Cell Analogy Project Project Due Date: Tuesday March 24th, 2009 Purpose: To demonstrate your knowledge of cells, their parts, and their parts’ functions by constructing an analogy collage from materials found through research. Requirements for a collage: 1. The collage must be carefully drawn on sturdy poster paper or white cardboard. 2. The collage must be of a typical plant or animal cell. You may not make a collage of a single cell organism. 3. Label the back of your collage with your name, due date, and class. 4. All writing (titles, structure names, statements, etc.) on the collage must be typed. 5. Your collage must contain all required cell structures. 6. Your cell drawing must be hand-drawn, using different colors for the different cell structures. 7. All cell structures must be labeled with their correct names. 8. For each cell structure, you must have a picture or photo of another object (machine or structure or living thing) that has a function analogous to the organelle’s function. a. All analogous pictures must have a pointer or line to their matching cell structure. b. Lines must be drawn straight. 9. Next to the analogous picture write a statement that includes a. Why and how the object in the picture is analogous to the organelle’s function. The statement should include the organelle’s function. i. For example, if a fingernail was an organelle, I might choose a picture of a roof. Next to the picture of the roof, I would write, “A fingernail provides protection for the soft tissues of the finger underneath it. A person’s finger is very important for sensing and for picking up objects. A roof also protects the contents of the house – those structures and people living inside.” b. An original statement describing how the organelle’s structure is related to its function. i. For example, “a fingernail is curved to fit over the soft tissue of the finger and it’s made out of hard material to provide additional protection to the finger.” 10. The size of the collage must be 18” x 24” 11. Work should be that of the student only. Ideas from family and friends are acceptable but the statements and analogies must be original work of the student. 12. Researched sources (3 or more are required) must be included in a typed bibliography and pasted on the back of the Cell Analogy Poster. a. Wikipedia is not an acceptable source. Suggested Procedure: 1. First decide if you are going to make a plant or animal cell. 2. Your collage must include the following labeled parts. Cell membrane Nucleus Nucleolus Vacuole (central vacuole for plant cell) Ribosomes Cytoplasm Golgi Apparatus (aka, golgi bodies, golgi complex ) Smooth endoplasmic reticulum Rough endoplasmic reticulum Mitochondria Lysosome Cytoskeleton Centriole (animal cell only) Cell wall (plant cell only) Chloroplasts (plant cell only) 3. Tackle one (or two) organelles at a time a. Determine their function. b. Learn about their structure. c. Look through newspapers, magazines, books (just don’t cut pictures from books…a color photocopy is fine), or pictures on the internet). But, don’t just “google” the organelle’s name. Find a picture or photo of something that has a similar function to the organelle you’re working on. d. Cut out the picture or make a copy of it. e. Type an explanation (statement) of how your found object has a similar function to the function of the organelle. Type an explanation of how the organelle’s structure is related to its function. f. Double check your statements to make sure they’re correct, thorough, and original g. Do a, b, c, d and e for all organelles. 4. Draw your cell with all required structures. 5. Type and affix labels of the cell structure’s names. 6. Make pointers. 7. Attach your cut-out pictures and their supporting statements to the poster in their proper places. 8. Type your bibliography. 9. Put your name and required information on the back of the poster. 10. Be prepared to explain why you chose the analogous pictures for their organelles. Grading Standards You will be graded using the following rubric. The categories include: □ Cell structures: all included with an analogy □ Cell functions: you must have interpreted and explained the organelle’s function correctly □ Analogy: you must have chosen an appropriate picture for the organelle’s function. □ Structure/Function: you must have discovered the organelle’s structure and determined how it makes sense for its function. □ Neatness, spelling, grammar: All statements/writings must be typed, without spelling and/or grammar errors. Collage is done with care, without smudges, erasures. Overall, collage looks clean and neat. □ Visual appeal of collage, and original thinking. Analogies are unique and well researched. Student has stretched to find the “uncommon” analogies. □ Timeliness: Sign off sheet must be turned in on-time. Point penalty for late turn in (sign off sheet). Projects will not be accepted after Friday 10/16 Grading Rubric CATEGORY 9-10 8-9 7-8 <7 Cell structures Every item that Almost all items Most items (70- Less than 70% of the items included needs to be (80-90%) that 80%) that need to that need to be identified are Score multiple: 2x identified is present need to be be identified are present and have analogies and has an analogy. identified are present and have and/or it is not clear which It is clear which present and have an analogy.
