Ice, Water, and Steam: The Three States of Matter
Do you know that everything around us is either a solid, a liquid, or a gas? These are called the three states of matter. A solid, like an ice cube, keeps its shape. A liquid, like water, takes the shape of its container. A gas, like the steam from a boiling pot, fills up all available space. You can see this at home! When you freeze water, it turns into solid ice. When it melts, it becomes liquid water. If you heat it until it boils, it turns into steam, which is a gas. Isn't that cool?
