Air

    Air has no smell. Air has no taste.

    But when the wind blows, you feel it on your face.

    Look at a kite,

    Or a plane in the air.

    How do they stay there? They ride on air.

    How does a balloon

    Rise in the air,

    And lift people up?

    It uses hot air.

    We need air to breathe.

    We need air to survive.

    And when we breathe it,

    It keeps us alive.
