scalpel or a razor blade. Be very careful. Ask for adult
help.

center section of the slide. Add one drop of water. Or, if

IMPORTANT NOTICE: Wash your hands before and after every project.

equipment that you may have used. Be very careful when handling the

How to Use the Camera Adapter
The camera adapter can hold a personal still video camera or a single-
use camera loaded with ISO400-type film. To position the adapter,
remove the microscope eyepiece and place the camera adapter over the
focusing tube. Place the camera on the camera adapter baseplate so
that the camera lens is directly over the hole in the baseplate. Then
place the U-shaped camera holder over the camera and push it down
until the camera is held tightly.
If your camera has a video display screen you can preview the image for
positioning and focus sharpness. If your camera does not have this
screen you may have to experiment with different focus positions and
checking the results. Depending on the camera design you may not need
to make any adjustment. Take your first pictures with the objective lens
almost touching the glass slide. Measure the position of the focusing
tube carefully and keep records of each picture-taking focus position.
When you find the best position that gives a sharp picture you may want
to make a small mark on the focusing tube so that the microscope can
be set at the same position for the next pictures you take. Your best
results will be at the 300X setting.
