Solids, Liquids, Gases worksheet - Free Printable

Let's go through each image in the worksheet and determine whether it represents a solid, liquid, or gas. I'll explain each choice briefly.

---

Row 1

1. Apple → Solid
*Explanation:* The apple has a definite shape and volume, so it is a solid.

2. Milk in a cup → Liquid
*Explanation:* Milk flows and takes the shape of the container, but maintains its volume — a liquid.

3. Table → Solid
*Explanation:* The table has a fixed shape and volume, made of wood (a solid).

Row 2

4. Pouring oil → Liquid
*Explanation:* Oil flows and pours, which is characteristic of a liquid.

5. Steam coming from a kettle → Gas
*Explanation:* Steam is water vapor — invisible gas formed when water boils.

6. Bottle of juice → Liquid
*Explanation:* The juice inside the bottle is a liquid, even though it's in a container.

---

Row 3

7. Soccer ball → Solid
*Explanation:* The ball has a definite shape and volume; it’s made of solid materials.

8. Plastic slide → Solid
*Explanation:* The slide is made of plastic and has a fixed shape and volume.

9. Water flowing from faucet → Liquid
*Explanation:* Water is a liquid that flows and takes the shape of the stream.

Row 4

10. Fog or mist → Gas
*Explanation:* Fog consists of tiny water droplets suspended in air, but the visible "mist" is often considered a mixture of liquid and gas. However, since fog is mostly water vapor (gas) with tiny liquid droplets, the main phase here is gas (water vapor). But if it's shown as clouds/fog, it's typically classified as gas in basic science.

11. Winter jacket → Solid
*Explanation:* The jacket is made of fabric and insulation — all solids.

12. Balloon (inflated) → Gas
*Explanation:* The balloon is filled with air (a gas), which expands to fill the space.

---

Row 5

13. Laptop → Solid
*Explanation:* The laptop is made of metal, plastic, and other solid materials.

14. Bubbles → Gas
*Explanation:* Bubbles contain air (gas) trapped in a thin film of liquid. The interior of the bubble is gas.

15. Glue bottle with glue oozing out → Liquid
*Explanation:* Glue is a viscous liquid that flows slowly.

---

Row 6

16. Ice cube → Solid
*Explanation:* Ice is frozen water — a solid state of matter.

17. Hand sanitizer bottle → Liquid
*Explanation:* The substance inside is a liquid, even though it's in a bottle.

18. Shoe → Solid
*Explanation:* Shoes are made of leather, rubber, etc., all solids.

---

Row 7

19. Cookie → Solid
*Explanation:* A cookie has a fixed shape and volume — it's a solid.

20. Cloud → Gas
*Explanation:* Clouds are made of water vapor (gas) and tiny liquid droplets, but in elementary science, they're generally categorized as gas (water vapor).

21. American flag → Solid
*Explanation:* The flag is made of fabric, which is a solid material.

📝 Summary:

- Solids: Apple, table, soccer ball, slide, jacket, laptop, ice cube, shoe, cookie, flag
- Liquids: Milk, oil, juice, water from faucet, glue, hand sanitizer
- Gases: Steam, balloon (air), fog/mist, bubbles, cloud

This classification helps students understand the three states of matter based on physical properties like shape, volume, and flow.
