The Conduction of Heat

Eureka! Episode 22 - Atoms
This program explains that molecules are made up of atoms. In pure metals, all the atoms are arranged separately in a lattice-work pattern, but in most non-metals, liquids, and gases, the atoms are bunched together into molecules. Eureka! Episode 23 - Electrons
Using an animated model of an atom, Eureka! illustrates how electrons whiz so quickly round the nucleus that they appear to form layers Eureka! Episode 24 - Conduction
Eureka! looks at the process of conduction, explaining that the application of heat to an object makes the molecules or atoms vibrate faster and cause a sort of "domino effect.
