Cell Membrane Model Scoring Guide
Name_______________________
Core Content: SC-HS-3.4.3-Cells have specialized parts for the transport of materials and to maintain homeostasis.
Objectives: Students will create a model of a cell membrane to illustrate the structures and functions of the membrane
components.
Structures Required: 1. bilayer of phospholipids
4. cholesterol
2. glycolipids
5. peripheral proteins
3. glycoproteins
6. integral protein
Criteria
Outstanding 10
Pretty Good 7
Good 4
Needs work 1
Components
All components are
included
Model and explanations
indicate a very clear
and accurate
understanding of
scientific principles
underlying the
construction
Missing 1 component
Missing 2 components
Model and explanations
indicate a clear and
mostly accurate
understanding of
scientific principles
underlying the
construction
Very neat
Great attention in
construction process so
that the model is neat
and attractive. Model
clearly demonstrates
that tremendous effort
was put into its
planning, design and
construction
Uses creative materials
and design is original;
different materials are
used for each
component
All structures and
functions are clearly
identified ON THE
MODEL.
All structures are easily
identifiable.
Pretty neat
Model clearly
demonstrates that
much effort was put
into its planning, design
and construction, but 12 details could hve
been refined for a more
attractive product.
Model and explanations
indicate some
understanding of
scientific principles
underlying the
construction.
Misunderstandings/mis
conceptions are
obvious.
Good
Construction lacks
attention, lack of effort
is evident in planning,
design and
construction. 3-4
details could have been
refined for a more
attractive product.
Missing more than 2
important components.
Model and explanations
indicate lack of
understanding of
scientific principles
underlying the
construction.
Misunderstandings/mis
conceptions very are
obvious.
Needs work
Construction appears
careless or haphazard
and demonstrates little
effort in planning,
design and
construction. Many
details need refinement
for an attractive
product.
Lacks creative use of
materials and design is
not original; different
materials are not used
for each component.
Labels lack information
and is not identified on
the model.
