This is a video of a sample from the lily pond outside of Baxter as seen through a foldscope microscope. in the sample you will see little specs of what I think is bacteria. There are many specs of different sizes – some are larger and some are smaller. It was difficult to take a picture so I took a video instead.


 The domain is bacteria because I do not see a nucleus.

Lily Pond Sample

 This is a sample of pollen collected from a yellow lily by the turtle pond on the Caltech campus. The sample was collected today (5/10/19) at about 3:30 pm (#procrastination) by plucking off one of the stems that held the pollen. We see that the pollen is green in color (probably due to the light) and shaped like almonds. The image also features some clear colored spots which are probably just air bubbles in the slides.

Nectar from flower (purple acacia)


 Ricketts courtyard, 2:30 pm


 In this image we see some cells from the nectar of this purple flower. The cells are spread out and were moving throuhgout the photo.

Onion skin


 Ricketts courtyard, 2:40 pm


 These images show the cells from the skin of an onion. You can see that there is a lot of water in these cells.

Lettuce, ricktts courtyard, 2:50 pm


 In the cells of the lettuce leave we see a lot of green (chloroplasts!!!). The image is zoomed in on one of the veins, which is the lighter green on the picture.

apple skin, ricketts courtyard, 3 pm


 in these images we see that the pictures are “grainy” but that is actually jsut how the cells are aranged. we also can see that there is a lot of water in teh cells

dead skin from my hand lol, 3 pm ish


 This image was harder to focus on so it is a little blurry. here we see a little bit of the structure of the cells of the skin – it is interesting to discover how this arrangement turns into skin!

purple flower petal


 These cells were definitely more structured than other pictures. In this image you see a lot of purple veins which contributes to the color of petal.

this is my hair!


 this was hard to align since my hair is so thin. you can’t see indiviudal cells in this but it is still cool to see the alignment of the strands all together. they are very linear which makes sense since my hair is so straight.

skin from a cherry tomato!


 in this image the cells are
 
 very
 
 defined – all of the cells have a clear pentagonal or hexagonal structure. it’s interesting to note that the picture is also yellow, this is probably from the chloroplasts

radish skin!


 this was fun to look at because it is pink! i guess this image is of teh intersection of teh white and pink skin which is cool to look at under the microscope. again you can see that there is a lot of water in tehse cells.
