The document describes two methods for building a simple micrograph to view microscope images. The quick and easy version uses an upside down flask with a piece of frosted plastic or tracing paper held in place with a rubber band as the viewing screen. The alternative method requires constructing a wooden box with a hole cut in the bottom to fit over the microscope and another hole in the top covered with frosted glass as the viewing screen. Both allow focusing the image and tracing observations on paper.

018 build a micrograph
- 1. 018 BUILD A MICROGRAPH 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.

- 4. 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 dark room
