Protists in the Campus Pond

Joanna WangBiology 197

Methods• Joanne, Victoria and I went to the campus pond on

Monday to get samples

• We switched roles between taking pictures, recording location/time, and actually going into the pond

• In the pond, we tried our best to getsamples from where the water met

the soil. It was a chilly and duck- filled process!

• In the next few slides, I have included pictures of the locations where we obtained the samples, pictures of the contents of our samples (taken under the microscope), and the possible identity of my protists.

• Admittedly, most of my pictures are just of debris. I did not observe much movement under the microscope. The few times I did, however, I was too slow in changing from microscope lens to camera lens. Next time, I would try adding a slowing agent to get better pictorial results.

• Regardless, I added in the pictures that looked most interesting to me. Enjoy!

Location #2 – Vial #6This piece was actually spinning in circles when I viewed it under the microscope.

However, I was skeptical about whether it actually is a protist or just being influenced by the moving water on my slide
