DD loved the Magic School Bus episodes on molecular behavior at that age.
The one that I'm thinking of discusses soap molocules, hydrophobic "dirt" and the process of solute/solvent/solvation of particles via a very correct and cogent discussion (albeit a playful one) of colligative properties.
I'm thinking that there are some similar episodes that discuss changes of state.
ETA: I'm a chemist-- so I have pretty high standards for accuracy even in materials intended for children. MSB is awesome as a springboard for deeper exploration because it is so accurate.
