A Teacher Performed an Amazing Experiment For Showing Her Students the ‘Power of Handwashing’

Sometimes a good example is all needed for a better education especially when it is to teach little children.  This is exactly what a teacher named Jaralee Metcalf teaching at a school located in Idaho did. What she did was an experiment for teaching little kids about the importance of washing the hands properly. And her little experiment has since then went viral and everybody has learned a good deal of washing properly before eating.

Today we are going to tell you the story of how a teacher performed an amazing experiment for showing his students the ‘Power of Handwashing’.


When the winter started, a behavioral specialist named Jaralee Metcalf working at the Falls Elementary School in Idaho shared the personal opinion as to how sick she would get often and how tired she was due to it. While the flu season was in full blow and she could do very little to stop the spread of the bacteria in her class, she still wanted to teach her students as to why and how the kids need to wash their hands properly for killing all the germs and bacteria.

The main focus of her experiment about “Power OF Handwashing”


For explaining to little students as to how important it is to wash your hands often and well, she came up with a fun little activity in the classroom.  She asked a few kids with different levels of the cleanliness of their hands to touch about 5 pieces of the white bread that had been taken all from a single loaf of bread. Then these bread pieces were placed inside separate plastic bags for observing what would happen to them in a 1-month time period.

Steps of this experiment


In her Facebook post, Jaralee explained, “We took fresh pieces of bread and then touched each of them”.

The first bread piece was rubbed all over the laptops in class. The second bread piece was the control piece that had not been touched and was placed in a plastic bag which had written over it “Fresh & Untouched”. 3rd bread piece was touched by the entire class with their unwashed hands. The 4th bread piece was the one touched by the whole class again but this time, everyone had their hands washed with soap and warm water. The 5th and last bread piece was touched after the kids cleaned their hands with the hand sanitizer,

The slice that was wiped over Laptops


After 1 whole month, the bread piece that was rubbed over laptops was the one that was worse than all the other specimens. The teacher then explained to the kids that while the school sanitizes their laptops, they had not sanitized these laptops for this project.

The one touched after whaling hands with Soap and Warm Water


The only piece of bead that did not show any signs of bacteria was the one that was touched by kids after they washed hands with soap and warm water. This experimental piece of bread showed as to why kids must always wash their hands before eating.

Bread slice touched with Dirty hands


The bread piece that was touched by the entire class with unwashed hands showed clear and different types of mold growth on it after one month. Seeing the bread was enough to learn what went wrong with it.

The bread piece touched after cleaning hands with Hand sanitizer


The last bread piece which was touched after the entire class cleaned their hands with hand sanitizer showed the most unusual results. This bread piece also showed signs of bacteria. This proved that hand sanitizers were not the ideal replacement for washing hands properly.

These results were then posted by Jaralee on her Facebook account. The post has been viewed since then for almost 70K times. Now this simple yet educating little experiment has spread to nearly hundreds of schools and also families are suing it to teach their kids at home as well the ‘Power of Handwashing’.
