Let's solve the "What's the Matter?" worksheet step by step. This activity is designed to teach how matter changes state (solid, liquid, gas) based on temperature and environmental conditions.

1. Ice + Sun = ?

- Ice is a solid form of water.
- The Sun provides heat (thermal energy).
- When ice is heated, it melts into liquid water.

✔ Answer:
👉 Draw: A puddle or droplets of water.
👉 Label: Water

---

2. Water + Fire = ?

- Water is in liquid form.
- Fire adds heat.
- When water is heated, it turns into steam, which is water vapor (gas).

✔ Answer:
👉 Draw: Steam rising from water (like bubbles or wavy lines).
👉 Label: Steam

---

3. Water + Freezer = ?

- Water is liquid.
- The Freezer is cold (low temperature).
- When water is cooled, it freezes into ice (solid).

✔ Answer:
👉 Draw: An ice cube or frozen block.
👉 Label: Ice

4. Steam + Cloud = ?

- Steam is water vapor (gas).
- A Cloud forms when water vapor cools and condenses into tiny water droplets.
- So, steam (water vapor) rising into the air can form clouds.

But here, we're combining steam and cloud — this suggests what happens when steam enters the atmosphere and becomes part of a cloud.

Actually, this one is a bit tricky because steam already becomes part of a cloud through condensation. But the puzzle shows:

> Steam + Cloud = ?

This could mean: When steam rises and joins a cloud, it contributes to the cloud’s formation.

So, the result is more cloud or rain if it condenses further.

However, since it's asking for a change in matter, and both are gases/liquids in suspension, the most logical outcome is that steam adds to the cloud, making it bigger.

But let's think about phase change: Steam (gas) → Cloud (tiny liquid droplets) = Condensation.

So, the final result is Cloud (more specifically, liquid water droplets in the air).

✔ Answer:
👉 Draw: A larger cloud or raindrops forming.
👉 Label: Cloud or Rain (if precipitation occurs)

But since the original inputs are steam and cloud, and clouds are made of condensed water vapor, the result is just Cloud — the steam becomes part of the cloud.

So best answer:
👉 Draw: A cloud with some added moisture or raindrops.
👉 Label: Cloud

✔ Final Answers Summary:

| Puzzle | Result | Drawing Suggestion |
|-------|--------|--------------------|
| Ice + Sun | Water | Puddle of liquid |
| Water + Fire | Steam | Rising vapor/waves |
| Water + Freezer | Ice | Ice cube |
| Steam + Cloud | Cloud | Larger cloud or rain |

🔍 Explanation:

This worksheet teaches the three states of matter and how they change:
- Melting: Solid → Liquid (Ice → Water)
- Evaporation: Liquid → Gas (Water → Steam)
- Freezing: Liquid → Solid (Water → Ice)
- Condensation: Gas → Liquid (Steam → Cloud)

These are all physical changes — no new substances are formed, just changes in state.
