A CELL IS THE BASIC BUILDING BLOCK OF LIFE. IT CARRIES ALL OF OUR GENETIC INFORMATION. WE HAVE TRILLIONS OF CELLS IN OUR BODIES.
4
ALL LIVING THINGS ARE COMPOSED OF CELLS. CELLS ARE THE BASIC UNIT AND STRUCTURE OF ALL LIVING THINGS. ALL CELLS ARE PRODUCED FROM OTHER CELLS.
5
A MICROSCOPE IS ANY DEVICE USED TO MAKE SMALL OBJECTS SEEM LARGER. A COMPOUND MICROSCOPE IS ANY LIGHT MICROSCOPE THAT HAS MORE THAN ONE LENS.
6
ROBERT HOOKE ANTON VAN LEEUWENHOEK IMPROVED ON THE COMPOUND MICROSCOPE. ONE OF THE FIRST PEOPLE TO OBSERVE CELLS. CREATED A SIMPLE MICROSCOPE. OBSERVED MANY ONE- CELLED ORGANISMS.
7
MICROSCOPES MAGNIFY OBJECTS BY BENDING THE LIGHT THAT PASSES THROUGH THEIR LENSES. BENT LENSES ARE CALLED CONVEX LENSES. SOMETIMES MICROSCOPES NEED TO BE ADJUSTED FOR SHARPER RESOLUTION.
8
1. EYE PIECE: THIS IS WHAT YOU LOOK THROUGH INTO THE MICROSCOPE. 2. ARM: USE ONE HAND TO HOLD THIS PART OF THE MICROSCOPE WHEN MOVING IT. 3. FINE ADJUSTMENT: THIS MOVES YOUR SPECIMEN UP AND DOWN BUT JUST A TINY BIT. 4. COURSE ADJUSTMENT: THIS MOVES YOUR SPECIMEN UP AND DOWN A LOT.
9
5. OBJECTIVE LENS: THESE ARE WHAT MAGNIFY YOUR SPECIMENS. THERE ARE THREE ON OUR MICROSCOPES. THEY CAN MAGNIFY 40X, 100X AND 400X. 6. STAGE: THIS IS WHERE YOUR SPECIMEN SITS. 7. DIAPHRAGM: THIS ALLOWS LIGHT TO PASS THROUGH. 8. LIGHT: ILLUMINATES YOUR SPECIMEN.
10
9. BASE: USE YOUR OTHER HAND TO HOLD THIS WHEN MOVING A MICROSCOPE. 10. STAGE CLIPS: THESE HOLD YOUR SPECIMEN IN PLACE.
11
A. SLIDEB. SLIDE COVER MADE OF GLASS. THIS IS WHERE YOU PLACE YOUR SPECIMEN. MADE OF PLASTIC YOU COVER YOUR SPECIMEN WITH THIS.
12
C. CASED. LENS WHERE THE LENSES REST WHEN CLOSED. WHERE YOU HOLD WHEN USING THE HANDLENS. MAGNIFIES OBJECTS.
13
DRY SLIDES HAVE DRY SPECIMENS. PLACE YOUR SPECIMEN ON YOUR SLIDE AND COVER WITH A SLIDE COVER.
14
PLACE SPECIMEN ONTO SLIDE WITH DROPPER. PLACE ONE DROP OF BLEACH OR DYE SOLUTION (OR BOTH OR NONE) ONTO SPECIMEN. COVER WITH SLIDE COVER.
15
PLUG IN. TURN ON. PLACE SLIDE UNDER SLIDE CLIPS. CHOOSE YOUR OBJECTIVE LENS MAGNIFICATION. ADJUST COSRSE ADJUSTMENT UNTIL YOU CAN SEE YOUR SPECIMEN. ADJUST FINE ADJUSTMENT UNTIL YOU CAN SEE YOUR SPECIMEN VERY CLEARLY.
