An Experiment To Prove The Power Of Handwashing By A Behavioral Specialist

A Science project in a classroom is the perfect example of why washing your hand is essential.

Jaralee Annice Metcalf, a Behavioral Specialist, at an elementary school, not a fancy CDC lab, explains how bacteria can spread with a simple classroom activity with some students. She asked several children with several levels of hand cleanliness to touch pieces of fresh white bread. One slice of bread was untouched and put into a bag.

One slice was untouched, another with unwashed hands, one with hand sanitizer, one that had washed their hands with warm water and soap. They even decided to rub a slice of bread on all their classroom Chromebooks.

Bare hands did not touch the bread in the untouched bag. It was moved directly from the bread packet into the ziplock bag. The bread was taken from the same loaf and touched at the same time, and then they placed into individual plastic bags. 

The class observed the bread in the bags for a course of a month.

All their Chromebooks are usually washed down, yet for this experiment, they were not. All laptops, computers have germs. The amount of bacteria on them is based on the individual people that use them. 

A reminder to you and your children, for that matter, everyone in your family, hand sanitizer is not an alternative to washing hands.

The bags in which the various slices of bread were placed were ziplock bags meant for raw meat, and they seal tight.

An impressive experiment to do at home with your children. Especially at this time when the world is going through these challenging times. 

Teach your kids the importance of washing their hands!!

Clean hands help avoid the spreading of germs. Clean hands help prevent infections because people frequently touch their mouth, nose, and eyes without realizing it.

Thanks to Jaralee Annice Metcalf  for the images.
