Mr. Frazer’s Life Science Class Cell Model Project This project is due IN CLASS on _________________________. • Your assignment is to build a three dimensional (3D) cell model. Materials may be edible (food) or nonedible. You can include large styrofoam spheres (pre-cut half spheres can be obtained from a craft store like Michaels or Hobby Lobby) or a shoebox for the cell shell, colored or plain playdough or clear gelatin for the cytoplasm, colored pipeleaners, puff balls, buttons, yarn, pasta, candies, or and other items to represent the cellular components. Target or Walmart are great stores to visit because you could purchase both edible and nonedible components in one place. • You will work individually • I encourage you to be creative and use lots of different material in their model and that they should choose items to accurately represent each organelle in size, shape, and location. PROJECT GUIDELINES 1. Choose a plant or animal cell. 2. Make a list of components you would find in your cell. An animal cell would contain a cell membrane, cytoplasm, nucleus, DNA, mitochondria, endoplasmic reticulum (smooth and rough), ribosomes, golgi complex,ribosomes, lysosomes, and vacuoles. A plant cell would contain a cell wall, cell membrane, cytoplasm, nucleus, DNA, ribosomes, chloroplasts, endoplasmic reticulum (smooth and rough), golgi body, ribosomes, lysosomes, and vacuoles.. Select different materials to represent each of the organelles present in that cell. Shape and size the material to realistically resemble the organelle. Place each in its appropriate location in cell body. 3. Label each of the components. Print out or write the organelle names, cut them into small labels or pieces of paper and use toothpicks or other means to attach to each label with some tape. 4. Create a separate report that shows each of the cell components and describes its function in the cell. 5. Use the cell grading rubric to get maximum points for your project. 3-D Plant Cell Model Project Rubric Mr. Frazer’s Life Science Class Grading: You will initially start with 85 points. You will lose points for the following items: Missing an organelle (deduct 1 point for each organelle) = 10 total Missing a label on an organelle (deduct 1 point for each label) = 10 total Organelle is mislabeled (deduct 1 point for each mistake) = 10 total Missing the reference sheet (list of organelles and their functions) = 11 total No name on project (deduct 6 points) = 5 total Plant cell is not square (deduct 10 points) = 10 total Project is sloppy (deduct up to 15 points) = 15 total Project is late (deducted: 10 points per day) Project is not three-dimensional (deduct 25 points) = 25 total Remember: Your project grade is worth 85 points total. It is intended to help you better understand the cell and improve your grade. Please take this seriously and turn it in on time. Organelle Is present Labeled Function Total 1. Cell Wall 2.
