What would you use for this experiment? (xpost)

This is for earth science. You are supposed to test a "variety" of materials (not necessarily metals or minerals) for hardness, density, electrical conductivity, flexibility and malleability, magnetic properties, thermal conductivity, and color & luster.

I guess my brain is mushy, I can't think of what to use as samples to tests.
Thanks in advance!
