How do you collect microscope samples?
The main methods of placing samples onto microscope slides are wet mount, dry mount, smear, squash and staining. Dry Mount: The dry mount is the most basic technique: simply position a thinly sliced section on the center of the slide and place a cover slip over the sample.
How do we get microorganisms in water?
Membrane filtration: Membrane-based tests are the most quantitatively accurate. In general, a 100 mL water sample is forced or vacuumed through a small, round filter paper (the membrane) using a little hand pump. All the bacteria in the sample are caught on the filter as the water passes through.
What microscope should you use to view pond water?
Microscope– one that you can observe over 100x. At least 400x is probably best to see the Protists large enough for identification. Digital Microscope Camera– if you want to record video of your microorganisms in action; Pond Source– one where you can easily collect some water (not state or federal parks)
