Equipment: 

JustTemp set & mallet, tuning fork scale sets.

Procedure:

Each set of bars spans two octaves.  One set is a "Just" scale, the other set is a "Tempered" scale. 

Two sets of tuning forks are available.  One is a "Scientific Pitch Notation" scale.  The other is a "Concert Pitch" scale.
