What is matter in 5th grade science?

Matter is anything that takes up space and has weight. It makes up everything around us, like toys, water, and air. Matter can be in three forms:

1. Solid – Has a fixed shape, like ice or a rock.
2. Liquid – Takes the shape of its container, like water or juice.
3. Gas – Spreads out and doesn’t have a fixed shape, like air or steam.

Everything is made of tiny particles called atoms.
