Does the sky just have a case of the blues?? Is that why it always has that blue color?!
Believe it or not, the blue color of the sky has to do with the light from the sun! Did you know that color comes from the energies of light? Beams of light contain different energies that our eyes then interpret as certain colors.
When the sun shines onto Earth and lights up the sky, it shines waves of energies containing lots of colors. Of all of these waves, the waves of the energies that we see as blue are the shortest. Because they are the shortest, these waves are the most effected by the particles in our atmosphere, which cause them to scatter around the sky more than any of the others!
This "covers" the whole sky in a beautiful blue color!

Exploration
Imagine what it would be like if the sky appeared as a color other than blue. What if it were purple or green most of the time, instead of blue? Draw a picture of what this might look like! Does it feel strange and different, or kind of neat and interesting?? Why do you think it feels that way?
