Let's solve the worksheet titled
"What's The Matter?" by identifying whether each item is a
solid,
liquid, or
gas. Here's the explanation and answer for each:
---
1. Milk – Liquid
Milk flows and takes the shape of its container, but it has a definite volume — this defines a liquid.
2. Cookie – Solid
A cookie maintains its shape and does not flow. It has a fixed shape and volume.
3. Oxygen – Gas
Oxygen is a colorless, odorless gas that fills any container it’s in and doesn’t have a fixed shape or volume.
4. Fish – Solid
A fish is made of tissues and body parts that hold their shape — it’s a solid object (even though it lives in water).
5. Pencil – Solid
Pencils are rigid and keep their shape. They don't flow or expand to fill containers.
6. Syrup – Liquid
Syrup pours and flows like a liquid, taking the shape of its container while maintaining volume.
7. Shampoo – Liquid
Shampoo flows out of the bottle and takes the shape of the container — it’s a liquid.
8. Carbon dioxide – Gas
Carbon dioxide is a gas at room temperature; it’s invisible and expands to fill its container.
9. Ice cube – Solid
Ice is frozen water and has a fixed shape and volume — it’s a solid.
10. Paint – Liquid
Paint can be poured and spreads out — it’s a liquid (though some paints may thicken over time).
11. Oil – Liquid
Oil flows and takes the shape of its container — it’s a liquid.
12. Salt – Solid
Salt is made of tiny crystals that retain their shape and volume — it’s a solid.
13. Water Vapor – Gas
Water vapor is the gaseous form of water — it’s invisible and fills space.
14. Gasoline – Liquid
Gasoline is a liquid fuel that flows and can be poured.
15. Helium – Gas
Helium is a noble gas used in balloons. It expands to fill its container.
16. Sand – Solid
Sand is made of small solid particles. Each grain keeps its shape, so overall it’s a solid (though it can flow like a liquid when poured, it's still classified as solid matter).

This worksheet helps students understand the three states of matter:
solids (definite shape and volume),
liquids (definite volume, no definite shape), and
gases (no definite shape or volume).
