Cell Grading Rubric
Grading rubric will look at the following qualities of your cell model:
Creativity and Design
- Animal or plant cell model is appropriate shape. Animal cells are round and plant cells are square.
- Construction is a 3-D model using four or more different media/materials. The model must be 3-D and not a drawing. Materials may be edible or nonedible. Be creative in choosing materials. Use your imagination and look for things around the house (buttons, chennile sticks, dried pasta, yarn, playdough, gelatin, candy of different shapes and sizes)
- Care is taken to choose materials that accurately represent each cellular component in shape, size and location in cell. For example, the mitochondria and chloroplasts are kidney-bean shaped and are roughly the a quarter of the size of the nucleus. The nucleus is round, located in the center of the cell body and should be the largest organelle in the cell model.
- Cell components for that particular cell (plant or animal) are present with none missing. Components are accurate as well. For example, mitochondria are found in animal cells but chloroplasts are found in plant cells.
- Cell components are labeled appropriately
- Separate key lists cellular components and their functions
Extra points for the following:
- Create a particular type of animal cell (muscle, nerve, bone, blood) with accurate representation of cellular components. Example: skeletal muscle cells have many nuclei; red blood cells have none because their nuclei pop out before entering the blood stream from the bone marrow.
- On a separate piece of paper give a simple explanation for photosynthesis and state which organelle is involved with this process.
Create a Stand for Cell Model
You may use a paper towel roll with tape or the top from a gift box to place your cell model on. You will want to tape or glue the bottom of your model to reduce wobbling and make it secure.
Cell Component Checklist
-endoplasmic reticulum (smooth and rough)
-ribosomes (on ER as well as free floating ribosomes in the cytoplasm)
- endoplasmic reticulum (smooth and rough ER)
- ribosomes (on ER as well as free floating in cytoplasm)
-chloroplasts (remember to make the chloroplasts green since they are filled with chlorophyll)
After learning the anatomy of the cell and its components, research the functions of each part. Quiz yourself or work with a study buddy to help you remember the functions. You will be expected to provide a key that describes the functions of each component on your cell model.
