2nd Grade Science Worksheets On Matter - Free Printable

Let's go through this Physical Science: States of Matter worksheet step by step and solve each section based on the directions. Since this is a coloring activity, we'll identify which items in each row should be colored according to the instructions.

---

🔹 1. Color the items that show the process of a liquid to a gas.

This refers to evaporation or boiling, where a liquid turns into a gas (vapor).

Items shown:
- Pot with steam rising → ✔ Yes (liquid water boiling → steam)
- Snowman melting → ✘ No (solid to liquid, not liquid to gas)
- Mug with steam → ✔ Yes (hot liquid releasing vapor)
- Ice cube melting → ✘ No (solid to liquid)
- Kettle with steam → ✔ Yes (boiling water turning to steam)

✔ Color:
- Pot with steam
- Mug with steam
- Kettle with steam

🔹 2. Color the items that have stored energy.

These are objects that store potential energy (chemical, mechanical, etc.).

Items shown:
- Rock → ✘ No (unless it’s elevated, but no indication here)
- Battery → ✔ Yes (stores chemical energy)
- Plant → ✔ Yes (stores chemical energy via photosynthesis)
- Pencil → ✘ No (unless it's used for work, but not storing energy)
- Iron → ✘ No (not storing energy unless heated, but not indicated)
- Lightbulb → ✘ No (uses energy, doesn’t store it)

✔ Color:
- Battery
- Plant

> Note: Some might argue the rock has gravitational potential energy if it's high up, but since it's just a flat rock, likely not intended. The plant stores energy in its tissues (photosynthesis), so yes.

🔹 3. Color the items that are a solid.

Solids have definite shape and volume.

Items shown:
- Block → ✔ Yes
- Logs → ✔ Yes
- Cloud → ✘ No (gas/liquid droplets suspended in air — not a solid)
- Glass with liquid → ✘ No (the liquid inside is not solid)
- Ice cream cone → ✔ Yes (ice cream is a solid, even if soft)

✔ Color:
- Block
- Logs
- Ice cream cone

> Note: The ice cream is typically considered a solid in this context (frozen dessert). The glass is solid, but the liquid inside isn't; however, the whole object is not "a solid" — only the contents matter per instruction. So only color the solid parts.

🔹 4. Color the items that are a natural light source.

Natural = not man-made.

Items shown:
- Lamp → ✘ No (artificial)
- Sun → ✔ Yes (natural)
- Flashlight → ✘ No (artificial)
- Campfire → ✔ Yes (natural, from burning wood)
- Candle → ✘ No (artificial, though flame is fire — but candle itself is man-made)
- Lightbulb → ✘ No (artificial)

✔ Color:
- Sun
- Campfire

> Note: While candle flame is real fire, the candle is human-made, so usually classified as artificial. The sun and campfire (wood fire) are natural sources.

🔹 5. Color the items that are a gas.

Gases have no fixed shape or volume, fill containers.

Items shown:
- Balloon → ✔ Yes (if filled with air/heleium — assumed to be gas)
- Crumpled paper → ✘ No (solid)
- Spray can → ✘ No (contains gas, but the can is solid; not the gas itself)
- Paint can → ✘ No (liquid paint inside)
- Skateboard → ✘ No (solid)

But wait — the balloon is a container, but it contains gas. In such worksheets, balloons are often meant to represent gas (air/helium).

Also, spray can may be interpreted as containing compressed gas, but it's not *a gas* — it's a container.

So only:
- Balloon → ✔ Yes

Wait — let's look again:

- Balloon → ✔ Yes (filled with gas)
- Spray can → ✘ No (container)
- Paint can → ✘ No
- Skateboard → ✘ No
- Crumpled paper → ✘ No

But what about steam? Not shown here.

Only the balloon clearly represents a gas.

However, some interpretations:
- The crumpled paper could be mistaken for something else, but no.
- The spray can might be labeled as having gas, but unless it's spraying, it's not showing gas.

✔ Color:
- Balloon

> But wait — there's a cloud in the previous section. Clouds are made of tiny water droplets (liquid) or ice crystals (solid), not gas. Water vapor is invisible gas, but cloud is visible mist.

So no, cloud is not a gas.

Thus, only the balloon is a clear representation of a gas.
