In this image, we can see an image of what is supposed to be algae from the turtle pond. The black spots were the parts that were actually swimming around when I looked through the foldscope. This sample was obtained from the turtle pond on April 18th, 2019 at approximately 4pm with a plastic cup from Chandler Cafe. The cup was lowered into the pond and used to collect water with algae. The algae water was placed on a slide for later viewing.

Questions about my picture: In this specific picture, which was the only picture that worked on my phone, I notice that I can’t clearly identify algae. Why is this?

My answer to my question: Looking back, increasing magnification on the foldscope would’ve helped make the picture clearer.
