This science worksheet helps students visualize the transitions between solid, liquid, and gas states through diagrams and a practical reading example.

Part One: Fill in the Blanks

The task involves filling in the blanks using the word bank provided. The diagram shows three states of matter (solid, liquid, gas) and the processes that cause transitions between these states. Let's analyze the diagram step by step:

#### Diagram Analysis:
1. Left Column (Solid):
- The image shows a solid (ice cube).
- Adding heat energy to a solid causes it to melt into a liquid.
- Removing heat energy from a liquid causes it to freeze into a solid.

2. Middle Column (Liquid):
- The image shows a liquid.
- Adding heat energy to a liquid causes it to evaporate into a gas.
- Removing heat energy from a gas causes it to condense into a liquid.

3. Right Column (Gas):
- The image shows a gas.
- Removing heat energy from a gas causes it to condense into a liquid.
- Adding heat energy to a liquid causes it to evaporate into a gas.

#### Word Bank:
- Solid
- Add heat energy
- Freezing
- Evaporation
- Gas
- Remove heat energy
- Melting
- Condensation
- Liquid

#### Filling in the Blanks:
Using the analysis above, we can fill in the blanks as follows:

1. Left Column (Solid):
- Top: Solid
- Middle: Melting (Add heat energy)
- Bottom: Freezing (Remove heat energy)

2. Middle Column (Liquid):
- Top: Liquid
- Middle: Evaporation (Add heat energy)
- Bottom: Condensation (Remove heat energy)

3. Right Column (Gas):
- Top: Gas
- Middle: Condensation (Remove heat energy)
- Bottom: Evaporation (Add heat energy)

#### Final Answer for Part One:
```
Solid → Melting → Liquid
Liquid → Evaporation → Gas
Gas → Condensation → Liquid
Liquid → Freezing → Solid
```

Part Two: Phase Change Read, Discuss, Respond

#### Passage Analysis:
The passage describes a scenario where Ms. Staal makes a glass of lemonade with ice cubes and places it outside on a hot day. After a few minutes, she notices water droplets on the outside of the glass. This is a classic example of condensation.

#### Explanation:
1. State of Matter 1: The air around the glass contains water vapor (gas).
2. State of Matter 2: When the cold glass comes into contact with the warm, humid air, the water vapor in the air loses heat energy and changes into liquid water droplets on the surface of the glass.
3. Phase Change: This process is called condensation, where a gas changes into a liquid.

#### Drawing Particles:
- Before (State of Matter 1): Draw water vapor molecules as small, fast-moving particles representing a gas.
- After (State of Matter 2): Draw water molecules as closely packed, slower-moving particles representing a liquid.

#### Final Answer for Part Two:
```
Name of Phase Change: Condensation
State of Matter 1: Gas
State of Matter 2: Liquid
Description of what occurred: Water vapor in the air lost heat energy when it came into contact with the cold glass, causing it to change into liquid water droplets on the surface of the glass.

Final Answer:

Part One:
```
Solid → Melting → Liquid
Liquid → Evaporation → Gas
Gas → Condensation → Liquid
Liquid → Freezing → Solid
```

Part Two:
```
Name of Phase Change: Condensation
State of Matter 1: Gas
State of Matter 2: Liquid
Description of what occurred: Water vapor in the air lost heat energy when it came into contact with the cold glass, causing it to change into liquid water droplets on the surface of the glass.
```

Boxed Final Answer:
\boxed{
\text{Part One: Solid → Melting → Liquid, Liquid → Evaporation → Gas, Gas → Condensation → Liquid, Liquid → Freezing → Solid}
}
\boxed{
\text{Part Two: Condensation, Gas → Liquid, Water vapor lost heat energy and changed into liquid water droplets on the glass.}
}
