Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits Introduction We will be learning about the differences and similarities between plant and animal cells through an engaging activity with fun, yummy candy! By participating in this activity you will be able to answer the following question: What are the similarities and differences between plant and animal cells? Not only will you learn through this experience, you will get to eat your cells afterwards

Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits The Task The question is asked to the students to identify what a plant and animal cell are. Although they have prior knowledge of these biological enzymes, they will be asked to reiterate this information and help to solve the original problem or question as to what these cells actually are. Students will be asked to create a Venn Diagram and elicit their prior knowledge as to what a plant and animal cell actually is. When reviewing this information, they will need to defend their stance and the answers that they included or did not include. Also, when it comes to actually creating a plant or animal cell, they will individually be able to decide which one to create, and what materials they should use for the process. During this tedious yet enjoyable tasks, the students will be asked to designed a cell of their choice; either a plant or animal cell. The materials will all be edible, so therefore, at the end, the students will be able to eat their product. This also falls under the category of a creative piece of artwork that the students have constructed, and will be forced to analyze as to what type of cell it actually is. The information that they learned previous in the Venn diagram activity, as well as using prior knowledge will allow them to transfer this into a more complex task. Although they already know for the most part what a cell is, their true knowledge of the subject matter will be compromised when they actually have to perform this complex task of making one themselves. This is a creative, fun process that allows individualism as well as personal insight. After the students have created their own cell, they will be asked to share with the entire class, explaining their cell, what materials represent what, and their overall experience.

Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits The Process Follow these instructions to complete the assignment For this activity grab the materials needed to complete a Animal Cell model. The cell that we will be creating will be entirely edible. First, you will need to get something that will serve as a cell wall that covers the entire outside of a cell. “The cell wall is the outer structure of the cell that is generally rigid and surrounds the membrane of the cell. It keeps the cell in place, and is what gives it it’s shape.”2. Once we have the outside of the cell finished, we will have to start working on the inside the cell. “Remember that everything we use has to be edible, so when we are making the inside layer, it has to be something flexible and very thin. This will represent the cell membrane. The cell membrane surrounds the cell and directs materials into and out of the cell.”3. Next, comes the cytoplasm, which is another part of the inside of the cell. This is a jellylike material, so out of the food materials in front of you, which one could you use for this? The cytoplasm fills the space inside the cell. Most cell parts are within the cytoplasm and appear to float around.4. Inside of the cytoplasm lays one of the most important things that is necessary for cell functions. It is the nucleus, which controls all cell activities. The nucleus makes the cell grow, develop and divide.5. Also inside the cytoplasm are two vacuoles. The vacuoles should be Vacuole is a storage area for either material the cell needs before it turns into waste. Plant cells have fewer and larger vacuoles than animal cells. Most plant cells only have one vacuole.6. Chloroplasts are something that make plants cells very different from animal cells. They are what give the plan cells their green color and are used for making food. Scatter a few small, green pieces in the cytoplasm. This green food will represent chloroplasts. They are scattered randomly throughout the cytoplasm. Take a few small edible green candies and make them the chloroplasts.7. Next to the chloroplasts are mitochondria. Even in animal cells, there are mitochondria because they are necessary powerhouses for energy in a cell.8. Now that your cell is complete, we have to label the parts of the cell, whether you decided to make an animal cell or a plant cell.9. Now comes the best part; YOU GET TO EAT IT! Refer to your Venn Diagram that we made during class if you have any questions about cell parts. you may also navigate through the following websites to help with background information as a guide to help create your model. http://www.kathimitc hell.com/cells.html http://www.biology4kids.com/files/cell_main.html http://www.kathimitc hell.com/cells.html http://www.biology4kids.com/files/cell_main.html

An “A” is for exceptional work only Exceptional 4 Accomplished 3 Developing 2 Beginning 1 Score Student was able to differentiate between animal and plant cells The student was able to identify all differences between plant and animal cells. The student was able to identify most of the differences between cells The student was unable to identify most of the differences. The students did not know the difference between plant and animal cells Students will be able to recognize key terms in both types of cells The student was able to identify all key terms accurately In both cells The student was able to indentify most of the key terms in the cells The student was unable to identify most of the key terms Student was not able to identify any key terms in either cell Student was able to accurately construct a cell with the materials provided. The student was able to accurately construct a cell with the materials provided The student was able to construct most parts of the cells. The student was unable to construct most parts of the cell Student was not able to construct a cell accurately more

Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits Student Page Top Introduction Task Process Evaluation Conclusion Teacher page Credits Conclusion Now that you have completed the activity, you are now an expert in identifying plant and animal cells! This will help further your understanding and knowledge of how plants and animals effect the ecosystem! Check out how these students showed off what they knew about cells! http://www.youtube.com/watch?v=4M779dlWw4Q&feature=related http://www.youtube.com/watch?v=jtf7MKDBF60&feature=related
