Learning Outcomes:

1. show an awareness of the particulate nature of matter being a model representing matter made up of small discrete particles in constant and random motion

Using models,

2. describe the arrangement and movement of the particles in matter in the solid, liquid and gaseous states

3. show an understanding that diffusion is the net movement of particles from a region of higher concentration to a region of lower concentration 

4. explain expansion and contraction, and the conservation of mass during these processes

5. explain melting and boiling in terms of conversion of the three states of matter

6. explain, using the heating or cooling curve, what happens to matter at different temperatures

7. show an appreciation of scientific attitudes such as creativity and open-mindedness in creating models to explain the fundamental nature of things and the willingness to re-examine existing models e.g Brownian Motion
