A student proposed and followed this procedure to
prepare a cheek smear to view under a microscope:
1. Using a clean toothpick, gently scrape the insie of
your cheek.
2. Wipe the toothipick in the center of a slide.
3. To make a thin layer, hold the coverslip with one
end against the slide and gently wipe the edge of the
cover slip along the middle of the slide's surface.
4. Let the smear air dry.
5. Add a drop of stain to the center of the smear.
6. Gently set a coverslip over the smear.
The diagram below shows what the student saw when
she viewed the slide under a microscope. The shading
shows where the stain stuck to the cheek material.
