# The Particle Model of Matter: Matching Game

All matter, from your desk to the air you breathe, is made of tiny particles that are always moving and have spaces between them ([PDF p.1](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/pdf/9862?page=1), [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)). In this game you will match key words like particle, vibrate, solid, density, volume, compress, arrange, and movement to their meanings. Matching these terms will help you explain how particles behave in solids, liquids, and gases, and how their movement and arrangement shape properties like density and compressibility ([Understanding](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36480), [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)).

## How to play

1. Look at the word list and the meanings list.
2. Draw a line, or write a letter and number pair, to match each word to its correct meaning.
3. Each word has exactly one correct match.
4. Use what you know about particles in solids, liquids, and gases to help you decide ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475), [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36477)).
5. Check your work with the answer key only after you finish.

## Match the pairs

| Column A | | Column B |
|:---|:---:|:---|
| **A.** particle | ____ | **1.** Mass per unit of volume |
| **B.** vibrate | ____ | **2.** Particles in motion |
| **C.** solid | ____ | **3.** Small unit of matter |
| **D.** density | ____ | **4.** Firm matter with fixed shape |
| **E.** volume | ____ | **5.** Order or placement of particles |
| **F.** compress | ____ | **6.** To squeeze into a smaller space |
| **G.** arrange | ____ | **7.** Space occupied by matter |
| **H.** movement | ____ | **8.** Rapid movement in place |

## Answer key

- **A** matches **3** (particle: Small unit of matter)
- **B** matches **8** (vibrate: Rapid movement in place)
- **C** matches **4** (solid: Firm matter with fixed shape)
- **D** matches **1** (density: Mass per unit of volume)
- **E** matches **7** (volume: Space occupied by matter)
- **F** matches **6** (compress: To squeeze into a smaller space)
- **G** matches **5** (arrange: Order or placement of particles)
- **H** matches **2** (movement: Particles in motion)
