How Stress Affects the Body
Experimental Procedure
Data Analysis
Body Temperature & Stress Level Changes
Materials
Basal thermometer
Test subjects
Computer
Stopwatch
Notebook for recording and analyzing results
Variables
Dependent variable: is the body temperature

Independent Variable: is the stress or more specifically the test given to create the stress.
Hypothesis
I think stress does affect body temperature. I think participants temperature will decrease after taking a timed math test.
Question
Does stress affect body temperature?

Stress stimulates the release of hormones that affect the body in a variety of ways. In this experiment, I will evaluate whether changes in body temperature can be detected when people are placed in stressful situations.

Abstract
My science experiment was to determine whether or not participant’s body temperature
changes when they were asked to take a timed math test. I think stress does affect body temperature. I was convinced that participant’s temperature will decrease after taking a timed math test. The variable in my experiment was the stress or more specifically the test given to create the stress. The way I measured the responding or dependent variable was by the body temperature.
The results of this experiment were using the data obtained from my hypothesis , which was correct; I asked people to take a timed math test to observe if their body temperature decreases. This experiment has proved that stress level rises after taking a timed test. Body temperature does decrease after taking a test, which is due to stress. Most of my test subjects resulted in a higher stress level and lower body temperature after taking a math test. In this experiment I evaluated whether changes in body temperature can be detected when people are placed in stressful situations.
#1
Design a very challenging test to give to your test subjects. For example, you could create a multiplication test with many questions and ask test subjects to complete the test in just five minutes. Tell test subjects that they will receive a reward if they are able to complete the test perfectly within the time frame.
Before starting the test, ask the participant to rate his or her stress level on a scale of one to ten.
Ask the test subject to sit quietly for five minutes before taking the test.
#4
Take and record the subject’s basal body temperature.
#5
Ask the test subject to take the test.
#2
#3
#6
Immediately after the test, repeat the basal body temperature measurement and ask the test subject to rate his or her stress level on a scale of one to ten.
#7
Repeat steps 2 to 6 with approximately ten test subjects.
#8
Analyze your results. Do you notice changes in your test subjects’ body temperatures after they took the challenging test? If so, how much did temperature change on average? Did test subjects who rated a higher increase in stress level exhibit larger temperature fluctuations?
Results
Using the data obtained my hypothesis was correct: asking participants to take a timed math test decreased their body temperature. This experiment has proved that stress level rises after taking a timed test. However, body temperature does decrease when one is taking a test, which is due to stress. Most of my test subjects resulted in a higher stress level and lower body temperature after taking a math test. Stress stimulates the release of hormones that affect the body in a variety of ways. In this experiment I evaluated whether changes in body temperature can be detected when people are placed in stressful situations.

The body temperature decreased after the test.
Stress level increased after the test.
