How Does The Real Reason Leaves Change Color In the Fall Work?

Leaves change color in the fall because they stop getting food from their tree and start showing off their hidden colors.

Leaves are like little chefs, they cook food using sunlight, water, and carbon dioxide. During summer, they work hard to make green food, which is why leaves look green. But when days get shorter and colder, the tree tells the leaf, “It’s time to rest.” So the leaf stops getting new food.

When leaves stop working, the green food starts to disappear. But they still have other colors hiding inside them, like yellow, orange, and red. These colors were always there, but the green covered them up.

It’s like wearing a green shirt over a colorful outfit, when you take off the green shirt, everyone can see your cool clothes underneath!

So, as leaves rest, they show their hidden colors until they finally fall from the tree. That's why we get to enjoy all the pretty colors in the fall!
