A window is like a hole in a wall that lets you see outside without going outside. Think of it like your eyes. Just like how your eyes let you see things around you, a window lets you see things outside from inside your house. And just like how you can close your eyes to block out light, you can close a window to keep out things like cold air or rain. Windows come in many shapes and sizes, and can be made of different materials like glass or plastic. They’re an important part of a house because they let light and fresh air come in, which can make your home feel more comfortable and cozy.
