									SEMESTER 1 FINAL EXAM REVIEW                                                 NAME: _________________

ANSWER THE FOLLOWING QUESTIONS:

              I Studied For _________________ For This Biology Final.
              I Expect To Receive a _______ to _______ Percent On This Test.
              TRUE/FALSE – I understand that there is a direct correlation between time studying
               and a grade I make on an Exam; that my teacher has given me the info and the help,
               and now it is up to me how I do; that studying for 30 minutes to two hours has the
               potential to increase my grade several percentage points. ___________________


KNOW    the PARTS OF THE MICROSCOPE!!
       Revolving nosepiece                                   Ocular lens
       3 objective lenses – Scanner, Low and High            Base and arm
       Stage                                                 Coarse Adjustment Knob
       Diaphragm                                             Fine Adjustment Knob

What are the THREE main steps to making a wet mount?
What is the Field of View on LOW POWER? ______________ on HIGH POWER? __________________
       oooooooooohh….more points  SCANNER? _________________ think!!!
What is the difference between primary and secondary and total magnification?

REMEMBER!!!!!!!
To figure out how wide a specimen is in MICRONS, you COUNT how many of them will fit side-by-side in
the Field of View and then divide this number INTO the number for the correct DIAMETER of the field of
view for the lens you are using.

Example, I think that 25 units of the specimen will fit side-by-side in my viewing circle on LOW power. So I
divide 1500 (the low power field of view) by 25 AND I get………

        60? I am doing this at 5:30 in the morning…..I think that this is right!!!


Which knob do I use if I am using SCANNER or HIGH Power? WHY??
Which knob do I use if I am using HIGH POWER? WHY?

COMPLETE THE CHART: (F.O.V. = Field of VIEW)

        OBJECTIVE LENS        POWER           F.O.V in millimeters (mm)         F.O.V in MICRONS
