Why is grass green?
Sunlight may look white, but it is really lots of colors, all traveling together.
Inside every blade of grass lives a tiny helper called chlorophyll.
It grabs red light and blue light and uses them to make the plant's food.
But green light? Chlorophyll doesn't grab it as much,
so green bounces right off the grass and zips straight into your eyes.
And that is why grass looks green.
Fun fact, in autumn, some trees make less chlorophyll.
The yellow and orange colors hiding inside finally get to glow.
Pine trees are different.
They keep their green needles all winter long, even when their growing slows way down.
So, next time you see green grass, you're seeing the color it bounced right back to you.
