What are flaps?

Flaps are parts that can move or fold, just like the front of your jacket when you put it on.

Imagine you're wearing a coat with big pockets on the sides. When you lift your arms, those pockets kind of flap up and down, that’s what we call flaps! They’re not stuck; they can move freely because there's space between them and the rest of the jacket.

How Flaps Work

Flaps are usually attached to something bigger, like a bag, a coat, or even an airplane wing. When you push or pull on them, they move, just like when you open your lunchbox and the lid flaps up.

You can also find flaps on shoes, where you tie your shoelaces. Those little pieces of fabric that flap around are called flaps, too!

So next time you see something moving or folding, think about how it’s acting like a flap, just like your jacket when you wave your arms!
