Discovering the World of Germs

In Pasteur’s time, many people believed sickness came from bad air or bad luck. Pasteur did experiments that showed tiny living things, called germs, could cause food to spoil and people to get sick. This idea became known as the **germ theory of disease**.

His work helped people understand why washing hands and cleaning tools are important. These simple habits saved many lives and are still used today.

Pasteurization: A Big Idea for Food Safety

One of Pasteur’s most famous ideas is called **pasteurization**. He discovered that heating liquids like milk and juice for a short time could kill harmful germs.

Thanks to pasteurization, food lasts longer and is safer to drink. Even today, many drinks are pasteurized using Pasteur’s method.

Pasteur cared deeply about helping others. He believed science should make life better for everyone.
