Teacher's Moldy Bread Experiment To Teach Kids The Importance Of Washing Your Hands

September 20, 2017


This is a shot of the experiment conducted by high school (high school!) Health Occupation teacher Donna Gill Allen while teaching her class about germs and how they spread. I imagine a lot of kids learned an important lesson from this experiment. And that lesson is if you're going to make a sandwich with dirty hands, eat it right away and don't put it in a bag or it will get gross.

Thanks again to Jody, who agrees life is too short to care about not eating off the floor.

    I call BS. This caught my attention when a teacher posted the same experiment with no results. I wouldn't have expected much results myself. Kids have germs on their hands, rarely do they have mold. The only thing that would create this dramatic of a result is if the kids touched the bread with "dirty" WET hands.

    I think a better experiment for high schoolers would be to tell them that the moldy bread is promiscuous and caught all the cooties.

    Seriously this is neat for elementary and maybe middle school kids... in the 50s. High school now? How about we teach them that the human body contains 90% microbial (essentially non-human) genetics? That our immune system, digestion, and overall health depends upon a diverse microbiome. And all those fucking antibiotics your doc gives you for every sneeze because you whine like a bitch about it, is RUINING EVERYTHING.

    Ahem. I might be a lab tech.

    What kills me are antibiotics given/asked for for viral infection... I mean, c'mon.

  • Doog

    This. So much this.

    I can almost understand a person asking for them if they are ignorant about what both antibiotics and viruses are/do, but even then the doctor should have a rational conversation with the individual informing them of their ignorance. A doctor actually prescribing them, asked for or not, is unacceptable and recklessly crazy stupid.

    People really need to become more informed, one way or another, for the good of all of mankind.

    Why did the third piece of bread get a completely different set of variables? The "Controlled" and "clean" breads get handled by one person the other bread gets handled like a cheap hooker in an orgy. The Scientific method was not followed here, this study would never be published.

  • Doog

    Exactly. Let all the kids handle the bread after washing their hands. Something tells me that this was not done for a reason. Either way though this is about as scientific as my anecdotal research into how many drinks it takes to make me 'feel' intoxicated regardless of time or type of drink.

    Speaking of, I believe I'm close to a breakthrough. I mean I'm at about the same amount of drinks as yesterday and I might be starting to feel something.

  • Forblat

    Now do another with clean hands and a little bit of moisture to show how the bread already had mold spores on it and it'll grow anyway

  • Bling Nye

    For sure; spoilage organisms don't really cause illness and pathogenic organisms don't really cause spoilage. While I totally agree with you about that, it's still a good "ah ha" moment of learning for the kids.

    ...until I just read it was in high school and not elementary school like I'd assumed. WTF? High schoolers should be streaking agar plates FFS, not playing with goddamn bread. :/

  • Jenness

    I too am horrified this is a HS experiment. Ever since 9/11 the entire education system purposefully handicapped our youth it seems.

    *when you find out your 6 year old has been washing his hands WITHOUT soap for the past 2 months*

  • FearlessFarris

    I'm always shocked by people in public restrooms who wash without soap. In a way, that's got to be worse than not washing at all.

  • Draco Basileus

    I'm always shocked by people in public restrooms who DON"T WASH THEIR HANDS AT ALL!

    I'm looking at you, Mr. Fancy Business Suit in Suite 1350. Just because you enjoy fondling your peen in bathroom doesn't mean that I have to "enjoy" it too by touching the same door handle on my way to freedom.

    TL;DR kids are moldy disgusting disease carriers.
