 This is a photo of an organism found in a sample from the turtle pond. It was taken in Bio rec at 8:50 pm on 4/09/19. This photo was taken using an iPhone and a foldscope held up to the light.


 One question I have about the image is the sparseness of the organisms seen, despite the clearly populated water source. I believe this could be due to an unclean slide or dirt on the lens itself, despite efforts to clean using the provided q-tip. These layers of would obscure smaller organisms, since the lens is not very strong. It is also possible that the method used to put the cover slide on pushed most organism out from underneath, resulting in a minimally populated sample.

 This image shows small pollen molecules collected from an orange hibiscus flower. It is easy to see the surrounding wall around the cellulose, and in a few you can make out the nuclei of the cells they are made of. This sample was taken on May 5th, 2019 at 4:00 pm, from a hibiscus plant on the Caltech campus, outside Page house. To collect the sample, a slide was held underneath the anthers, which were gently tapped until a few pollen grains fell onto the slide. These were covered with a slide cover which was then taped down. It would be interesting to see if different species of hibiscus have significantly different pollen grains. This could be answered by collecting samples from several different species and comparing their physical structures under a foldscope.
