Name ____________________________________________________ Period ___________ Date ___________________ Cell Comparison Project You have embarked on a study of the cell. This project will allow you to communicate your understanding of the inner structures (organelles) of the eukaryotic cell and how those structures function interdependently. You will do this by comparing the organelles to a humanbuilt structure that people are more familiar with. Someone who doesn’t know much about a cell should be able to look at your project and get a good understanding of how all the parts work together to help a cell function. PROCEDURE 1. Choose a human-built structure to serve as the basis for your cell comparisons. The title of your poster will be “A Cell Is Like a….” In the blank space you will put the name of your human-built structure, such as a/an airport, football game, circus, shopping mall, etc. The poster will actually show your human built structure – NOT the cell. All the organelles you include in your poster will be described as part of this one human-built structure. You will then create a “Glog” (digital poster) that explains your cell comparison. The glog will describe and illustrate the comparisons you think up for why your cell is like the human-built structure that you chose. We will take part of two class periods to work in the Computer Lab at A257. We will meet here in the classroom first for warm up and other starters, then go as a class to the computer lab. Your project will be graded based on the rubric included with this packet (last page). 2. You will work individually to create the glog comparison of a cell. To begin your glog go to http://www.glogster.com. You will need to register if you’ve never used the site. • Click on the “Create Account” button (lower right). Follow instructions to register. Record your account nickname and password: Nickname _________________________ Password _________________________ • After you have registered, click on the “Create New Glog” button (center of page). • What will appear is a “sample” glog space. After looking around at the various examples on this page, you will want to delete the different parts and create your own content. 3. With your human structure in mind, begin working on filling out your glog. Glogster lets you capture images from the web, upload your own images from your own files, insert videos, sound, and text. You can also change the background “wallpaper” and much more! You may want to start with making your title. Here are some tips for navigating around Glogster: • Click on “text” to add the title to your poster and click on “image” to include a picture of the human built structure you choose. You can search for an image online and then save it to your account. • Click on and use your own images that are saved on your computer (there is a maximum size requirement so large files may not work). • • Click on the item you want, and then click on to insert it into your poster. Click on any item in your Glog in order to edit it. Drag it to change its location on your poster. • Don’t forget to click on every once in awhile so that you don’t lose your work. Record your unique Glog name: _________________________ 4. Choose details from your human-built structure to compare to the structures and functions of the organelles of a cell. Often a cell is compared to a factory. A sample is attached—you will NOT use a factory for your comparison! The logic and richness of your comparisons will help you to learn better how a cell and its structures function together to enable the cell to grow, gain and use energy, produce wastes, divide, communicate, and all the other amazing functions it performs. 5. Next to each part of your human-built structure, you will insert a sentence that compares that part to a part of the cell (click on text and then drag the text box to where you want it). EXAMPLE: “Just as a shipping/receiving department determines what enters or leaves a factory, so the cell membrane selectively determines what can enter or leave a cell.” 6. Use at least 10 the following organelles/structures to include in your glog: Cell (plasma) membrane Cytoplasm Rough ER Mitochondria Nucleus Cytoskeleton Smooth ER Nucleolus Lysosome Peroxisome Golgi Apparatus Ribosome Vacuole Other Tips: • Click on to add media files from the web. Chloroplast (if plant cell) Cell Wall (if plant cell) Centriole (if animal cell) Cilia/Pili (if animal cell) Flagellum (if animal cell) • Click on to create new video audio, or still images. Here you can easily record your own voice tracks and add them to your Glog (if your computer has a microphone). You need an appropriate web cam in order to “grab” video files or still images. • Click the EDIT button to change colors or edit text. When you are finished, be sure to save your glog! You will also need to SHARE YOUR GLOG WITH YOUR TEACHER via Email. When the “What Next” box pops up (after you save), click on the “email” link right under the “+Share Glog” option. In the “Friend’s email” box, type my email address: [email protected] Type your name as well, so I know who sent me the fabulous glog! Also, SEND THE LINK TO YOURSELF via email so that you have a copy. 7. Strive for EXCELLENCE • PLAN BEFORE your start the poster. • Plan graphics that illustrate the comparison without overwhelming it. 8. Assessment: Your poster will be evaluated on the rubric included in the packet. Here is additional criteria/guidance to help you do your best job: • Comparison: Does your project have a unified central comparison of the cell? • Details: Have you included all of the cell organelles WITH details? • Clarity: Have you produced clear, correct labels for each detail? • Unity: Does your comparison show that the parts of the cell function together coherently—that the cell is using energy, growing, responding, etc.? • Technical Details: Does your poster have a title? Is your poster neat, attractive, and easy to read? Is your name on the poster? • Excellence: Is your poster creative, original, and interesting? Here is an example of comparisons of some cell parts to parts of a factory. You will have more parts than this. Factory Job Shipping and Receiving Dept. Cell Organelle Plasma Membrane CEO – Chief Executive Officer Factory Floor Nucleus Assembly Line Rough ER (Endoplasmic Reticulum) Golgi Apparatus Finishing and Packaging Dept. Cytoplasm Maintenance Crew Lysosomes Support Beams, Walls, Ceilings, Floor Power plant Cytoskeleton Hazardous Waste Removal Bags Peroxisomes Mitochondria Comparison Just as the shipping and receiving department controls what enters and leaves a factory, so the plasma membrane regulates what enters and leaves a cell. Just as the CEO directs all operations of the factory, so the nucleus and DNA controls all cell activities and what proteins will be made. Just as the factory floor holds all of the machinery and parts in the factory, so the cytoplasm is the where all the organelles and activity are found in the cell. Just as the assembly line is the place where the workers to their job in the factory, so the ER is the place where the ribosomes do their job of assembling proteins. Just as the finishing and packaging department prepares factory products for shipment, so the Golgi apparatus prepares the proteins for use or export out of the cell. Just as the maintenance crew cleans up all of the trash and recycles what can still be used, so the lysosomes break down the cell waste so the parts can be reused. Just as the support beams, walls, ceilings and floor of the factory support the whole building, so the cytoskeleton supports and maintains the shape of the cell. Just as the power plant provides energy for all the activities in the factory, so the mitochondria are the source of the ATP that is used for energy in cell processes. Just as special hazardous waste removal bags are used to get rid of dangerous waste in the factor, so the peroxisomes break down hazardous material such as hydrogen peroxide. NOTE: IF YOU HAVE DONE A CELL COMPARISON PROJECT IN MIDDLE SCHOOL, you may do one of the following instead. If you prefer to do the cell comparison, that is also fine. Check in with me to receive a specialized rubric. 1. Write a song or poem or story about the cell structures – include functions. 2. Make a video about the cell structures (perhaps a video of a skit you write and get performed by friends). Make sure you include functions. 3. Create a cell model (a sturdy one!) – label parts and give functions. 4. Any other creative idea that includes the functions of all the structures.
