Key Concepts
Air is a mixture of gases
Air is a mixture of gases that surrounds the Earth. We cannot see it, but we can feel it when it moves. We need air to breathe and stay alive.

Air has weight
Air has weight, even though it is light. A balloon filled with air feels heavier than an empty one.
Moving air is called wind
Moving air is called wind. A gentle wind is called a breeze. A very strong wind is called a storm.
Air helps us breathe
Air helps us breathe. Wind moves things like kites, sailboats, and windmills. Air is also used to fill objects like tyres, balls, and balloons.
