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 a freezer,
liquid water turns into
ice (solid).
- This happens due to
cooling.
- This is
freezing.
✔ Answer: Freezing
####
4. Water bottle with droplets on the outside
- The bottle is cold, so
water vapor in the air condenses into
liquid droplets on the surface.
- This is
condensation.
✔ Answer: Condensation

Matching the Pictures to the Correct Terms
Now, trace the dotted lines correctly:
-
Snowman →
Melting
-
Kettle →
Evaporation
-
Freezer →
Freezing
-
Bottle with droplets →
Condensation
---
✔ Final Answer:
- 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 (drops) when cooled.
This helps children understand how matter changes form based on temperature.
