When I taught 7th grade science, one of the first things we would do in class would be to look at pond water under a microscope. The kids were always mesmerized by all of the living stuff in a single drop of water.
These are awesome pics, too! What kind of equipment did you use?
I'm not exactly sure since I wasn't using my own equipment. I am pretty sure it was a cam from bresser though. And a very fancy olympus microscope. I was there mainly to make pictures with the SEM.
