Sedimentology class reuses and recycles for grain size charts

Dr. Mo Snyder's sedimentology class made their own grain size charts in lab in September. They sieved the sediment and then using recycled floppy disks and old notebook covers, they glued the various grains to any appropriate card of a convenient size. What could be more appropriate than a 3.5 inch floppy disk labelled "3303 final exams"?

The class members show off their geocrafts!
