THE QUICK AND EASY VERSION....The simplest micrograph uses a 250mL conical flask, upside down, and resting over the eyepiece. A piece of frosted (translucent) plastic or tracing paper covers the "bottom" of the flask and is held in place by a rubber band. This forms a viewing screen. THE ALTERNATIVE...The other type requires the construction of a light weight wooden box mounted on legs. A hole is cut in the bottom of the box so that the box will fit over the eye piece of the microscope. A hole is cut in the top of the box and a piece of frosted glass is used to cover the hole. This becomes the viewing screen.
USING A MICROGRAPHWith either type, the image can be focused by turning the focusing knob on the microscope. For a permanent record of your observations, place a sheet of tracing paper over the viewing screen. You should be able to see the object through the paper and trace it. For best results, use the micrograph in a darkened room. Things you could make drawings of include legs of various insects like a bee, fly or grasshopper. What about the mouth parts or eyes? Perhaps you could make a work of art using water colours, charcoal, or crayon. FIND OUT MORE:-
