The Effects of Exercise on Homeostasis
|Student Name |Serena Gray |
|Date |09-07-2012 |
Objectives
Students will • Identify conditions that need to stay constant to keep the body in equilibrium. • Describe how organisms maintain stable internal conditions while living in changing external environments.
Materials jump rope/skipping rope thermometer stopwatch alcohol cotton balls
Background Exercise causes many factors of homeostasis to kick in to maintain internal equilibrium.
How exercise affects some of these factors can be determined by measuring and observing certain conditions of the human body. Some of these conditions are: • change in skin color on arms and face • perspiration level • external body temperature • breathing rate • heart rate
Prelab Notes 1. Working in groups of 3 or 4, select a student that will be able to jump rope well and will be able to maintain jumping for 8 minutes. The group member jumping will stop just long enough for the needed measurements and observations to be collected. 2. Record the resting observations and values of the person jumping rope (or doing jumping jacks) using the following measurements:
• skin color of hands and face (pale, pink, red) • perspiration level (none, mild, medium, high) • external body temperature (place the thermometer under the subjects arm pit for 1 minute; the thermometer should be directly against the skin) • breathing rate (count the number of breaths in 1 minute) • heart rate (find the pulse at the wrist and count the number of beats in 1 minute)
Procedure 1. Make observations and measurements of the person jumping rope while they are sitting
