First day microaquariam set up

When we got to our lab, we all grabbed a small container that would hold our microaquariam. Professor Mcfarland explained to us the various water samples he collected then we got to choose which water source we wanted to use. We set up this aquariam by putting togeather a small glass with a lid and a bottom stand. I chose to use a water sample from a duck pond. We filled the water about half way to the top then added plants to the water so that they can keep alive what ever organisms we had in the water. I decided to use all three plants. The organisms i saw under the microscope were mites. They looked like minature crabs and stayed in the dirt at the bottom of my microaquariam. That was the only living organism I could find under the microscope.
