10/12/2011

today we created our micro aquariums for biology lab.  we began by gathering the materials for our tanks which included the container, a base, and a lid.  we then filled the aquarium with water from one of 12 sources from around the knoxville area.  i chose number 10 to use in my aquarium which was water taken from a pool below a spring at Lynnhurst cemetery.  To ensure that all forms of miroorganisms were added to our tanks, we extracted water from the top and middle of the water profile, as well as sediment from the very bottom of the sample.  once the water and sediments were added, we then placed two types of aquatic vegetation to the tank.  one of the plants was named Amblestegium sp., a moss taken from a spring at Carters Mill Park.  the other was Utricularia gibba L. which is a carnivorous plant grown in the greenhouses outside the hesler biology building on campus.  after everything was added to the aquarium we were able to inspect the contents for signs of life using the microscopes. 

upon initial investigation, any definitive evidence for the presence of  microorganisms was not observed.  A few very tiny organisms appeared to be swimming in the water, but I was unable to focus on any one organism long enough for a thorough analysis of its structure.  I am hoping more will appear in the time to come.
