Build a Micrograph

Add an extra dimension to that old microscope of yours. Expand the view from the eye piece so a group can enjoy the view!


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 MICROGRAPH

With 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.
