Here is a great and visual experience for you to discover the secret world of bacteria. They are beneficial to us, and we use them in many cooking recipes, for example. Watch how bacteria turn sugar into alcohol and carbon dioxide using a simple soda bottle and a balloon.
It’s a great way to identify which drinks have sugar and which don’t.
Gather all the requested materials
Pour the grenadine into the soda bottle.
In a glass of warm water, slowly dilute the dry yeast and mix gently with a spoon.
Pour your mixture into the soda bottle and immediately cap your bottle with a balloon.
Watch your balloon as time goes by.
After an hour, your balloon is already well inflated.
Your yeast is made up of bacteria, tiny living things. Bacteria digest sugar and release alcohol and carbon dioxide.
For this experiment to work, bacteria need to be awakened. That is why you add lukewarm water (35 ° C). At this temperature, they “wake up” and convert the grenadine sugar into carbon dioxide. That’s why you are looking at the moss. Your balloon is inflated with carbon dioxide produced by bacteria.
Yeast is also used to make bread. Likewise, they release carbon dioxide into the bread dough. The dough is said to “rise”. Thanks to them, your bread is light and fluffy.
Are bacteria fungi?
Yeast, or bacterias, is an organism made up of a single cell. Scientists call them single-celled organisms. You probably know bacterias are very small and invisible to the naked eye. They measure around 3 to 5 microns. So it would help if you had a microscope to see them. They belong to the mushroom kingdom.
They are found in the soil, sugary liquids (in fruits and flowers), and on the surface of plants and animals. A visible colony has at least 1 million cells.
Test your friends and family with this challenge on sugar-eating bacteria
You can challenge your family members, your friends or your teacher.
To do this, fill a glass with normal degassed (sweetened) Coca-cola and another with zero degasified coca. With the yeast, the flask, an empty soda bottle and lukewarm water, they will need to identify which glass the normal Coca-Cola was in.
