 In this image taken with a Foldscope, we can see a wet sample taken at 7:30pm, April 16th, at the turtle pond at Caltech. It was obtained by extracting water from the pond using a pipette and a falcon tube. A drop of it was subsequently placed onto a slide using the pipette. The image is mostly blank except for one dark patch – a stationary, relatively large organism in the top right of the circle.


 The rather distinct appearance of the organism indicates that it is almost certainly algae -perhaps Ulva Algae. One can determine this by examining the image and comparing it to images of algae. Thus the domain of the organism is Eukaryote, as this is the domain that algae belong to.

 The sample above was obtained at approximately 6:30 pm, in the area near the gated entrance to Ruddock House (within ~50ft of the gate). It was prepared by obtaining a flower, and rubbing its onto a slide, which was placed onto the foldscope. It is possible to dark spots, which are pollen, in the resultant image.


 The below sample was also obtained at approximately 6:30 pm, in the area near the gated entrance to Ruddock House. It was prepared by obtaining a leaf, and placing a small piece of it onto a slide which was placed onto the foldscope. One can see an elaborate pattern of intersecting lines and circles – these may be plant cells.
