What are windows?

Windows are openings in walls that let light and air come in, just like the door to your room lets you go in and out.

Imagine you're sitting inside a cozy house on a bright sunny day. The windows are like big, clear doors, they’re not for walking through, but they let the sunshine pour in, making everything feel warm and cheerful. You can see outside through them too, just like looking through your toy bin to see what’s inside.

Windows are made of glass, which is a hard, smooth material that doesn’t get broken easily. The glass is held in place by a frame, think of it like the border around a picture. When you open a window, you can feel the breeze coming in, and sometimes you hear birds singing outside.

Some windows can be opened all the way, while others just lift up slightly. They help keep your house cool in summer and warm in winter, just like a blanket keeps you cozy at night.
