See if you can find the hidden microbes on each coloring page!

Microbes are singled-celled organisms that are invisible to the eye. But some can be seen with microscopes . They’re the oldest form of life on Earth .

Microbes are all over the surfaces of your house, on your skin, and in the air you breathe. Right now, trillions of microbes are living in your body! Don’t worry, while some are “germs,” most microbes are harmless to humans.
