Change in matter activity - Free Printable

Let's solve the worksheet step by step.

1. Complete the diagram by labelling the changes in matter

We have two pairs of images showing changes between states of water (solid, liquid, gas).

#### First Pair: Ice → Water and Water → Ice
- Ice to Water: This is melting (solid → liquid)
- Water to Ice: This is freezing (liquid → solid)

So:
- Arrow from Ice → Water: Melting
- Arrow from Water → Ice: Freezing

#### Second Pair: Ice on pond → Water in pond and Water in pond → Ice on pond
- Ice on pond → Water in pond: This means ice is turning into water — melting
- Water in pond → Ice on pond: Water turning into ice — freezing

So:
- Arrow from Ice on pond → Water in pond: Melting
- Arrow from Water in pond → Ice on pond: Freezing

✔ So the labels are:

```
Ice → Melting → Water
← Freezing ←

Ice on pond → Melting → Water in pond
← Freezing ←
```

2. Drag and drop the words under the correct pictures

We are given three terms:
- Freezing
- Melting
- Boiling

Now match each image:

#### a) Steam from kettle
- The kettle is producing steam (water vapor), which means water is turning into gas.
- This process is boiling.
- ✔ Label: Boiling

#### b) Falling water turned ice
- Water falling and freezing into icicles — liquid → solid.
- This is freezing.
- ✔ Label: Freezing

#### c) Butter heated in a pan
- Butter (solid) melts when heated → becomes liquid.
- This is melting.
- ✔ Label: Melting

✔ Final Answers:

#### 1. Diagram Labels:
- Top arrow (Ice → Water): Melting
- Bottom arrow (Water → Ice): Freezing
- Second top arrow (Ice on pond → Water in pond): Melting
- Second bottom arrow (Water in pond → Ice on pond): Freezing

#### 2. Matching:
- Steam from kettle → Boiling
- Falling water turned ice → Freezing
- Butter heated in a pan → Melting

📌 Summary Explanation:

- Melting: Solid → Liquid (e.g., ice → water, butter → liquid)
- Freezing: Liquid → Solid (e.g., water → ice)
- Boiling: Liquid → Gas (e.g., water → steam)

These are physical changes in matter due to temperature changes.
