Explain to a 2nd Grader why the sky is blue:

All objects have the ability to either absorb or reflect light. That determined their color. An object will absorb all colors, except for the color that it appears to be. It will reflect the color it appears to be. The sky is blue, because it absorbs all colors of light, except blue, and reflects blue instead.
