What is Air?

  • Air is the invisible mixture of gases that surrounds us.
  • We breathe air to help our bodies work and stay healthy.
  • Air is everywhere, and we can't see it, but we can feel it when it moves as wind.
  • Air also contains oxygen, which is important for animals and people to breathe.

Examples:

  • When you blow up a balloon, you fill it with air.
  • When you run fast and feel the breeze on your face, that is moving air.
  • Plants use air to make their food using a process called photosynthesis.

Fun Fact: Even though we can't see air, we know it's there because we can feel it, and animals and plants need it to live!
