Bacteria From My Bellybutton & More

Hello all!

Today I bring you a bacteria focused experiment that I conducted at home, and you can too! This activity demonstrates the importance of personal hygiene and good cleanliness!

I bought a bacteria growing kit from Kitchen Chemistry on Ebay and you can find more about conducting such experiments from here and here.

The kit I purchased contains nutrient agar, petri dishes, and sterile inoculation loops. Following the instructions, I heated the nutrient agar and distributed the solution between petri dishes. I labelled the dishes and left the solution to set. To avoid contamination I used one inoculation loop per surface swabbed. I swabbed a variety of things, including my phone, my Snowy toy dog, and even my bellybutton. With each contaminated inoculation loop, I rubbed it lightly in a zigzag motion over the agar. Another thing to add is to be careful not to leave the lid off for too long, as the dish might get contaminated by airborne particles.

Next, I sealed the lids with tape, popped them in a cardboard box and left them in a warm place to encourage them to grow.

In only a few days, I noticed some major changes to a couple of the petri dishes!

LOOK AT THE BELLYBUTTON PETRI DISH!!! I’m amazed and aghast at the same time! The same goes for my phone too!

Now let me clarify that I am a CLEAN person. I shower daily, always wash my hands, etc. But I never thought to clean my bellybutton! I did read in one study, that scientists swabbed sixty belly buttons and identified one thousand four hundred and fifty-eight new species of bacteria! One volunteer’s belly button held bacteria that had only been found in soil from Japan, where the volunteer had never been!

It’s safe to say that I have since paid special attention to cleaning my bellybutton and my mobile phone.

As for the other petri dishes there either has been tiny changes or no noticeable changes. I will continue to grow the bacteria and share with you the future findings!

There are harmful bacteria out there that can make us ill, so it is important to practice good hygiene, cook food thoroughly, and overall maintain a clean environment. However, there are also friendly and useful bacteria that perform important functions in our bodies and in the world. For example, there are bacteria in our large intestines that break down food our bodies can’t digest, allowing our intestines to absorb the nutrients from our food. Furthermore, we use bacteria to turn milk into a variety of dairy products such as cheese and yoghurt.

I hope you enjoyed this post on growing bacteria. Make sure to subscribe to this blog to get future updates! Furthermore, you can pre-order a copy of Microbes at Waterstones, Amazon or through my publishers, Thunderstone Books.

Until next time!

You can pre-order Microbes!

For all you eager beavers, you can pre-order Microbes! It’s available to purchase from Waterstones, Amazon, and my publisher Thunderstone Books. The book will be released December 1st.

This book would make a super duper Christmas present for children 8+ or for any science-lover! If you wish to find out more about Microbes, please see below a review from the blog “The Picture Book Review“.

Microbes is a super fun and fantastically illustrated picture book that gives you tons of information about the crazy and amazing world of microbes!

The artist and author, Amy Gallagher, makes learning about the world of microscopic organisms interesting, funny, engaging, and memorable.

In this nonfiction picture book, information about six different types of microbes: bacteria, viruses, fungi, algae, archaea, and protozoa, is presented in an enthusiastic and playful fashion. She makes these microbes down right adorable.

What microbes are and how they function goes in-depth enough in some areas for middle and high school students, giving me flashbacks to AP Biology, but is presented with such humor and charm that my young sons 1) sits through multiple readings 2) talk to people in line at the grocery store about microbes now and 3) will randomly ask me questions from this book. It’s a fantastic book to read as cold and respiratory illness season is upon us, giving us tools to explain and understand what is going on inside our bodies as we try to prevent, fight off, and recover from illnesses.

Gallagher begins by doing an impressive job of explaining that microbes are everywhere, inside our bodies, on the food we eat, the air we breathe, on the things we touch, without ever giving that sinking, creeping feeling that can sometimes come with learning this information. It’s always friendly and upbeat. She shows us how important microbes are and makes us aware of how much we owe them. The book then addresses the six types of microbes beginning with the ones we have the most information about (bacteria and viruses) to the ones we have the least information about (archaea and protozoa).

In bacteria, Gallagher breaks down the five groups according to their shape (which I distinctly remember being on a high school test once) giving them adorable faces and including effortlessly memorable, easier was to remember them. With younger children, you’ll want to stop at times and give more explanation to certain terms and ideas that are mentioned in this book, but middle grade children will most likely will have at least been introduced to concepts such as nucleus, organelles, membranes, and DNA. Fun and relatable stories are interspersed between factual information giving it a good balance in tone and information. Antibiotic resistance and binary fission are excellently introduced and explained.

In viruses, we learn why hand washing is so important, why we don’t use antibiotics for viral infections, and that vaccines help our bodies build immunity to viruses. You’ll actually feel sympathy for a host cell as you read about how viruses invade, replicate, and then bud from it. You’ll root for and learn about what makes up your immune system as you watch it battle virons. My kids thought this was so awesome. “We have warriors in our body! Epic Cool!” – to quote the three-year old.

In fungi, we’re introduced to the wide variety of organisms that are included in this category from mushrooms to yeast to mold. This section highlights that fungi can range from single-celled organisms to multicellular clusters, and that we can mainly find them in dirt and plants.  We learn how some of them travel and disperse and that yeast have a couple different ways to reproduce. We’re shown how common fungi is in our daily life from bread to beer to mushrooms.

In algae, the topic of where we can find algae and its crucial role in producing the vast majority of air we breathe is introduced. Gallagher explains what chlorophyll is, where algae gets is colors, the basics of how algae forms together to make more complex structures, and even how we use the outer cell walls of microscopic algae in our daily life. You’ll never quite look at your toothpaste the same again.

In archaea, we learn how scientists used to call them “weird bacteria,” how they help keep our clothes clean, their three main types and sub-types, the types of environments that they can exist in that other organisms cannot, and how we’ve recently learned that they are basically everywhere.

In protozoa, we find out that they’re mainly here to eat other microbes. We learn about the sizes, structures, and movement methods of ciliates, flagellates, and protozoa in an accessible and engaging way.

22 terms are color coded and clearly defined in the glossary at the end. The final pages includes a visual recap of the six different types of microbes that is especially excellent for those who use images for memory hooks.

Microbes is an impressive general overview about the world of microscopic organisms. The illustrations are charming, adeptly utilize humor, and appeal to a wide variety of ages. It also excellently highlights important concepts of microbes. The information is organized, interesting, relevant and generates an enthusiastic energy to ask more questions and learn more. It’s a win!
