Parts of the Scope
S Eye piece ----------------------
S Objectives---------------------S Neck ---------------------------S Stage---------------------------
S Light----------------------------
Magnification
S Eye piece power of X10
S Objectives Red power of 4
Yellow power of 10
Blue power of 40
Total power = eye piece x objective
Focus
S Course – large inside knob
- to be used first
- start with stage low
and bring up
S Fine – small outside knob
- makes picture crisp
- Clear image
Field of view
S Small white circle that can be seen inside the microscope.
S Two ways to change the field of view
Moving the stage
Adjusting the focus knob
Where are cells involved
in life processes?

Use pencil
Only draw a few cells –
NOT everything you see.
Draw larger than what you
see!
Add details
Label parts you identify
Take your time!
