7th Grade Life Science

Cell Model Project

Project:

You are to build a 3-D model of a plant or animal cell. This model can be based upon an actual cell (muscle, nerve, skin cell) or based on the generic cell found in textbooks. Do not base your model on the Bob Jones text we’re using. If necessary, I can supply a picture of a cell and its organelles.

Design Constraints:

The model must be no smaller than 20 cm x 20 cm x 15 cm.
The model must be no larger than 40 cm (l) x 30 cm (w) x 25 cm (h).
You should spend no more than $8 total on the project.
The model must include all of the following parts of the cell:

Cell membrane

Cell wall if plant cell

Chloroplasts if plant cell –4 each

Nucleus with pores in membrane

Mitochondria –1 each

Golgi body –1 each

Ribosomes –4 (2 on ER and 2 in cytoplasm)

Endoplasmic Reticulum (ER) –next to nucleus, Rough and Smooth

Vacuole –1 (large central vacuole if plant)

Lysosome –1

All the parts of the cell are to be labeled, preferably typed, or a key to be attached to the cell.
The inside of the cell must visible: either the cell can be “opened” or part of the cell membrane can be removed for viewing.
Bonus—show ribosome making a protein with mRNA and tRNA

Suggested materials

Shoe boxes macaroni pasta peanuts

Plastic wrap nuts/bolts M&M’s straws

Tissue paper toothpicks 2 lt. bottles pipe cleaners

Lg. Juice bottles seeds twigs fishing line

Please no liquids or Jell-O

Documentation

Submit final documentation on day model is due to be at school

CELL MODEL QUARTER PROJECT

Please turn in this information no later than Friday, November 20, 2009

What type of cell is your model?______________(plant, animal, skin cell?)

Where are you getting your ideas on how the organelles should look?

Please name book or website you are using.

What supplies do you think you will use? You may change your mind later but it should be noted in the documentation. Please include items such as paint, glue, etc.

Please make a sketch of your model.
