Homeostasis Lab

Homeostasis is when the body attempts to keep everything constant or balanced. The human body has many methods to maintain the same temperature, water levels, and even glucose levels no matter what environments it is in. In this lab, we evaluated the conditions that need to stay constant which allows the body to maintain balanced levels. This lab also shows how organisms maintain balances levels while living in constantly changing environments.


At the beginning of this experiment, begin by taking all of the students initial levels and record them in your table. Have the student jump for about two minute intervals for about six minutes total. After each two minute interval, measure all the student’s levels. Begin by taking their temperature by inserting a thermometer under the students arm. Next, place the blood pressure monitor onto the student’s right wrist and at the same time place the pulse oximeter onto the opposite hand on their index finger. Once you have completed these steps, have the student count how many breaths they take in ten seconds. Record all data in table.


After completing the experiment, we discovered many methods the body uses to maintain homeostasis. We found that as physical activity is increased their levels also increase. As they continue to exercise their perspiration levels increase, their blood pressure levels increase, their heart rate increase, their breathing rate increases. However, their temperature decreases due to the body attempting to stay cool by increasing their perspiration levels.

One thought on “Homeostasis Lab

  1. Dear Krystal,

    I enjoyed your post and your original media! You clearly described the methods followed in this lab, but it would be helpful to include your data table or graphs so that your reader can visualize your data. Also, an explanation of why you saw the changes in your subject’s readings would be informative (i.e. why did heart rate increase?). Why do you think their surface body temperature decreased while most of their other vitals increased?

    Looking forward to your next lab post!
