Grade 8 Science Cell Biology Building Project Aim: Students will demonstrate their understanding of the components and functions of either a plant or animal cell. Expectations: With your team of three (3), build a three dimensional cell model. Get creative with materials. They can include large Styrofoam spheres (pre-cut half spheres can be obtained from a craft store) or a shoebox for the cell shell, colored or plain Play dough or clear gelatin for the cytoplasm, colored chenille sticks (pipe cleaners), puff balls, buttons, yarn, pasta and other items to represent the cellular components. You get the idea! Encourage each other to be creative and use lots of different materials in your model. Endeavor to choose items to accurately represent each organelle in size, shape, and location. Guidelines: 1. Choose a plant or animal cell; 2. Make a list of components you would find in your cell. A plant cell would contain a cell wall, cell membrane, cytoplasm, nucleus, DNA, ribosomes, chloroplasts, Endoplasmic reticulum (smooth and rough), Golgi complex, ribosomes, lysosomes, and vacuoles. An animal cell would contain a cell membrane, cytoplasm, nucleus, DNA, mitochondria, endoplasmic reticulum (smooth and rough), ribosomes, Golgi complex, ribosomes, lysosomes, and vacuoles; 3. 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; 4. Label each of the components. Print out organelle names, cut them into small labels and use toothpicks to attach to each label with some tape; 5. Create a separate key that shows each of the cell components and describes its function in the cell; 6. Use the cell grading rubric to get maximum points for your project Restrictions: You may work in groups no larger than three. Ensure that your partner(s) are people that you know you can work with. Report any problems as they arise and Mr. Dewell will ensure they are dealt with promptly. If you are building a model, please ensure that no food is used in its construction. Assigned: Due: II. Assessment: You’ll be marked as follows: Group: Topic: Criteria Level 1 (52, 55, 58) Level 2 (62, 65, 68) Level 3 (72, 75, 78) Level 4 (84, 88, 96) Understanding of Material - developing - developing with some inconsistencies - solid with only a few errors and/or omissions - thorough with exceptional insight Project Quality - incomplete - complete with noticeable gaps - complete and strong in quality and detail - complete, superb quality and exceptional detail Contribution (Individual) - minimal - considerable - strong - superb Personal Use of Work Time - focus and organization need considerable improvement - showed some organization and focus on task at hand - frequently organized and focused on task at hand - consistently organized and focused on work Personal Contribution to Product - minimal - considerable - strong - superb Personal Contribution to Process - valued only own ideas or did not share ideas - listened to others - encouraged contributions of others - central force in bringing together group members and their ideas Overall Grade: _________ Individual Grades: _______________________ _______________________ _______________________
