I work in the school system. The glue sticks dry out. How do I soften the glue, so they can be utilized and not thrown out?

Simple solution: take some dried-out glue sticks, with the caps off. Put the tubes with the caps in a zip-lock plastic bag. Add some water. (Some believe simply putting wet paper towels in the bag is better. I believe an ounce or two of water works better.) Let them sit overnight in the bag. The next day, try the glue sticks to see if they've revived.
