 Another test we can perform has to do with magnets. When I take a particular sample and I move it near a magnet, is it attracted to the magnet? Or if I take that sample and place it near the iron filings, are the iron filings attracted to the sample? And obviously for calcite, they aren't. But let's go ahead and do that test for all of the other samples. The mica, the quartz, the sulfur, the magnetite, pyrite, and our unknown sample. Again, write down your observations about whether the sample was attracted to the magnet and if the iron filings were attracted to it.
