A Teacher Did an Experiment to Show the Power of Handwashing, and You Can’t Stay Unimpressed

Sometimes a prime example is better than words — especially when it comes to explaining something to children. That’s exactly what Jaralee Metcalf, a teacher from Idaho, decided to do to show her pupils the importance of washing their hands properly. And now the whole world is following her example!

Here at Bright Side we were so impressed by how simple and clear this project was, that we couldn`t hold back from telling you about it.

At the beginning of winter, when flu season had just started, Jaralee Metcalf, a behavioral specialist from Idaho Falls Elementary School, shared that she was tired of always being sick. Although the spread of bacteria in her class was inevitable, she wanted to show the kids why they needed to wash their hands to kill germs.

To explain how bacteria spread and why it’s important to wash your hands well and often, Jaralee came up with a simple classroom activity with her students: she asked several kids with various levels of hand cleanliness to touch 5 pieces of white bread that were taken from the same loaf, at the same time. Then, they put the bread in individual plastic bags to observe what would happen over the course of one month.

“We took fresh bread and touched it.” — explains Jaralee in her Facebook post that has been shared about 70K times.

The first piece was rubbed on all of the classroom laptops. The second one was a control piece — it wasn’t touched, it was placed immediately in the plastic bag and labeled “Fresh & untouched.” The third piece of bread was touched by the whole class using unwashed hands. For piece #4 the whole class washed their hands with warm water & soap and, again, touched the slice. And for bread piece #5, they cleaned their hands with hand sanitizer and then touched it.

What do you think?
