When we were out in the field, the third years told me they felt they needed more practice identifying rocks in hand sample. Of course I asked myself, "What would Hilde do? She would find a way to give a prize." Thus was born:
Each week I will put a new and different rock out in the office with 3-pts worth of questions and all the students will try to identify the rock and submit their answers. Winners for each class level are named at the end of the semester. Just for fun, I'll post the RoW here on my blog as well and you kids can play along at home. This is the e-RoW. No handlens, knife, or acid on the monitor.
