Beach sand is the most beautiful thing to look at under a stereo microscope. The sparkling beach sand are formed by the erosion and weathering of rocks by tidal waves and winds. The rocks eroded by streams and rivers might be carried and settled in the beach. Aside from the elements from the rocks of the inland, the beach sand might also contains the deposits of the marine lives, such as coral and sea shells. Polished by the tidal waves, they are just pretty to look at.
I found a thin layer of sand settled on the bottom of the bucket which we used to collect sea shells on the trip to Clearwater Beach last summer. I just learned a simple method to collect sand specimens using a piece of paper and adhesive tape. I was able to recover some from the bucket and put it under the microscope for observation.
The Beach Sand Collected from the Florida Beach Contains many different types of Sands. The harder materials seems to maintain their shapes. The softer sands seems to be more rounded.
The specimen is either observed at 20X or 40X using Ample Scientific SM-Plus-13 stereo microscope. The pictures were taken with Tucsen 3.0 MP CMOS microscope camera.
