  0:17 – 0:21 is the notable part where we see motion of some microorganism. It darts in from the top right-hand side and exits back through the middle of the top of the frame. This is a sample of water from the Caltech Turtle Pond gathered on 04/10/2019 at roughly 6:00 pm. The water was collected by TAs shortly prior to recitation section. From the current resolution, we cannot conclude anything significant regarding the domain of the microorganism which we saw moving. To improve in the future, we will need to find a phone which does not vibrate as much upon proximity to a magnet. #caltechbi1

 Sample of pollen was collected from the Avery inner courtyard on Tuesday May 28 around 2 pm. The pollen was obtained by taking out the stamen from the center of the flower and gently tapping it against the glass slide. We stopped once we had about a square of pollen with length and width roughly half the width of the glass slide. We note that the pollen, as viewed underneath the Foldscope, are each individually oval-shaped. #caltechbi1

 The sample was obtained at roughly 2:05 pm on Tuesday May 28, 2019 at Caltech. The stamen was obtained by peeling back the flower petals and obtaining the stamen inside. We simply placed two of them underneath the cover slip and viewed it under the Foldscope. As for the Foldscope picture, we see the varying gradient of color as the center of the stamen appears to be more clear than the edges. #caltechbi1

 The sample was obtained around 2:15 pm in the Avery outer courtyard beyond the gates on Tuesday May 28, 2019. We simply taped down the sample as it was on the larger side, so falling off the slide was an issue. Underneath the Foldscope, we can see the minor wear and tear along the edge of the spike as well as gashes on the flat end of it. A potential suspect for the cause of this would be insects. #caltechbi1
