The Incredible Edible Cell GOAL: Your task is to create a model of a cell that is made completely of edible things. That’s right… you will be able to eat this cell after you are through! In your journey, you will also create a paper describing the main parts of your cell, as well as create a blueprint of your cell and a table detailing the items you will use for construction. (If acquiring your products is a financial difficulty please see me for alternative arrangements). You must follow all directions completely in order to achieve the highest grade possible: 300 Project points ROLE: You are a super scientist trying to create a cell that will help others understand how the cell is organized. Your paper will serve as a journal explaining cell organization, structure and function. AUDIENCE: Your audience is young children who are learning about plant and animal cells and how they work. SITUATION: Your project must explain to your audience the locations, structures and functions of cell organelles in a way that is fun and in a language that is easy to understand. PRODUCT: Your project consists of three parts. For each of the three parts (depending on your cell selection), you must include the following cell organelles. CHOOSE ONE OF THE FOLLOWING: *ANIMAL CELL (round shape) 9 organelles total Cell Membrane Ribosome (free or on ER) Lysosome Cytoplasm Endoplasmic Reticulum Mitochondria Golgi Bodies Vacuole (few & small) Nucleus *PLANT CELL (square or rectangular shape) 11 organelles total Cell Membrane Ribosome (free or on ER) Lysosome Cytoplasm Mitochondria Endoplasmic Reticulum Golgi Bodies Chloroplast Cell Wall Vacuole (one & large) Nucleus (Nucleolus/Nuclear Membrane/DNA) Part 1: The Paper- 100 points EACH INDIVIDUAL must turn in a typed or neatly handwritten paper explaining all of the organelles discussed in class. The formatting of the paper must include: 1. An introduction in which you introduce what the project 2. A paragraph on each of the organelles consisting of FOUR sentences: a. One sentence describing what type of cell this organelle is found in EUKARYOTIC, PROKARYOTIC, PLANT or ANIMAL b. One sentence on the organelle’s structure (its appearance and/or location) c. One sentence on the organelle’s function (its job) d. One sentence explaining what would happen to the cell if the organelle was missing or absent from the cell. 3. A concluding paragraph in which you describe your thoughts on the project. ***Papers on Animal cells have 11 total paragraphs; Papers on Plant cells have 12 total paragraphs Part2: The Key and Blueprint- 100 points EACH TEAM must create a key for your edible cell model so that others can tell what cell part (organelle) your food represents. Use the pictures of cells and organelles in classroom and online textbooks and any cell notes to help you decide what foods would best represent each cell part. Food items should look similar to the structure of the organelles i.e. a nucleus is round and has a nucleolus inside so a jawbreaker cut in half with the small round center exposed would best represent the nucleus and nucleolus. The key must contain two parts in order for your team to receive full credit. The parts are as follows: 1. Key (50 points): Create a chart or table that states both food part and the organelle or cell part each food represents. This can be typed or neatly handwritten. 2. Blueprint (50 points): Create a drawing of what your cell model will look like when you have created it. It should be a drawing of a cell as a cookie/cake. The foods and which organelle the food represents must be clearly shown and labeled. You must make sure that organelle location is appropriate. This will act as your blueprint as you construct your cell model. Placement of organelles/food items must match between your blueprint and model. Part 3: The Model including Labels - 100 points This is the fun part! You need to build your cell model. Each part needs to be made of the food part listed on the data table. You will be graded on how accurate your model is and how close your actual model was to the drawing i.e. if the nucleus was in the middle of the drawing then the food nucleus needs to be in the middle of the model. The model must contain two parts in order to receive full credit. These parts are: 1. Labels (50 points): Each food item must have a label. The label must state on one side what organelle the food represents. The other side must have bulleted points that state the structure and function of the organelle. Labels must have a support like a flag so they can be fastened into your food items. For example: and wastes in and out Lets nutrients Cell Membrane Protects cell 2. Edible Cell (50 points): This is the actual model of the cell. You will be graded on how close the actual model is to the drawing made in Part 2 and you will be graded on content. You need to make sure that each item that was written in your data table is represented in the actual cell model. STANDARD: SL72b: Relate cell structures to basic cell functions You will be graded according to the rubric below. Four categories will be assessed as follows: Content: Paper: Does your paper describe the location, structure and function of each cell organelle listed in the product description? Do you have an introduction and closing paragraph? Table/Blueprint: Does your table list each organelle in the product description, its function, and the representing candy? Does your blueprint depict each organelle from the product description? Model: Does your model contain each organelle from the product description? Accuracy Is the information in your paper, blueprint, table, and labels presented correctly and accurately? Are the items used to construct your model accurate representations of the individual organelles (i.e. do they look like the organelles they represent)? Presentation Is the information in your paper, blueprint, table, and labels neatly handwritten or typed? Is your model constructed using the appropriate materials? Creativity Does your project represent your original thought? Is it creatively designed?
