Solid, Liquid or Gas worksheet - Free Printable

Let’s go through each item one by one and decide if it’s a Solid, Liquid, or Gas.

---

Step 1: Understand the states

- Solid = has a fixed shape, doesn’t flow (like a rock or brick)
- Liquid = flows, takes the shape of its container (like water or syrup)
- Gas = spreads out, fills space, often invisible (like air or smoke)

---

Step 2: Go through each item

#### Row 1:
1. pancake syrup → Liquid (it pours!)
2. smartphone → Solid (you can hold it, it keeps its shape)
3. guide dog → Solid (it’s a living animal — made of solid parts)
4. air → Gas (invisible, fills space)
5. teddy bear → Solid (plush toy, holds shape)
6. Legos → Solid (plastic blocks, hard and shaped)

#### Row 2:
7. Coke → Liquid (it’s a drink in a bottle)
8. oxygen tank → The *tank* is solid, but the *oxygen inside* is gas → We’ll classify based on what’s being shown — the tank contains gas, so we’ll say Gas
- But wait — the image shows the whole tank. In science class, when they show an oxygen tank like this, they usually mean the *content*, which is gas. So → Gas
9. liquid → This is labeled “liquid” and shows water flowing → Liquid
10. blow → Shows a person blowing air → that’s moving gas → Gas
11. smoke → Smoke rises and spreads → Gas
12. liquid → Again, shows water in a glass → Liquid

#### Row 3:
13. smoke → Same as before → Gas
14. steam → Steam comes from boiling water — it’s water vapor → Gas
15. clouds → Clouds are made of tiny water droplets or ice crystals, but they float and spread → In elementary science, clouds are often treated as Gas (though technically they’re liquid/solid suspended in air). For this level, let’s go with Gas
16. coffee with milk → It’s a drink → Liquid
17. rock → Definitely Solid
18. baseball → Hard, round, holds shape → Solid

Step 3: Group them

#### Solid:
- smartphone
- guide dog
- teddy bear
- Legos
- rock
- baseball

#### Liquid:
- pancake syrup
- Coke
- liquid (first one)
- liquid (second one)
- coffee with milk

#### Gas:
- air
- oxygen tank (content)
- blow
- smoke (first)
- smoke (second)
- steam
- clouds

Wait — let’s double-check “oxygen tank”. If the question is about the object shown, it’s a metal tank → solid. But in science worksheets like this, when they show an oxygen tank with a label, they usually want you to think about what’s *inside*. Since it says “oxygen tank”, and oxygen is a gas, we’ll keep it as Gas.

Also, “clouds” — some might argue they’re not pure gas, but for K-5 science, they’re grouped under gas because they float and fill the sky.

Final Grouping:

✔ Solid:
smartphone, guide dog, teddy bear, Legos, rock, baseball

✔ Liquid:
pancake syrup, Coke, liquid (x2), coffee with milk

✔ Gas:
air, oxygen tank, blow, smoke (x2), steam, clouds

That’s 6 solids, 5 liquids, 7 gases.

Let’s count the items:
Row 1: 6
Row 2: 6
Row 3: 6
Total = 18 items.

Our groups:
Solid: 6
Liquid: 5
Gas: 7
→ 6 + 5 + 7 = 18 ✔️

Perfect.

Final Answer:
Solid: smartphone, guide dog, teddy bear, Legos, rock, baseball
Liquid: pancake syrup, Coke, liquid, liquid, coffee with milk
Gas: air, oxygen tank, blow, smoke, smoke, steam, clouds
