Problem Analysis:
The task involves understanding the changes in matter, specifically focusing on the states of water (solid, liquid, gas) and the processes that cause these changes. Let's break it down into two parts:
---
Part 1: Labelling the Changes in Matter
The diagram shows different states of water and asks us to label the processes that transform one state into another. The states are:
- Ice
- Water
- Ice on pond
- Water in pond
#### Steps to Solve:
1.
Ice → Water: This is a transition from solid to liquid. The process is called
melting.
2.
Water → Ice: This is a transition from liquid to solid. The process is called
freezing.
3.
Ice on pond → Water in pond: This is also a transition from solid to liquid. The process is called
melting.
4.
Water in pond → Ice on pond: This is a transition from liquid to solid. The process is called
freezing.
#### Final Labels:
- Top arrow (Ice → Water):
Melting
- Bottom arrow (Water → Ice):
Freezing
- Middle left arrow (Ice on pond → Water in pond):
Melting
- Middle right arrow (Water in pond → Ice on pond):
Freezing

Part 2: Drag and Drop Words Under Correct Pictures
The task is to match the words "Freezing," "Melting," and "Boiling" with the correct images. Let's analyze each image:
1.
Steam from kettle: When a kettle boils, it produces steam, which is water vapor. This process is called
boiling.
2.
Falling water turned ice: When water falls and freezes, it turns into ice. This process is called
freezing.
3.
Butter heated in a pan: When butter is heated, it melts from a solid to a liquid. This process is called
melting.
#### Final Matches:
- Steam from kettle:
Boiling
- Falling water turned ice:
Freezing
- Butter heated in a pan:
Melting

Boxed Final Answer:
\[
\boxed{
\text{Melting, Freezing, Melting, Freezing, Boiling, Freezing, Melting}
}
\]
