Tell the story of why the sky is blue
The sky is blue because of the way the atmosphere scatters blue light from the sun. Short-wavelength blue light scatters more easily than other colors of light, which is why we see it from the bottom of a calm lake and why the sky appears blue.
The sky is blue because the particles in the atmosphere scatter short-wavelength blue light from the sun more effectively than other colors. This is why the sky appears blue from the ground.
