3.  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.
