📚 Topic Summary
Matter is all around us! It's anything that takes up space and has weight. In simple terms, it's what everything is made of! Matter exists in three main forms (also called states): solid, liquid, and gas. A solid has a definite shape and size, like a rock or a toy. A liquid takes the shape of its container, like water or juice. A gas spreads out to fill the space it's in, like air or steam. Understanding these states helps us understand the world a little better!
