This worksheet is designed to help students understand how matter changes state when different conditions are applied. Let's solve each puzzle step by step:
---
1. Ice + Sun = ?
-
Ice is solid water.
- When ice is exposed to the
Sun, it absorbs heat energy.
- As a result, the ice melts into liquid water.
Answer: Water
---
2. Water + Fire = ?
-
Water is in its liquid state.
- When water is exposed to
Fire, it absorbs heat energy.
- As a result, the water evaporates into steam (gaseous water).
Answer: Steam
---
3. Water + Freezer = ?
-
Water is in its liquid state.
- When water is placed in a
Freezer, it loses heat energy.
- As a result, the water freezes into solid ice.
Answer: Ice
---
4. Steam + Cloud = ?
-
Steam is water in its gaseous state.
- When steam comes into contact with a
Cloud, it cools down and condenses into liquid water droplets.
- These water droplets form clouds or can eventually fall as rain.
Answer: Water
---
Final Answers:
1. Ice + Sun =
Water
2. Water + Fire =
Steam
3. Water + Freezer =
Ice
4. Steam + Cloud =
Water

Explanation of Matter Changes:
-
Melting: Ice → Water (solid → liquid)
-
Evaporation: Water → Steam (liquid → gas)
-
Freezing: Water → Ice (liquid → solid)
-
Condensation: Steam → Water (gas → liquid)
These processes demonstrate how temperature and pressure affect the state of matter.

Summary:
The completed worksheet should look like this:
```
Ice + Sun = Water
Water + Fire = Steam
Water + Freezer = Ice
Steam + Cloud = Water
```
Final Answer:
\boxed{Water, Steam, Ice, Water}
