Why is the sky blue?


I got into this while reading a book. Figured I’ll have to explain this one pretty soon, so thought I might as well be prepared. the book, A More Beautiful Question: The Power of Inquiry to Spark Breakthrough Ideas, provides an explanation. Here’s my version of it.

Science of why the sky is blue:

a) White light we see is composed of various colours. refraction experiments. Think prisms and rainbows.

b) But why blue and not other colours? Why does more blue light get refracted into our eyes than other colours?
Blue light scatters more due to gas molecules in the air.

c) Our eyes are also more sensitive to blue…

So the next time your child asks you why the sky is blue, now you know.

Good luck figuring out how to say this simply…
