What Do Germs Look Like – Science Activity for Kids

This post may contain affiliate links. See my disclosure .

Have you ever looked at germs under a microscope? It is eye opening. Teaching kids about germs is an important task. With that said, I’ll be straight up with you: my 3.5-year-old son likes to lick things. Disgusting, right? He will lick a doorknob, a bench, a window, a figurine, his brother, me, you name it. In other words, he is an oral sensory seeker for sure. With that said, how do we teach kids about germs without constantly hounding them? I figure a good starting point is to explore the question “What do germs look like?”

What Do Germs Look Like?

Today we were at a play structure and he licked a handle that most undoubtedly had oodles of germs on it.

I finally had enough and said to him:

“Do you know what germs are?”
“Yes, they can make me sick.”
“Well, some of them, yes.”
“Can we see germs, mama?”
“No, we can’t see them. That is what makes them even more dangerous to our bodies.”
“Well, what are they, mama?”
“They are bugs that get into your body and can make you very ill.”

What Do Germs Look Like?

Teaching Kids about Germs

At that moment, his face kind of twisted up. I could see his brain trying to wrap itself around bugs crawling from the handle into his mouth. At first, my stomach dropped thinking that “Do or Die” approach wasn’t the most appropriate. In other words, I don’t want to raise a person completely nuts about germs.

On the other hand, the more he knows, the more likely his behavior will change for the better. I just want him to understand germs, that they can be dangerous but that they can also that the “right kinds” of germs can actually HELP our bodies. So not all germs are bad.

He led the learning on this one. I can’t count on my hands the number of times we’ve converged on learning. Typically I have something in mind and he takes it in another direction, one for which I am often not prepared. However, today was different because we were on the same page.

As I cooked dinner (and by “cook” I mean re-heat pizza and cut up vegetables.), he began asking more questions:

“What do germs look like, mom?”
“Why can’t I see them?”
“If they are so small, why do they make me sick?”
“Can I see them with my magnifying glass?”

What are the four types of germs?

According to KidHealth.org, the four major types of germs are bacteria, viruses, fungi, and protozoa. Germs invade plants, animals, and people. However, sometimes germs can make us sick but not all germs are bad. I recently read an article that offered a visual of the germs on an 8-year-old boy’s hand. The growth took place over a number of days. The visual is striking and honestly made me gagged a bit. 

At first glance, your first thought is “MUST WASH HANDS NOW”, but here is the thing: not all the disgusting looking bacteria, yeast, and other fungi are bad for our bodies. In other words, as an example, bacteria help keep things in balance.  Good bacteria live in our intestines and help us use the nutrients in the food we eat and make waste from what’s left over. Furthermore, some of these germs are found naturally in dirt, such as a rod-shaped Bacillus, for example. With that said, many germs are indistinguishable. Therefore, the conclusion is to wash hands often and wash them well.

The Four Types of Germs

Bacteria are tiny, one-celled creatures that get nutrients from their environments in order to live.

Viruses need to be inside living cells to grow and reproduce. Most viruses can’t survive very long if they’re not inside a host, which is a living thing like a plant, animal, or person. Some viruses live for a short time on surfaces such as handles, knobs, and countertops. So, it is important to wash your hands often. 

Fungi are multi-celled plant-like organisms. Unlike other plants, fungi cannot make their own food from soil, water, and air. Instead, fungi get their nutrition from plants, people, and animals.  

Protozoa are one-cell organisms that love moisture and often spread diseases through water. Some protozoa cause intestinal infections that lead to diarrhea, nausea, and belly pain.

What Do Germs Look Like?

So, I pulled out my laptop and searched “germ images microscope images” Not only did we find lots of close up images of germs, but we also found some great germ learning tools.  I was able to introduce words like “bacteria”, “virus”, “protozoa” and “fungi” to him. We even began talking about the function of the immune system. KidsHealth.org has a nice little germ overview with audio.

Science Activity to Teach Kids about Germs

 So we had the images but how can we demonstrate further in a hands-on way what germs really do to within a person’s body. The good news is that there are several easy and concrete science experiments you can do with your preschooler to learn more about the impact of germs.

You can use yeast, actually, grow mold, use lotion and glitter or cooked rice to demonstrate how germs spread and how tough it is to get them out of our bodies and my favorite: Sprinkle black pepper (“germs”) in a bowl of water. The pepper will float. Then add a drop of dishwashing soap into the center of the bowl. Watch the soap “scare the germs away”.

Practical Life Activity

A great segue into the importance of handwashing. Creating a “hand washing accessible” environment that allows kids the freedom to wash their own hands is key to integrating this important habit into your home. There is a great hand washing guide on the Children’s Health Fund website. Print it out and place it in your home or classroom as a reminder for the child.

In the middle of examining germs on the internet, my son bolted to the bathroom screaming: “Mom, I gotta wash my hands with A LOT of soap.” I don’t want to completely freak him out but I think there is merit to helping him understand germs. There are good and bad germs.

Montessori believed that if a child understands the parts of a tree, an animal, etc then he will not only have an understanding of botany and zoology but that he will also gain respect for these real life things. If you understand how your body works and how food, etc impacts it, then you are more likely to care for yourself in different ways. At least that is what I believe.
