 In this video we can see two large masses moving next to each other that are two different organisms of the same species.


 This sample was gathered at 6:20 pm from the upper level of Caltech’s turtle pond, by pipetting a small amount of water into a flask.


 Size of the microorganisms:


 Magnification of foldscope: 140x


 Thus, these organisms appear to be around 10 micrometers by 60 micrometers.


 Some questions I have about my video:


 What is the name of these types of organisms?


 How long is their typical lifespan?


 What do they eat?
 


 Why do they appear brown-ish in color compared to the surrounding plant life?


 To answer these questions, I could look up the types of microorganisms that are typically in ponds, and classify what I found. After knowing what they’d are, it is easy to just google them and see the information that results.

 This is flour. The individual grains of flour are much smaller than that of salt or pepper. We can feel this difference, as flour’s softer and smoother texture is due to the smaller individual pieces.

 This is the cross section view of an orange leaf. We can see some cells lining the walls of the leaf. The somewhat thicker layer on the right is the top of the leaf, as it needs more protection on top as well as the fact chloroplasts are much more concentrated on top of the leaf.

 This sample was gathered at 5:03 pm on 5/12/19 from my mascara that I use. I gathered the sample by just using the wand, already covered in mascara, and wiping a little on the slide then smooshing it down a little with the coverslip.
