This is an image of the water sample taken from Turtle Pond at Caltech. The microscopic spots on the image are likely small bacteria (observed them moving) and chunks of pond gunk from the plants. The sample was obtained on 4/8/19 at around 7:45 PM by our TA. The sample was obtained by sticking a tube into the water and collecting the liquid into a small plastic vial. Some of the questions that I have about my image include: 1.) Using the foldscope and perhaps some easy-to-access resources, what are some methods that I can use to see more in my images? 2.) How can I identify what I am seeing in my sample? For 1, one could potentially use difference light sources (UV light, etc) and stains to accent some parts of the organisms. Also, one could use a better camera to capture and focus on what is going on under the lens. For 2, one could potentially go through samples of identified common organisms that live in still water ponds and verify them. This would also be cross referenced with multiple sample images of the pond water to verify that the identified organisms do exist in the pond. #caltechbi1
