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: Water
👉 Draw: A puddle or drops of liquid water in the box.

---

2. Water + Fire = ?

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

✔ Answer: Steam / Water Vapor
👉 Draw: Wavy lines rising from water (like steam) in the box.

---

3. Water + Freezer = ?

- Water is a liquid.
- The Freezer is cold (low temperature).
- Cold causes water to freeze and become ice (solid).

✔ Answer: Ice
👉 Draw: An ice cube or frozen block in the box.

4. Steam + Cloud = ?

- Steam is water vapor (gas).
- Clouds are made of tiny water droplets or ice crystals suspended in the air.
- When steam (water vapor) rises and cools in the atmosphere, it condenses into clouds.
- But here, we’re combining steam and cloud — this suggests more water vapor joining a cloud, which can lead to rain if enough condensation occurs.

However, since the question is about what happens when you combine them, the most logical result is that steam becomes part of the cloud, increasing its size.

But looking at the context of the puzzle (simple science), the intended answer might be:

✔ Answer: Rain (or Cloud)
👉 However, "Rain" is more accurate because clouds form from condensation, and if enough moisture accumulates, raindrops fall.

Alternatively, the process could just be Condensation → Cloud formation, so:
✔ Answer: Cloud (larger or more dense)

But given the sequence, Steam + Cloud = Rain makes sense as the resulting change.

But let’s think carefully:

- Steam (gas) → rises → cools → condenses → forms clouds.
- So adding steam to a cloud means more water vapor condensing, leading to rain.

✔ Best Answer: Rain
👉 Draw: Raindrops falling from a cloud in the box.

✔ Final Answers:

| Puzzle | Result | Drawing |
|-------|--------|--------|
| Ice + Sun | Water | Liquid droplets |
| Water + Fire | Steam | Rising wavy lines |
| Water + Freezer | Ice | Ice cube |
| Steam + Cloud | Rain | Raindrops falling from cloud |

📝 Summary Explanation:

This worksheet teaches phase changes of water:
- Melting: Ice → Water (heat)
- Evaporation: Water → Steam (heat)
- Freezing: Water → Ice (cold)
- Condensation & Precipitation: Steam → Cloud → Rain

Each combination shows how energy (heat or cold) changes the state of matter.
