MaryJ,
If physical organization is an issue, maybe try doing a 5S on one section. For instance, my former team really needed it on the electronics for several years. The mentor who controlled the wiring and electronics had is squirreled in a way that made sense to him only and he had no interest in helping anyone else figure it out.
Pick one area (electronics, motors, raw metal, wrenches) and work with the students to 5S that area. Part of the upside of 5S (
http://en.wikipedia.org/wiki/5S_%28methodology%29) is that there is no longer the excuse of "I can't find it" because everything is mapped, labeled, and illustrated. When properly done, someone who has no idea what you are talking about should be told to get an item and they should be able to find their way to it without much extra assistance (for instance - "Get me a CIM motor, please").
If you PM me your state, I can probably point you to some other resources that may help.
