Parts of the Scope Eye piece ---------------------- Objectives---------------------- Neck ---------------------------- Stage--------------------------- Light---------------------------- Base----------------------------

Magnification Eye piece power of X10 Objectives Red power of 4 Yellow power of 10 Blue power of 40 Total power = eye piece x objective

Focus Course – large inside knob - to be used first - start with stage low and bring up Fine – small outside knob - makes picture crisp - Clear image

Field of view Small white circle that can be seen inside the microscope. Two ways to change the field of view Moving the stage Adjusting the focus knob

Where are cells involved in life processes?

How to draw a GREAT picture! 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!
