ecoflask
... observe. The observations were done once a week for almost one-month under a microscope magnifying the organisms to forty times their size. What we were watching for were different types of organisms and if they were there throughout all the observations, if so, did they stay in the same place or were they moving around. We were also to pay attention to the size and numbers of each organism, if they were getting bigger or staying the same, multiplying or dying. The first day of observation I looked before I added anything manually into my ecoflask, I didn’t see much movement, so I went ahead and supplemented my ecoflask. All together I had nine different organisms. Out of the nine, there was two that I never saw throughout the weeks that checked, Paramecium and Euglena, but I knew they had to once be in there since I added those two myself. My best guess was that they died right away within a couple of hours. There is an attached table that shows all my data over a certain time period. I put together my ecoflask on February 19th and checked it weekly until March 5th. The most interesting organisms I thought were the Cyclops, Stentor, and Diffugia. The Diffugia I only saw the first day, but it reminded my of a little motorized toy. It swam around with a back end that was constantly spinning, it was quite amusing to watch it. It appeared to me once that it was seating the algae, whatever it was doing was fascinating to watch. The Stentors were really neat looking, they looked like a bunch of hollow tubes all congregating together, with their wider ends stuck into the algae and the narrow end swaying around. The first day I observed I did not see any of them, then a week later they were all over. Cyclops was probably one of my favorites to watch mostly because it was so huge, I could even see it with the naked eye, which was amazing that I had something that big growing in my little ecoflask. The first day I just saw one zoom by under the microscope, then the next week I saw two, and then the final week, both of them appeared so much bigger. The cause of death to some of the organisms was most likely lack proper nutrients to ob...
