Hands up… first to guess gets something tasty 

2. 1- Ocular (eyepiece)
2- Coarse adjustment knob
3- Fine adjustment knob
4- Low power objective lens
5- Arm
6- On/off switch
7- Body tube
8- Revolving nosepiece
9- High power objective lens
10- Medium power objective lens
11- Stage clip
12- Stage
13- Diaphragm
14- Light source
15- Base

3. Functions of Microscope Parts
Eyepiece: Magnifies objects; allows you to view objects
Coarse focus knob: Focuses objects on low or medium power
Fine focus knob: Focuses objects on high power

4. Stage: Where microscope slides are placed
Diaphragm: Can be moved to adjust the amount of light
Revolving Nosepiece: Allows you to change the objective lens (low, medium, high power)

5. Magnification… Each objective lens has its own MAGNIFICATION POWER.
Low power = 4x magnified
Medium power = 10x magnified
High power = 40x magnified
You can multiply this value by the eyepiece magnification to calculate the TOTAL magnification for each lens. The Eyepiece = 10x magnified

6. Calculate the TOTAL magnification for the following:
Low Power Objective Lens = 40x magnification
Medium Power Objective Lens =100x magnification
High Power Objective Lens = 400x magnification

7. Resolving Power
Ability of a microscope to distinguish two close together images as being separate
