What is in a sand castle? Millions and millions of tiny grains of sand. The many grains of sand are packed together to make a single shape, like a castle with towers, walls, and bridges.
And what are you made of? Millions and millions of tiny bits, each one even smaller than a grain of sand. You and everything around you – people and animals, cars, rocks, water, and even the air – are made of tiny bits that are put together in different ways.
These bits are called atoms. Atoms are much smaller than a grain of sand. In fact, they are so small that you can’t see them. But if you could see them, you would find that these tiny atoms are made up of even smaller pieces. Even though atoms are so small that you can’t see them, they still have weight, and they take up space. They are tiny bits of matter. Everything that is matter – even you – is made up of tiny atoms.
