🔍 Worksheet Overview


This is a fill-in-the-blank activity that teaches students about:
- The three states of water: solid (ice), liquid (water), gas (steam).
- The changes of state between them: melting, freezing, evaporation, condensation.

The worksheet includes:
- A word bank with terms: *Boiling, Freezing, Condensation, Melting*.
- Diagrams showing transitions between states.
- Visuals: ice cubes, a puddle of water, and steam from a kettle.

🧩 Step-by-Step Solution



#### 1. Identify the States of Water
From the visuals:
- Left side: Ice cubes → Solid
- Middle: Puddle → Liquid
- Right side: Steam rising from kettle → Gas (Steam)

So:
- Top box (left): Ice
- Middle box: Water
- Top box (right): Steam

#### 2. Determine the Changes of State
Use arrows and word bank to label what happens between each stage.

##### 🔁 From Ice → Water
- Change: Melting
- Definition: Solid turns into liquid when heated.
- Fill in: Melting

##### 🔁 From Water → Steam
- Change: Boiling
- Definition: Liquid turns into gas when heated to boiling point.
- Fill in: Boiling

##### 🔁 From Steam → Water
- Change: Condensation
- Definition: Gas turns into liquid when cooled.
- Fill in: Condensation

##### 🔁 From Water → Ice
- Change: Freezing
- Definition: Liquid turns into solid when cooled.
- Fill in: Freezing

Final Answer Layout



| Diagram | State of Water | Change of State |
|--------|----------------|------------------|
| ❄️ Ice cubes | Ice | → Melting → |
| 💧 Puddle | Water | → Boiling → |
| ☁️ Steam | Steam | ← Condensation ← |
| (Back to water) | Water | ← Freezing ← |

> Note: The arrows show direction. So:
> - Ice → Water: Melting
> - Water → Steam: Boiling
> - Steam → Water: Condensation
> - Water → Ice: Freezing

📝 Explanation for Students



- Melting: Ice melts into water when heat is added.
- Boiling: Water boils into steam when it reaches 100°C.
- Condensation: Steam cools and becomes water droplets (like dew or fog).
- Freezing: Water turns into ice when cooled below 0°C.

These changes are physical changes, meaning no new substance is formed — just a change in state.
