Interactive worksheet teaching children about the states of matter and phase changes with engaging visuals and activities.

Let's solve the problem step by step based on the image provided.

Understanding the Task

The worksheet is about changing states of matter. It explains four key processes:
1. Melting: Solid → Liquid (heating)
2. Freezing: Liquid → Solid (cooling)
3. Evaporation: Liquid → Gas (heating)
4. Condensation: Gas → Liquid (cooling)

We are given four pictures and need to match each picture with the correct change of state using dotted lines.

Analyzing Each Picture

#### 1. Snowman melting in the sun
- The snowman is made of solid ice.
- The sun (heat) is causing it to turn into liquid water (dripping).
- This is melting.
✔ Answer: Melting

#### 2. Kettle with steam coming out
- The kettle has boiling water, which turns into water vapor (gas).
- This is evaporation.
✔ Answer: Evaporation

#### 3. Open freezer with ice cubes inside
- The freezer is cold, so liquids (like water) turn into solid ice.
- This is freezing.
✔ Answer: Freezing

#### 4. Plastic bottle with water droplets on the outside
- The bottle is cold, so water vapor in the air cools down and turns into liquid droplets on the surface.
- This is condensation.
✔ Answer: Condensation

Matching the Dotted Lines

Now we connect each image to the correct term:

- Snowman → Melting
- Kettle → Evaporation
- Freezer → Freezing
- Bottle with droplets → Condensation

---

✔ Final Answer:

Trace the dotted lines as follows:
- Snowman → melting
- Kettle → evaporation
- Freezer → freezing
- Bottle → condensation

---

🌟 Explanation Summary:

- Melting: Solid (snow) → Liquid (water) due to heat.
- Evaporation: Liquid (water in kettle) → Gas (steam) due to boiling.
- Freezing: Liquid (water) → Solid (ice) due to cold.
- Condensation: Gas (water vapor) → Liquid (droplets) due to cooling.

This matches all the scientific concepts shown in the worksheet!
