Classroom Experiment Shows the Importance of Hand-Washing

Each year as the temperature starts to drop, discussion surrounding flu and cold season starts to rise.

From October to March there is a constant battle to prevent the spread of germs, and there’s one sentiment that you hear echoing off the walls, everywhere: go wash your hands.

A science teacher has decided to make an experiment and show his class how disgusting the germs are, and how important it is to wash your hands.

An Eye-Opening Experiment

Jaralee Annice Metcalf’s photographs of a science project she performed with her class, has gained more than 8,000 comments and 59.000 shares.

The experiment included five pieces of ordinary white bread. Each piece was touched with unwashed hands, one with washed hands with soapy water, and one with sanitized hands. The fourth slice was untouched, and the last piece was rubbed on all the chromebooks the students had in their classroom.

The results were surprising, and disgusting at the same time. Every slice of bread (even the one that was touched with sanitized hands) grew a certain amount of mold over the course of 3 weeks, except for one, the one that was touched with washed hands.

If the bread was exposed to moisture and air, this experiment may have gone a bit faster. The slices of bread that were exposed to different germs grew mold a lot quicker. And the ones that were touched by clean hands, weren’t exposed to the germs that caused the mold to grow quicker. -- Metcalf told Prents.com.

Flu Outbreak in the United States

As October comes, the flu season starts in the United States, and sometimes it can last until May. Even though the flu virus is circling around all year long, flu activity tends to peak from December to February.

There are four kinds of flu infections: A, B, C, and D. The types that people are worried about are A and B, which are the ones that cause occasional pestilences each winter. Flu C is generally only a mellow respiratory disease that doesn’t cause and pestilence, and D is predominantly found in cattle. 

This season’s cold virus can spread quickly, and 2017-2018 flu season was one of the deadliest on record. The Centers for Disease Control and Prevention (CDC) evaluated that in excess of 900 000 individuals were hospitalized and in excess of 80 000 individuals died from flu that year. 

The 2019-2020 flu season is as of now well in progress, thus far the CDC appraises that there have been at any rate 2.6 million flu ailments, 23 000 hospitalizations, and 1300 deaths because of the flu virus. 

How Does the Flu Spread? 

Most flu specialists concur that the flu infection spreads for the most part by beads of water made when somebody with this season’s cold virus hacks, wheezes, or talks. These beads make it into the mouths, noses, and can even be breathed in into the lungs of individuals close by. You can likewise get flu by contacting a surface that has the flu infection on it, and afterward contacting your mouth, nose, or eyes, anyway this is substantially less normal.

The issue with flu is that you can spread the infection before you even acknowledge you have it. While you are regularly generally infectious in the initial three to four days after seasonal flu begins, you may really have the option to taint others one day before manifestations create, and five to seven days after you become wiped out. 

A few people, particularly kids or individuals with debilitated immune systems, can stay infectious past the seven-day mark.

How to Wash Your Hands Efficiently

  • Scrub for about 20
  • Wash before you prepare or eat food, after you use the bathroom, or after changing your baby’s diper
  • If you’re taking care of somebody who is sick, wash your hands before and after being with them

If you can’t get to wash your hands in a toilet, use a hand sanitized, that’s the next best thing, but as we learned from Metcalf’s experiment, it is not the proper substitute for hand-washing.
