CELL MODEL PROJECT - HONORS LIFE SCIENCE
- 7th GRADE
PROJECT REQUIREMENTS:
A. Research a specific type of cell and make a model of that cell.
Model Requirements:
1. The model will include all the parts we covered in class and any parts
unique to that type of cell. For example, some special parts of nerve cells
might be dendrites, the axon and a myelin sheath.
2. The parts should be accurate for shape, size and location inside the cell.
They should look similar to the diagrams you find for your particular type
of cell. The parts should reflect the relative size inside a real cell. For
example, the nucleus should be very large compared to the ribosomes.
3. All parts should be three-dimensional.
4. All parts should be labeled clearly and with correct spelling. If your
model is difficult to label, draw a diagram of your model with the parts
identified or use a key.
5. The model will be large enough to easily distinguish all the parts from the
back of the classroom, but NO larger than a standard poster board.
6. The model is sturdy and neat.
7. Each person on the Building Team must contribute materials toward the
project and take part in the building process.
B. A one page written report about your cell and a bibliography.
Report Requirements:
1. The report should describe the special features of the cell shown in your
model. How does your cell differ from the generalized plant or animal
cell?
2. If part of a multi-cellular organism:
i. In what kind of organism is this cell found?
ii. What specialized organelles are found in this cell?
iii. What is the function of this cell?
iv. How does its function fit in with the function of other cells to
work in tissue or an organ?
v. How does this cell’s function help keep the organism alive?
3. If a unicellular organism:
i. What type of organism is this cell?
ii. Where does this organism live and under what conditions?
iii. What specialized organelles are found in this cell?
iv. How do these specialized organelles help keep the organism
alive?

4. Your report should include at least three interesting facts about your cell.
5. Your report should be typed with 12-14 point readable font and 1.5 spaces. It
should be neat and clean.
6. Your paper should be written in complete sentences with no spelling or grammar
errors. Use spell check but make sure that it isn’t changing the word to
something different.
7. Include a works cited of your sources on a separate sheet of paper. You must
have at least two sources.
C. Work Log:
Your group will keep a work log detailing your goals and what work you
complete. You must provide written evidence in you log that each
person contributed equally to all phases of the project. Your log will be
checked at the end of each work session.
D. Oral Presentation:
Each group will present their model in an oral presentation. Each person
will have an equal number of parts to present. They will describe their
type of cell, point to the parts and tell some facts and interesting
information about their cell. (Each person gets an individual grade.)
E. Tips and Tricks:
1. Do NOT spend anything on your project. Try and construct it entirely out
of recycled materials. For creative inspiration look at the projects in your
classroom.
2. Remember, most cells have the basic parts we learned in class even if the
diagrams you find do not label them. If your research fails to show the
regular cell parts assume they look like and are placed in your chosen cell
like the diagrams on pages 68-75 in your textbook.
3. Do not limit your search to one source. One source may have some
details, another source a few more, etc. Vary your sources, i.e.
encyclopedias, books, magazines, the web, your textbook, high school or
college biology textbooks, medical books, and health encyclopedias.
4. As you learned in sixth grade, you must cite your sources at the end of
your report. You must use MLA standards to write your Works Cited.
You may use the resources at www.easybib.com to help you. Also
remember, the online school encyclopedias have given you the
bibliography in correct format at the end of each article – all you need to
do is copy and paste.
5. Please use the Harmony Middle School library, the Purcellville Library, for
books on your specialized cell. Also use the online websites provided to
you by Loudoun County Public Schools and any websites that end in .edu
or .gov or .org – these are most likely reputable websites
