More About microbes

Microbes have been around for a long time. They were first seen with a tool called a microscope. This tool helps us see tiny things. Some smart people found out how microbes work. They learned that some microbes can spoil food.

Microbes are part of our lives every day. They help make food like yogurt. But we must wash our hands to keep bad microbes away. This helps us stay healthy!

In the future, we will learn more about microbes. Scientists are still studying them. They want to find new ways to use good microbes to help us.
