Judy,

I use (and perhaps you did as well) the rotating mirror system employed by
Robert Millikan.  If it takes a period of time for one of the
mirrors to move, say 1/8 of a total revolution, and the distance light
travels for that time interval is known, then one can show how c is
calculated.  It is much easier to explain than it is to do but the rotating
mirror explanation seems to work quite well.

Are you after specific quantitative information such as, how many times
did Millikan bounce the light beams back and forth?
