My own personal favorite is to use a dissecting microscope to inspect  
samples.  Whether video or just the hardware.  The reason I advocate  
a dissecting scope is for the low power - to be able to see things  
that are just hinted at in our normal vision.

I was involved in the development of an exhibit on Pompeii last year,  
so I would definitely include volcanos in your oeurve - there are two  
things that never go out of style for kids - volcanos and  
dinosaurs....Its fairly easy to make an interesting and reliable  
device to show the vibrations when one jumps up and down near it.

Stratigraphy - we did a 12 foot high 'section' through Pompeii.   
Pretty fun, pretty easy, and pretty impressive....to show the strata  
and how the ejecta changed over time.  would obviously have relavance  
to mining (stratigraphy, that is...)
