Body Chemistry Experiment: Measure pH of Body
This is an easy experiment to learn about the chemistry of the body while you learn about pH.
The human body is made up of different elements. All elements have different pH ranges. Like elements, pH is measureable for the materials that make up the human body. Not all people have the same pH. In fact, each time you measure pH of body may vary by the day. In this experiment, we will measure pH of the body by testing saliva. **Follow all the manufacturer’s requirements for the pH test strips. Do not place the pH test strips directly in the mouth. If you are concerned about germs and have a fear that it may be too difficult to control kids performing the experiment, then this may not be the right experiment for your group**
From the measure pH body experiment, was the pH within a range of 7. Doctors expect a person’s body pH to be in the range of 7.3 to 7.4. The things that a person eats or drinks before the measurement, however, may skew the pH values. pH is the abbreviation for power of hydrogen. A pH of 7 is considered neutral. A pH higher than 7 is a base (or alkaline). A pH less than 7 is an acid. The human body is therefore slightly basic. Acidic foods like citrus, vinegar, and soda pop (carbonic acid) which were recently consumed may lower the pH of the saliva test results. If the person is sick or recently exercised, then the pH level may also be lower than the standard range.
