LEARNING OUTCOME #3: Investigate and explain the science of image formation and vision,
and interpret related technologies
1. Make a cross-sectional 3D model of a camera eye out of recycled material.
2. Label of the components of the eye on the diagram below, the 3D model, and the 2D
diagrams that you need to create
3. Use a small object or picture with your 3D model to show how light travels from the
object into the eye in order for you to see the image of the object. Use at least four
pieces of string to show the light rays from the object to your eye
4. From your model explain how the brain is related to your vision.
5. Make two cross sectional ray diagrams of the eye on two separate pieces of paper. One
piece of paper will show near-sightedness, the other will show far-sightedness.
6. On the two paper diagrams provide another diagram to show what lens would fix the
problem and how it fixes the problem.

Labeling of
Model
Four or more labels are
not labeled correctly or
are missing.
Three labels are not
labeled correctly or are
missing.
One or two labels are
not labeled correctly or
are missing.
All labeling is present
and done correctly
NOTHING is missing
Three or more parts of
the human eye are
placed incorrectly
according to what we
learned in class
One or two parts of the
human eye are placed
incorrectly according to
what we learned in
class
Placement of all the
parts of the human eye
are done correctly
according to what we
learned in class
Light ray
diagram for how
an eye processes
an object
NEITHER the projection
of rays NOR the
translation of the object
the eye is seeing are
correct.
Using a more detailed
object to correctly
project FOUR rays in
order to show the
process of sight
Size and
representation
of the parts of
the eye
NONE of the parts of
the human eye are of
appropriate size in
comparison to the other
parts.
Using an object you
EITHER correctly project
FOUR rays OR correctly
translate the object the
eye is seeing but not
both
FEW of the parts of the
human eye are of
appropriate size in
comparison to the other
parts.
Placement of all the
parts of the human eye
studied in class are
correct INCLUDING
extra parts and detail
outside of what was
expected to know
Using a more detailed
object to correctly
project MORE THAN
FOUR rays in order to
show the process of
sight
ALL parts of the human
eye are of appropriate
size in comparison to
the other parts.
Paper diagram (rough
work) is not included.
Paper diagram (rough
work) is lacking detail
and will not be
beneficial in creating
your project
Paper diagram (rough
work) is accurate and
provides a good
reference for creating
your project
EITHER the diagram is
not provided OR no
evidence provided to
show understanding of
the near sighted eye
and corrective lenses.
Unable to demonstrate
an accurate
understanding of BOTH
near sightedness with
ray diagrams and the
proper corrective lenses
needed to correct the
problem
Unable to demonstrate
an accurate
understanding of BOTH
far sightedness with ray
diagrams and the
proper corrective lenses
needed to correct the
problem
EITHER the diagram of
near sighted eye with
ray diagram is correct
OR the ray diagram
showing proper
corrective lenses is
correct.

EITHER the diagram is
not provided OR no

show understanding of
the far sighted eye and
corrective lenses.
MOST of the parts of
the human eye are of
appropriate size in
comparison to the other
parts.
EITHER the diagram of
far sighted eye with ray
diagram is correct OR
the ray diagram
showing proper

Paper diagram (rough
work) is very detailed
and accurate and
includes all things
mentioned in class AND
MORE providing a great
reference for creating
your project
BOTH the diagram of
near sighted eye with
ray diagram and the ray
diagram showing
proper corrective lenses
are correct.
BOTH the diagram of far
sighted eye with ray
diagram and the ray
diagram showing
proper corrective lenses
are correct.
