Students learn about different types of germs & bacteria!
In Science, our home-schooled children have been learning about different types of germs & bacteria.
Germs are tiny organisms. They are so small that they are not visible to the naked eye and can only be seen using a microscope.
Many germs are useful and keep our bodies healthy. Some types of germs are even used to make food like bread and cheese, or as medicine like antibiotics.
Occasionally, germs can make us feel poorly. Only certain types of germs can have this effect.
There are 4 main types of germ: Bacteria, Viruses, Fungi & Protozoa.
Bacteria are very tiny, one-celled organisms which need nutrition from their environment. Sometimes these nutrients are from the human body.
Bacteria produce toxins that cause cells to burst and release the key nutrients that they need.
Not all bacteria are bad, as our body is full of helpful bacteria that we need every day.
The children took part in a food related activity focusing on the explanation of different types of germs and how they affect us.
