This is an magnified image of a green organism. It was next to a large piece of algae, so it might be algae.
The sample was acquired last Wednesday, from Baxter Pond.
It was obtained by the recitation section TAs, who took some water from the pond.
From the Foldscope website, they have 140x magnification. This organism was large enough to appear on the slide as a dark speck, about half a millimeter long.
