What is Air Made Of?

Air is like a invisible blanket made up of tiny invisible friends that we can't see but feel every day.

Air is mostly made of two types of invisible friends: oxygen, which helps us breathe, and nitrogen, which is like the quiet helper in the group. Together, they make up most of what we call air.

Besides oxygen and nitrogen, there are also some other tiny friends that come along for the ride. These include carbon dioxide, which you might know from when you blow out birthday candles, and a little bit of water vapor, which is like the invisible mist that can make clouds or rain.

Sometimes, air has even more guests, like dust, pollen, or smoke, especially if it's been outside or near a busy street. These extra friends are why you might sneeze or cough when you're in a stuffy room.

So next time you take a deep breath, remember: you’re breathing in a whole crowd of tiny invisible friends!
