Educational worksheet on phase changes in matter, guiding students to identify and describe transitions between solid, liquid, and gas states using diagrams and real-world examples.

Part One: Fill in the Blanks

The task involves filling in the blanks using the word bank provided. The diagram illustrates the phase changes between solid, liquid, and gas states of matter. 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.

#### Filling in the Blanks:
Using the word bank, we can fill in the blanks as follows:

- Left Column (Solid):
- Top: Solid
- Middle: Melting
- Bottom: Freezing

- Middle Column (Liquid):
- Top: Liquid
- Middle: Evaporation
- Bottom: Condensation

- Right Column (Gas):
- Top: Gas
- Middle: Add heat energy
- Bottom: Remove heat energy

#### Final Answer for Part One:
```
Solid → Melting → Liquid
Liquid → Evaporation → Gas
Gas → Remove heat energy → 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 that her hand is wet when she picks up the glass. This indicates that water has formed on the outside of the glass.

#### Identifying the Phase Change:
1. State of Matter 1: The water vapor in the air (gas) is the starting state.
2. State of Matter 2: The water droplets on the outside of the glass (liquid) are the ending state.
3. Phase Change: The process that converts gas to liquid is called condensation.

#### Description of What Occurred:
When the cold glass comes into contact with the warm, humid air, the water vapor in the air loses heat energy and condenses into liquid water droplets on the surface of the glass. This is why Ms. Staal's hand gets wet when she picks up the glass.

#### 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 and condensed into liquid water droplets on the outside of the cold glass.
```

Final Answers:

Part One:
```
Solid → Melting → Liquid
Liquid → Evaporation → Gas
Gas → Remove heat energy → 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 and condensed into liquid water droplets on the outside of the cold glass.
```

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