## Notes

- **Particle Model of Matter**: Explains the behaviour of particles in matter. [Understanding](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36476), [PDF p.1](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/pdf/9862?page=1)
- **Basic Ideas**: All matter is made of small particles that are always moving and have spaces between them. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475), [PDF p.1](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/pdf/9862?page=1)
- **Solids**: Particles are close together and vibrate in place. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)
- **Liquids**: Particles have spaces and can slide past each other. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)
- **Gases**: Particles have large spaces and move in all directions. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)
- **Attractive Forces**: Strongest in solids, weakest in gases, affecting particle arrangement. [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)
- **Physical Properties**: Include state, mass, volume, density, and compressibility. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)
- **Mass**: Amount of matter, measured in grams and kilograms. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)
- **Volume**: Amount of space matter takes up, measured in millilitres and litres. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)
- **Density**: Compares mass to volume; denser objects sink, less dense objects float. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)
- **Compressibility**: Ability of a liquid or gas to reduce in volume under pressure. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479), [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36481)
- **Representing Particles**: Students draw and relate particle arrangement to state of matter. [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36477), [Resource](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/resource/ZK9cRtVnOkS6O4OtO76VEQ)
