How Do We Use Air?

Read about some different ways people use air.

Breathing

People need air to breathe. We breathe in to pull air down into our lungs. We push the air out of our lungs when we breathe out. We breathe fast when we run. Our body needs more air when we run.

Filling Tires

Bike tires and car tires are filled with air. People use a pump to push air inside tires. A tire gets flat when it has a hole in it. The air inside the tire goes out the hole. People glue a patch on the hole to cover it. Then they use a pump to fill the tire with air again.

Drying Hair

People use a hair dryer to dry their hair. The hair dryer sucks in cool air. Next, the hair dryer heats the air to make it warm. Then the hair dryer blows out warm air. Warm moving air makes hair dry quickly.

Gathering Leaves

Some people use a leaf blower to gather leaves. A leaf blower blows out air that pushes leaves. People use a leaf blower to push all the leaves to one spot. Then they put the leaves in garbage bags.
