The Importance of Learning about Rainbows
A rainbow is an everyday occurrence, but there is a lot that kids can learn with a rainbow theme!
The rainbow itself is a powerful illustration of reflection, refraction, and dispersion of light. Rainbows appear when water droplets are in the atmosphere, and when light shines on them just right, you can see the entire visible light spectrum.
That is an exciting sight for most kids, but you don’t have to *just* learn about the rainbow with a real rainbow.
Many kids are rainbow-obsessed, so rainbows are a fun tool for exploring other science themes.
