Practice
A microscope is a scientific instrument. Think of it like a musical instrument: practice, practice, practice.

Focus
The focus wheel adjusts your lens. Examine a penny. Look for Lincoln. Move the lens in and out. Suggestion: keep zoom at 60x.

Location
Notice that the microscope turns the letter “e” upside down and backwards. Learn to search in reverse directions.

Power
Microscopes move images closer to your eye. How much?
that depends on light and lens quality. Compare a ruler at
60x(sixty power) then at 100x (hundred power).

Depth of field
Microscopes focus on surfaces. Notice that you will have to refocus to clearly see the surface in stacked paper.
