Gray rock quiz
Several years ago, (former) NOVA student Theresa R. put together a nice little webpage with rock and mineral photos. My favorite part is a "gray rock quiz" at the end. Check it out and see how well you do!

A very interesting quiz! At first I thought maybe I should just guess greywacke for everything. It's funny when the clues say, "you're holding a chunk of gray rock." I slowly got them all right, then was able to figure out the first one, which I had skipped over!
Very nice webpage they put together.
