# The Particle Model of Matter: Word Search

Every solid, liquid, and gas is made of tiny particles that are always moving, with 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 word search, you will look for words that describe how particles behave and how we measure the matter they make up, including MASS, VOLUME, and DENSITY ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)). You will also find words like VIBRATE and ATTRACTIVE, which describe how particles move and pull on each other depending on whether they are packed into a SOLID or spread out with more freedom of MOVEMENT ([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)).

## How to play

- Search across, down, and diagonally to find all 8 hidden words about particles and matter.
- Circle or highlight each word as you find it, then cross it off the word list below.
- When you finish, use what you learned to explain to a partner how particles behave differently in a solid compared to a gas ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36473)).

## Words to find

- ATTRACTIVE
- DENSITY
- MASS
- MOVEMENT
- PARTICLE
- SOLID
- VIBRATE
- VOLUME
