Homeostasis Lab

This lab was conducted in search for gaining clarity on what certain conditions need to stay constant in order to maintain stable inner conditions and equilibrium. Homeostasis is the tendency toward relatively stable equilibrium between interdependent elements.  We observed perspiration levels, heart rate, body temperature, and skin coloring to see what was needed to maintain homeostasis.

To start this experiment, a student was picked and the rest of the students took data on her skin color, heart rate, BMP, body temperature, perspiration rate, and O saturation. After this data was collected, the student did jumping jacks for 2 minutes straight. After the 2 minutes were up, the student immediately sat down and the other students collected the data stated above. Once that was finished, the student started doing jumping jacks for another 2 minutes, and these steps continued until the student did a total of 6 minutes of jumping jacks, and 2 minutes after for rest.

This is me and sophia! (Im on the right, I was the one chosen to do the jumping jacks!)

Our experiment exposed the many different ways the body naturally tries to maintain homeostasis. The overall body temperature decreased as activity increased, because the body was actively trying to cool the temperature down to keep equilibrium. The perspiration level increased because the body was trying to evaporate water to also help cool the body down. The blood pressure and heart rate increased as well because as the body got more active, the muscles needed more nutrients faster so this process increased to help suit their needs. Overall it was a great lab that helped our group realize how complex our body is!

This is me after a 2 minute interval getting my heart rate checked!

  1. Dear Meaghan,

    You were such a good sport to perform the jumping jacks for your group! It’s surprising how taxing doing jumping jacks for 8 minutes can be. You did an excellent job of explaining the methods you used and supporting your conclusion with explanations for what you discovered. Your post would benefit from your data or graphs, so that your reading can see your data. For instance, how much did the heart rate increase?

    Looking forward to future investigations posts!
