The sample shows possible material from the turtle pond at Caltech. The sample was obtained on 4/8 around 7:45 PM by a TA who collected the sample from the turtle pond. The sample was obtained by collecting the water in a small plastic vial.


 I wonder what kinds of organisms are being shown under the microscope, and what size they are without the magnification of the foldscope.

Bi 001 Turtle Pond Sample

Description: These images are of hibiscus pollen from the flowers next to page. The first image shows the pollen, and the second/third images show where I got it. The image of the pollen shows individual pollen grains through the lens of the foldscope. There is clear separation between the grains in the image.

 Location and Time: Collect 5/3 at 2:09PM, at the flower bushes next to Page.

 How the sample was obtained: The sample was obtained by removing some of the pollen from the middle of the flower. Tweezers were used to pick the pollen off the flowers onto a paper sheet.

 Some questions I have about my image are why there seem to be darker small rings within each round pollen grain. I also wondered why the edges of the image were more out of focus, and what I could do to minimize edge blur. To determine what these darker rings are, I could do more research on the anatomy of flower pollen or ask an online forum.
