The Particle Nature of Matter: Solids, Liquids, and Gases
What explanation might account for the differences between the states of matter, as well as explain its different properties? Session 2 introduces the particle model of matter, the principles which underlie a wide range of phenomena. By contrasting this model with what is variously called the continuous, continuum, or plenum model, this session shows how the particle model is

Rising and Sinking
Why does a hot air balloon rise into the sky? Why does ice rise in water when a lump of solid wax will sink in a jar full of melted wax? In this session, we’ll generalize the model we’ve developed about what rises and what sinks, using the idea of balance of forces.
