How to prepare the sample and use the microscope

Place the filter paper on a petri dish or small flat plate, and then place under the microscope.

It will take a bit of trial and error to adjust the microscope to give you the best image.  There is no need to go the maximum magnification, around 10x or 20x times is more than sufficient.
