They are all around us. They are everywhere we look and everywhere we go. They come in all shapes and sizes. Some are made by people, some are natural. Some are super ugly, others are simply beautiful. Do you need a few more clues to guess what they are?
We live in them, go to school in them, and drive in them. They protect our heads from nasty bike crashes, keep our feet dry on wet days, and make up the framework of our body. They are mountains, spider webs, ant hills, beaver dams, and trees. They include the unimaginably huge universe with its millions upon millions of galaxies and stars. They also include atoms which are too small to be seen with the naked eye.
Do you give up yet? They're all structures. Think of structures as a combination of parts that belong together. Take a look around you right now. How many structures can you see? A lot, right? Let's take a look at just a few of the millions of structures that surround us everyday.
