Sand Collection Archive


  1. Hi,
    Thank you for sharing the wonderful photos of your sand collection. I am going to show these photos to my first graders as part of our rock studies. Can you please tell me about the magnification used while photographing the sand? Are 287, 288 and 289 single grain photos?

    • Hi Kathleen. Yes, 287 – 289 are single grain photos. The magnification varies for each of the photomicrographs, but it is displayed in each at the top center of the photo. At the bottom left is a scale bar. Thanks for your comment!
