 This image is a magnification of water from Millikan pond. It was obtained midday on 4/9/19. The water sample was obtained by filling a plastic cup of water with pond water (dragging it across the pond surface). The domain of the spiky organism in the center, right of the image is likely Bacteria. I believe this because it seems to resemble the shape of a coccus virus bacteria. Eukarya, for example, on the other hand, would likely appear more complex (have more organelles, while the microorganism in the sample looks quite simple). The foldscope has a magnification of 140x and the bacteria could be roughly 1 micrometer.
 
 1) I wonder whether the microorganism is truly a bacteria/archaea/life-form or just some type of debris. We could try Gram staining the sample or culturing the bacteria to see what kind of bacteria it is/whether it really is a living microorganism.
 
 2) I also wonder how much of the integrity of the sample is maintained under magnification with the foldscope because I found that my foldscope’s lens itself had particles on it (without the sample present) that I was unable to clean. Here, we could use a different foldscope or lens to view the sample and verify which parts of the image are truly part of the sample and which are not.
 
 Apart from the spiky organism observed above, much of the rest of the image seems to be just water or debris.

Pollen from front of Caltech&#8217;s campus

This dandelion was plucked from mid-stem at 8:00 pm in front of Ruddock House. It was solo (no other dandelions were near it). In the image, we see part of a dandelion seed!

A leaf from a small fern plant on Hill Avenue was plucked at 7:57 pm. The foldscope image shows part of the fern leaf and the creases along the leaf.

A strand of hair was plucked from my head at 11 pm in Ruddock House. The foldscope image shows the magnification of the single hair stand, which is brown in color.

My hair!

A red rose petal was plucked from a rose bush along Hill Avenue at 7:47 pm. The foldscope image shows a magnified portion of the petal, which seems largely uniform and relatively opaque.

A stamen from a Hibiscus flower on Hill Avenue was plucked at 7:50 pm. The foldscope image shows a portion of the stamen that likely has some pollen sticking to it.

Hibiscus Flower!

A small yellow flower from a weed was plucked from a grass patch on Hill Avenue at 7:52 pm. The foldscope image shows the interface between 2 petals of the small yellow flower. We see a very small, fine gradient of yellow to green coloration in the petals and the roughly ovular shape of the petals.

Small Yellow Flower!

Around 8:04 pm, a bigger fern plant than from before was found along Hill Avenue. A string of small leaves was plucked from the plant. The foldscope image shows the magnification of a small leaflet from the fern, which we see is largely opaque with a few white dottings.
