         What is the sky? Where is it? How high is it? What lies above the sky? I am sure you have often asked
    these questions. They are very difficult to answer, aren't they?
         If someone asks you:"What color is the sky?" I think maybe you will answer"Blue". I am afraid you are
    wrong. The sky has no colors. When we see blue, it is the sunlight that is shining on little bits of dust in the
    air.

    earth. Planes can't fly without air. They need air to lift their wings. Planes can't fly very high because as they
    go higher, the air gets thinner. If we go too high up in the sky, we find there is no air.
         Perhaps you can answer some of the questions now. What is the sky? Nothing. Where is it? It is all around
    the earth. The sky is a part of space.
