Why Does the Sky Change Color? – Atmosphere & Light Scattering for Kids

The scene is set on a bright, sunny hilltop with a split sky: one half is a bright blue day, and the other half shows a vibrant, glowing green Aurora Borealis over a snowy peak. In the foreground, Dr. Owl is pointing up at the sky with one wing while holding a shiny glass prism that is casting a small rainbow. Emma is looking up in awe through a large, slightly oversized magnifying glass. Ziggy the Robot is trying to catch the rainbow from the prism in a glass jar, with a funny, determined tilt to his square head.
