Kaeli's Exhibition: Pond Scum

Aristea, along with the rest of the class, attended Kaeli's off-campus Exhibition.

Kaeli’s exhibition was on algae and how its appearance changes with depth.

Kaeli had brought in a spectrograph, which for those of you that don't know, the dictionary definition is:
  1. an apparatus for photographing or otherwise recording spectra.

And for those of you who STILL don't know, a spectrograph is a device that measures and records how much green, blue and red is in whatever substance you're putting into it: in Kaeli's case, water with algae floating in it.

So it’s pretty much a rainbow recorder.

Kaeli took samples of algae from one of the ponds in the Matthaei Botanical Gardens conservatory. Then she made charts based on the colors. She also passed around the samples she took so we could see what the charts were on.

After showing us the technical side of the studying, we were released into the wild of the botanical gardens where we got to wander around and learn about all the wonderful plants. We ended with collection, our group meditation practice, at one of the other ponds.

Overall I really enjoyed it!
