Day 156: Unknown Sand Lab

IMG_4318

Today we (IS II students and I) reviewed the procedures for a multi-day lab where they collect qualitative and quantitative data on 8 unknown sand samples. They describe the samples and determine grain size, settling velocity, roundness, luster, and the terrigenous vs biogenous component. I then give them descriptions and they have to match their samples with the correct locations. This year the sands are from Bermuda, Galapagos Islands, Daytona Beach, Miami, Uruguay, San Diego, Maui, and Costa Rica. There is great detective work and students always enjoy seeing the sand under magnification.
