Pond scum obtained from the BBB lily pad pond at 6:50 pm on 4/8/19 by stick a falcon tube into the pond. The foldscope has a magnification of 140x, and the organism in the image seems to be approximately 5*10^4 cm long. #caltechbi1

 A sample of pollen collected from outside Beckman Institute at Caltech, viewed through a Foldscope. Mostly small, round looking cells can be seen, although in the lower left corner there are some longer shapes as well. This sample was obtained at 2:04 PM on Friday, May 10th. A flower was plucked from the bushes and peeled open to find the pollen, which was then rubbed off onto the slide.


 The pollen came from a small, white, flower with 5 petals. This is likely from the common jasmine flower (jasminum officinale).


 The magnification of a Foldscope is 140x. The magnified round particles are about 1-2 mm across, and divided by 140 this is .007-.014 mm, so the actual pollen particles are then about 7-15 microns across.
