10. Activating Prior
Knowledge
¡°Magnify the unseen world,
Intricate details unfurled.
Cells and creatures, big and small,
Revealed beneath the lens, we call.
Observing life in its tiny scope,
Scientific wonders, giving hope.
Concealed mysteries, now clear,
Optical marvels bring them near.
Patterns, structures, come alive,
Exploring realms that thrive.¡±

MAGNIFICATION
The factor by which a
microscope enlarges an
image. It is calculated by
multiplying the magnification
of the objective lens by
magnification of the eyepiece.
32. Unlocking Content Area
Vocabulary
RESOLUTION
The ability of a microscope
to distinguish two close
points as separate entities.
it determines the level of
detail and clarity that can
be observed in the
microscopic image.
34. Unlocking Content Area
Vocabulary
STAGE
The platform on which
the specimen is placed
for observation. It often
includes a mechanical
stage with controls to
move the specimen
precisely.
36. Unlocking Content Area
Vocabulary
EYEPIECE (OCULAR)
The lens at the top of the
microscope that you look
through to observe the
specimen. It further
magnifies the image
produced by the
objective lens.
40. Write the parts of the
microscope in the
corresponding
numbers.
Explicitation
43. The lens at the top of the
microscope that you look
through, usually with a
magnification of 10x or 15x.
Eyepiece (Ocular Lens)
44. The part of the microscope
that connects the base to
the head and the eyepiece
tube. It is used to carry the
microscope
Arm
45. Metal clips on the
stage that hold the
slide in place.
Stage Clips
46. A larger knob used for
focusing the
microscope. It moves
the stage or the body
tube up and down to
bring the specimen
into general focus.
Coarse
Adjustment Knob
47. A smaller knob used for
fine-tuning the focus of
the specimen after
using the coarse
adjustment knob. It
moves the stage slightly
to sharpen the image.
Fine Adjustment
Knob
48. The tube that connects
the eyepiece to the
microscope body.
Draw Tube
Draw
Tube
49. The part that holds two or
more objective lenses and
can be rotated to easily
change power
(magnification).
Revolving
Nosepiece
50. The lenses closest to the
specimen, that are
typically of varying
magnifications (e.g., 4x,
10x, 40x, 100x).
Objective
52. A rotating disk under the
stage with different sized
holes. It is used to vary
the intensity and size of
the cone of light that is
projected upward into
the slide.

67. How to handle a compound microscope
Turn the revolving nosepiece so that the lowest power
objective lens (eg. 4x) is clicked into position.
Place the microscope slide on the stage and fasten it with the
stage clips.
Look at the objective lens and the stage from the side and turn
the focus knob so the stage moves upward. Move it up as far as it
will go without letting the objective touch the coverslip.

68. How to handle a compound microscope
Look through the eyepiece and move the focus knob until the
image comes into focus.
Adjust the condenser and light intensity for the greatest
amount of light.

Move the microscope slide around until the sample is in
the center of the field of view.

69. How to handle a compound microscope
Use the focus knob to place the sample into focus and readjust
the condenser and light intensity for the clearest image.
When you have a clear image of your sample with the lowest
power objective, you can change to the next objective lenses.
You might need to readjust the sample into focus and/or
readjust the condenser and light intensity. Do not let the
objective lens touch the slide!
