Chemistry/Electrical question.

I'm supposed to design a lab procedure for my Chemistry class, and I want to test the conductivity of two specimens.

The specimens in question are diamond, and graphite.

I know that graphite is conductive, and diamond is not.

How can I use a volt meter to measure the conductivity of the two specimens?
 
If you have a voltmeter, chances are it has an ohm-meter option. Switch it to that, measure it, take the inverse to get conductivity and you're done. If your voltmeter really can only measure voltage and has no other option, then you need to force a current into it. Then use conductivity = I/V
