2. the history of MICROSCOPES
MICROSCOPES MAGNIFY SMALL OBJECTS
SIMPLE MICROSCOPES HAVE A SINGLE LENS
FIRST LENSES MADE ABOUT AD
SIMILAR TO A STRONG MAGNIFYING GLASS TODAY
COMPOUND MICROSCOPES HAVE 2 OR MORE LENSES
EYEPIECE: LENS NEAR EYE, MAGNIFIES IMAGE
OBJECTIVE: LENS AT BOTTOM OF BODY TUBE, FORMS AN IMAGE
MAGNIFICATION :RESULTS FROM THE PRODUCT OF THE POWER OF EYEPIECE AND OBJECTIVE
MOST COMMON LIGHT MICROSCOPE USED

3. the history of MICROSCOPES
ELECTRON MICROSCOPES: REFLECTED ELECTRONS FORM IMAGE
ALLOW EXTREMELY HIGH MAGNIFICATION
GIVES EXCEPTIONAL DETAIL
VERY EXPENSIVE
RESOLUTION: SHARPNESS OF IMAGE
DEPENDS LENS QUALITY, ABILITY TO FOCUS
ALLOWS GREATER DETAIL TO BE SEEN CLEARLY
MOST IMPORTANT ATTRIBUTE OF MICROSCOPE

4. the history of MICROSCOPES
ANTON VON LEEUWENHOEK FIRST TO OBSERVE LIVING CELLS
USED A SIMPLE MICROSCOPE
SAW LIVING MICROORGANISMS IN POND WATER
ROBERT HOOKE: FIRST TO USE THE TERM "CELL" (1663)
USED A COMPOUND MICROSCOPE TO SEE CORK CELL
NAMED AFTER A TERM FOR A "SMALL ROOM"
MATTHIAS SCHLEIDEN / THEODORE SCHWANN (1838)
USED IMPROVED COMPOUND MICROSCOPES
SAW THAT ALL ANIMALS AND PLANTS ARE MADE OF CELLS
CONTRIBUTED TO DEVELOPMENT OF CELL THEORY

5. parts of the MICROSCOPE
1. EYEPIECE: TOP OF BODY TUBE, MAGNIFIES IMAGE
2. BODY TUBE: HOLDS LENSES
3. ARM: HOLDS BODY TUBE TO BASE
4. NOSEPIECE: BOTTOM OF BODY TUBE, HOLDS OBJECTIVE(S)
5. STAGE CLIPS: HOLDS SLIDE IN PLACE
6. OBJECTIVE: BOTTOM OF BODY TUBE, FORMS IMAGE
7. STAGE STOP ADJUSTMENT
8. THE SLIDE
9. STAGE: SUPPORTS SLIDE OVER LIGHT SOURCE
10 COARSE FOCUS: LARGE ADJUSTMENTS IN FOCUS
11.DIAPHRAGM: CONTROLS LIGHT ENTERING STAGE
12. CONDENSER LENS / LIGHT SOURCE
13. FINE FOCUS: MAKES TINY CHANGES IN FOCUS
14. LIGHT SWITCH
15. BASE: SUPPORTS ENTIRE MICROSCOPE

6. procedure for the proper use of the MICROSCOPE
Follow these steps in order:
SET TO LOW POWER
MOVE STAGE UP TO NOSEPIECE
GET LIGHT, SET DIAPHRAGM
CENTER SLIDE ON STAGE AND SET CLIPS
FOCUS AT LOW POWER
PLACE POINTER AT CENTER OF VIEWED OBJECT
CAREFULLY MOVE TO HIGHER POWER
