Microbiology

Microbiology is the study of tiny living things that we cannot see with our eyes. Microscopes help us to see these living things, which are called microbes. Microbes are found everywhere; in the air, in water, in the ground, and even in us! Microbes can cause diseases, but some are also used to help us in many different ways, like making food and medicines.
