Why can't I see any organisms in Biology Experiment 3.1?

If someone has a lot of trouble seeing organisms in this experiment, it is
usually because of lack of patience or improper focus. To cure the lack
of patience one, make sure you stay at LOW POWER while you scan the slide.
Scan it SLOWLY, looking for little dots that move. When you find them,
ONLY THEN should you go to higher magnification. You will spend the vast
majority of the time at low magnification.

To make sure that you are focusing at the proper level, make sure that
some of the food (egg yolk, rice bits, etc.) gets into the dropper and
onto the slide. Then, focus (at LOW MAGNIFICATION) on the food. Once the
food is in focus, don't change the focus. Just scan the slide.
