## Notes

- **Particle Model of Matter**: Explains the behaviour of particles that make up all matter. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36473), [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), [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)
- **Liquids**: Particles have spaces between them and can slide past each other. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475), [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)
- **Gases**: Particles have large spaces and move constantly in all directions. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475), [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)
- **Attractive Forces**: Strongest in solids, weakest in gases; heating weakens them, cooling strengthens them. [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), [PDF p.6](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/pdf/10120?page=6)
- **Physical Properties**: Includes state, mass, volume, density, and compressibility. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479), [Understanding](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36480)
- **Mass**: Amount of matter in an object, measured in grams and kilograms. [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)
- **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), [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36481)
- **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), [PDF p.6](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/pdf/10120?page=6)
- **Compressibility**: Ability of liquids and gases to shrink in volume under pressure; gases compress more easily. [Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479), [PDF p.6](https://goa-cc-uat-aili-app-001.azurewebsites.net/library/pdf/10120?page=6)
- **Measuring Tools**: Balance scales and volume instruments used with SI units to measure mass and volume. [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36481)
- **Representing Particles**: Students draw and describe particle arrangements for solids, liquids, and gases. [Skills](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36477), [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/qEoa1QPWPEGVUki1w4Q1Fw)
- **Guiding Question**: How can states of matter and other physical properties be explained by using the particle model of matter? [Guiding question](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36472)
