 Sample of scum from the turtle pond. Sample obtained from BBB Lily Pad pond, 4/8/19 @ 6:50 pm by sticking falcon tube into pond.
</p>
<p>
 Domain: Eukarya. I can see a membrane-bound nucleus. 140x magnification. Organism is about 3 micrometers.
</p>
<p>
 What exactly are the organisms? We can use a better (real) microscope to look at the sample to determine this.

  This is a (pretty low quality) image of a pollen sample from the pink flowers next to Linde on Caltech’s campus. The sample was obtained at 4pm on 5/8/19. The sample was obtained by scraping the insides of the flower to get the dusty stuff (aka pollen). The dark spots in the image are the pollen.

 The foldscope has 140x magnification, and each pollen grain is about 1mm across. Therefore, each pollen grain is ~7 micrometers in diameter.

   Sample was obtained at 5:05 pm by picking a leaf off of the bushes outside Ruddock in the courtyard. This is a microscopic view of part of the top layer of the leaf, which I got by scraping the leaf with an X-Acto knife.

   Sample was obtained at 4:11 pm from the flower picked from the bushes between Linde and Bridge. This is a close-up view of one of the hairs on its stem. You can see the jagged edges of the super-fine hair.

   Sample was obtained at 10:37 am by picking a leaf from the bushes outside of Ruddock’s RLZ entrance. The resolution on this image is not very high because I couldn’t get it into thin layers. However, you can kind of see the veining in the leaf.
