EXERCISE 3 – MICROSCOPE OBJECTIVES 1. To identify the parts of the microscope and list the function of each. 2. To demonstrate proper techniques for care and operation of the microscope. 3. To define total magnification and resolution. 4. To demonstrate proper focusing technique. 5. To define parfocal, field, and depth of field . 6. To estimate the size of objects in a field. ACTIVITY 1: IDENTIFYING THE PARTS OF A MICROSCOPE Identify parts of the microscope as well as their functions Features of microscopes (e.g. working distance, resolution, magnification, etc.) Use of the microscope Determination of total magnification, depending on objective lens How to care for the microscope ACTIVITY 2: VIEWING OBJECTS THROUGH THE MICROSCOPE Describe how objects look in the field of vision and in what direction to move them.
