Microscope labs

  1. Describe the proper use of a microscope.
  2. Know the parts and functions of the two types of microscopes encountered.
  3. Apply the knowledge, principals, and techniques encountered in the microscope lab to

new situations.

  1. Be prepared to convert from one metric unit to another.

  3. Given the diameter of the field of view for an objective lens, be able to compute the field

of view for the other objective lenses on the same scope.

  1. Determine the Total Magnification when using different objectives.
  2. Field Size and Magnification: What happens to the size of the field of view as

magnification is increased?, decreased? What are the consequences of this when

viewing specimens under the microscope?

  1. What is resolution?
  2. What two weird visual things happen to the IMAGE of the letter e when you view it under

the microscope compared to when you view it in its normal setting with your eye?

  1. Be able to estimate the dimensions (width, length, diameter, etc.) of an object viewed

under the microscope using mm and/or um.

  1. Predict the order that different layers of an object would come into focus based upon how
