Matter

Okay kiddo, let's talk about matter! Matter is everything you can see, touch, or feel around you. Your toys, your food, your pets, and even yourself are made up of matter.

Now, matter is made up of tiny, tiny particles called atoms. Think of atoms like little building blocks. These atoms can join together to form different things, just like how you can use your blocks to build a tower or a castle.

There are lots of different types of matter, or things made up of atoms. Some, like water or air, are called gases. Others, like a rock or a toy car, are called solids. And there are things like milk or honey that are called liquids.

Now, matter can change from one form to another. For example, if you heat up ice, it will turn into water. And if you heat up water, it will turn into steam, which is a gas. But no matter what form matter is in, it always has mass and takes up space.

So, to sum it up, matter is everything we can see and touch around us, made up of tiny building blocks called atoms, and can exist in different forms like solids, liquids, and gases.
