Why is the sky blue?

And why does it glow red, orange, and pink at sunset?

In this episode of Vikings and Volcanoes, we break down the science of light and the atmosphere to explain why the sky changes colour throughout the day. Learn how sunlight is made of different colours, how blue light is scattered by air molecules, and why red light travels farther at sunset.

Perfect for kids, families, classrooms, and curious minds, this episode uses clear explanations, visual comparisons, and a fun end-of-episode quiz to turn physics into something you can see every day.

An educational science podcast for children that makes big ideas simple, memorable, and fun.
