Teaching Resources
Main Topics
- Friction
- Thermodynamics
- Heat
Sample Learning Goals
- Describe a model for friction a molecular level.
- Describe matter in terms of molecular motion. The description should include: diagrams to support the description, how the particle mass and temperature affect the image, what are the differences and similarities between solid, liquid and gas particle motion; how the size and speed of gas molecules relate to everyday objects.
