- You will need to setup your variables in the simulator
parameters: Set population density to medium and mixing to none. Make sure
you select Impfluenza for the disease to be tested.
- Run 10 trials for vaccination rate LOW (10%). Record the population number in your
data table.
- Reset after each trial before you run another
test. Record sick days and dead in
your data table. Calculate the
average sick days and deaths.
- Repeat steps 3 and 4 for both MEDIUM (25%) and HIGH
(75%) vaccination rate.
- Answer the discussion and analysis questions.

Discussion and Analysis Questions:
1. How did
your independent variable (density and vaccination rate) affect the number of
sick days? Death toll?
4 Statements needed.
2. Is your
hypothesis supported? (Answer for both!)
3. Are your
results the same each time? How do the results compare to one another?
4. How will
the spread of disease in Montana compare to spread of disease in an area with
higher population density?
5. Should a
person who is ill go to school or the grocery store? Use lab data to support your answer.
6. Which
variable has the greatest impact on the spread of disease: population density or
vaccination rate?
