Solid, Liquid, Gas worksheet - Free Printable

Let’s go step by step to classify each item as solid, liquid, or gas.

We know:
- Solids have a fixed shape and volume. You can hold them, they don’t flow.
- Liquids take the shape of their container but have a fixed volume. They flow.
- Gases spread out to fill any space. You usually can’t see them (except sometimes like smoke or steam).

Now let’s look at each one:

1. Water – This is in a glass, it flows and takes the shape of the glass → Liquid
2. Cube – These are toy blocks with letters. They keep their shape → Solid
3. Water vapour – This is what comes out of a boiling kettle. It’s invisible gas that turns into steam you can see → Gas
4. Wood – A piece of wood keeps its shape, you can touch and hold it → Solid

Next row:

5. Smoke – Comes from fire or something burning. It floats and spreads out → Gas
6. Milk – Poured from a carton into a glass. Flows and takes the shape of the container → Liquid
7. Juice – Same as milk — poured, flows, fills the glass → Liquid
8. Ice – Frozen water. Hard, keeps its shape → Solid

Last row:

9. Brick – Heavy, hard, doesn’t change shape unless broken → Solid
10. Oxygen – We breathe it. It’s a gas in the air → Gas
11. Air – What we breathe every day. Invisible, fills rooms → Gas
12. Rain – Water falling from clouds. It’s liquid water → Liquid

✔ All checked and double-checked!

Final Answer:
water → liquid
cube → solid
water vapour → gas
wood → solid
smoke → gas
milk → liquid
juice → liquid
ice → solid
brick → solid
oxygen → gas
air → gas
rain → liquid
