4. Experiment 1
A group of students performed an experiment to see whether doing jumping jacks for two
minutes would increase their blood pressure. They had five students perform jumping jacks for
two minutes and then measured their blood pressure. They repeated the experiment three
times. They analyzed their results, and since the blood pressure measurements were all above
the normal values you’d expect, they concluded that doing jumping jacks does increase blood
a. What was wrong with Experiment 1?
5. Describe three ways to prevent contamination of your sample when working with bacteria.
6. For each microorganism describe what it is, how it reproduces, if it can mutate, and using the
disease dictionary 1-3 illnesses it can cause.
What it is

campylobacter? Explain
8. Look at the left. A patient comes in with a
cough, fatigue, chills, stuff nose and body aches.
