Additional promotional materials will be distributed at the fall GAC training sessions. Nationally, some 5,000 local recycling and Buy Recycled Events are expected to be held prior to the event.

It helps first to understand the atomic nature of things.
All matter is made of atoms, which are themselves mostly empty space.
Atoms combine to form molecules that in turn combine to form all of the compounds and substances of which matter is composed. The matter's state is, however, determined by HOW it's atoms move. In solids, atoms and molecules vibrate about in fixed positions. In this latticework, each atom vibrates about it's own fixed position and is never quite able to move through the lattice. However, some solid materials have no regular atomic structure.
