Microscope 101: Ponds, Webs & Microbes

Grace found the new microscope and prepared slides a week ago, so I promised her that since we didn't have any "school" on the weekend, we could break out the microscope. Today, Grace and I sat down and reviewed some prepared slides to start: insect legs, earthworm cross-section, etc. And then we sought out our fish pond water and some other items to prepare a few slides. This was a blast!

Our first pond water sample was a little weak on life, with only a few paramecium and suckers whizzing by way too fast to identify. Our second sample of pond water had a water mite swimming around that we were able to catch and place on a slide. Here he is:


Next we took a sample of a spider web over the pond, and we discovered that there is much more to a web than first meets the eye. It looks like a strand of pearls with sticky globules that help the prey stick to the web. We also discovered that our web sample had a tiny leg still stuck to it from a previous meal (not pictured):


Our last water pond sample was the ultimate find. There was life and activity everywhere, of which mom is scrambling to identify. I'm still not positive on the identification of the larvae, but my best guess after some research is this is a mosquito larvae. Below are two pictures: the head and a portion of the body. The body was teaming with paramecium and other microbes. We were also able to record video. (I love this scope!) Below are two pictures:
