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.

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
