Gather data: Fill in the first line of the data table below.
Then, use the same procedure to test the effect of each of the following factors. Click Reset between each trial. Record the initial and final body temperatures in the table below. (Leave the last column blank.)
Set the Exercise level to 70%. (All other settings in default position.)
Click Reset. Set the Sweat level to 70%. (All other settings in default position.)
Click Reset. Below Body position, click Shivering. (Other settings in default mode.)

Analyze: To determine the effect of a factor on body temperature, compare the final body temperature with that factor to the final body temperature while standing still. Based on this comparison, fill in the last column of the data table.
A. Which factor raised body temperature the most?
B. Why do you think this process raises body temperature?
C. Which factor lowered body temperature the most?
D. Why do you think this process lowers body temperature?

To determine the effect of each factor on body temperature, compare the final body temperature with that factor to the final body temperature while standing still.
A. The factor that raised body temperature the most is sweating.
B. Sweating raises body temperature because when sweat evaporates from the skin, it helps to cool down the body. This cooling process requires energy, which is generated in the form of heat, thus increasing body temperature.
C. The factor that lowered body temperature the most is shivering.
D. Shivering lowers body temperature because when the muscles shiver, they generate heat as a byproduct of the muscular contractions. This heat generation helps to warm up the body, thus lowering body temperature.

To fill in the first line of the data table, follow these steps:
1. Set all the settings to their default position.
2. Click on the "Reset" button to clear any previous data.
3. Leave the "Exercise level" at 0% or default position.
4. Record the initial body temperature in the "Initial body temp." column.
5. After one hour, measure the body temperature again and record it in the "Body temp. after one hour" column.
6. Leave the "Effect of factor on body temperature" column blank for now.
To test the effect of each of the following factors, follow these steps:
1. Click on the "Reset" button to clear the previous data.
2. Adjust the specific factor you want to test while keeping all other settings in their default position.
3. Record the initial body temperature in the "Initial body temp." column.
4. After one hour, measure the body temperature again and record it in the "Body temp. after one hour" column.
5. In the "Effect of factor on body temperature" column, analyze the difference between the initial and final body temperatures and note the effect of the specific factor on body temperature.
Repeat these steps for each factor you want to test, including standing still, exercising, sweating, and shivering. Make sure to reset between each trial and adjust the specific factor while keeping other settings in the default position.
