WHAT ARE GERMS
Germs also called microbes, have to do with humans? Humans (and plants) are a place for germs to live. Think of it this way: humans need certain things to live, like oxygen, food, and water. If you take a human out of this safe, earthly environment and sent him or her to say, the moon, without food, water, and oxygen, he or she would not survive. Germs also need a certain environment in order to survive. And to some germs, the best place to be is inside the human body. Others thrive on our skin, or even just inside our mouths. Germs look for what they need to live.
One important thing to remember is that not all microbes are bad. Many are good and they help our bodies stay in balance. The bad ones, though, can make us sick. The four main types of germs are bacteria, viruses, fungi, and protozoa .
