As cold and flu season approaches I like to work in some activities that teach the kids why proper handwashing and other hygiene practices are. The Glitter Germ Experiment helps kids to actually be able to see the “germs” and give them a more concrete understanding of how handwashing and germ prevention work. It can be hard especially for smaller children for them to understand that even though you can’t see them germs are everywhere!
Glitter Germ Experiment Supplies
- A shallow dish
- Blue dish soap
Glitter Germ Experiment Directions
Pour water into the shallow dish nearly to the edge.
Sprinkle glitter generously over the surface.
We did this experiment 2 ways, squirting soap directly into a mass of glitter floating on the water then we also coated a finger in soap and tried to touch the “germs”.
The coolest thing that really catches the kids interest is how when soap is added to the water the germs (glitter) quickly moves away. The more soap the faster the reaction.
This fun simple experiment can be done over and over.
Next, we went to the sink and practiced good handwashing practices
Using soap not just water, rubbing between fingers, all the way to the wrist and making sure it was long enough. We sing our ABC’s twice as we wash to make sure that they are nice and clean.
Some questions to ask about germs
What is a germ?
How do they get on your hands?
How do you get them off?
Why do I need to wash my hands?
What does a germ look like?
Are all germs bad?
Find some videos so you can see what germs actually look like and how humans have to use microscopes to see them because they’re so small.
Talk about different illnesses that can be caused by bacteria such as colds, strep infections, E. coli and salmonella.
I like food examples because it lets them know that germs are all around us. But we cook our meat thoroughly to ensure we kill the bacteria so we can have dinner. And if food isn’t cooked properly, that’s who we get food poisoning.
It’s important to let our kids know that there is good and bad bacteria and each one has a job to do.
