Seventh Grade Students Learn Benefits of Soap

Rudy Brandl

Seventh grade science students took advantage of a timely opportunity to learn more about the benefits of using soap in an experiment designed to teach the scientific method. Four volunteers were asked to get their hands very "dirty" with a mixture of coffee grounds and oils and asked the question "What is the benefit of using soap when we wash our hands?" After creating their hypothesis, two volunteers got a drop of soap (experimental group) and two went without soap. 

The students saw clearly how the soap (a surfactant) helped the water adhere to the oil/coffee mixture to wash it more effectively. Andrea Barnett, teacher and Science Department Co-Chair, was also able to introduce some facts about the coronavirus, specifically about having a fat layer that is damaged by soap. She hopes this quick lesson served to illustrate and reinforce some important information to keep everyone safe.
