CARE Curriculum Assessment Remediation Enrichment Grade LEVEL 7 Science CARE Assessment #3 CURRICULUM Body of Knowledge Big Idea Benchmark(s) Life Science 14: Organization and Development of Living Organisms SC.6.L.14.1 - Describe and identify patterns in the hierarchical organization of organisms from atoms to molecules and cells to tissues to organs to organ systems to organisms. SC.6.L.14.4 – Compare and contrast the structure and function of major organelles of plant and animal cells, including cell wall, cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria, and vacuoles. Video (5 minutes) – http://www.makemegenius.com/video_play.php?id=177&type=0 Show students this introductory video on the parts and function of animal cell for review. Sorting Activity – (5-7 minutes) Create an appropriate number of cards to be used in a class grouped into four students. Use index cards to write words to be used in sorting activity (laminate if possible for durability and store in Ziploc bag). o Plant Cell o Animal Cell o Cell Wall o Cell Membrane o Nucleus o Cytoplasm o Chloroplasts o Mitochondria o and Vacuoles Place students in groups of three - four (3-4) and have them sort the correct organelle under the appropriate cell (plant or animal). Complete a Venn Diagram by placing the organelles in the correct circle Plant or Animal and if they share an organelle place in the overlapped portion of the circles. Students should then complete a paragraph summary of what they’ve learned. Matching Activity – (5 minutes) Use index cards to create a matching activity. Created by KVM 10/14 Label on index card with each of the structures assessed (cell wall, cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria, and vacuoles) Label on an index card each of the following functions of the structures o Support and protection o Controls movement of materials in/out of cell o Controls cell activities o Supports and protects cell organelles o Powerhouse of cell – creates energy o Stores food, water, etc. o Uses energy from sun to make food for plants Have students match the function to the correct structure. Walk and correct student misconceptions and ask probing questions. ASSESSMENT Formative Assessment #4 – attached at the end of this document Formative Assessment #4 can also be found in BEEP REMEDIATION / RETEACH If students missed one to three questions from assessment 3 question #1-4 then: Send students to this website (http://www.biologyjunction.com/homeostasis_notes_bi.htm) and take notes on cell membrane and homeostasis Define Homeostasis for students so that they can understand the process of balancing out processes. o o Definition: The tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to stabilize health and functioning, regardless of the outside changing conditions (2) The ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes Play a game with students that creates the understanding that homeostasis is very similar to being in equilibrium. o Draw a balance on flip chart paper and have students use scenarios regarding energy from food, eliminating waste, and reproduction that allows students to write down what should happen if these changes were to occur in order for homeostasis to be maintained. (See below “Cellular Homeostasis” worksheet) o You may add as many scenarios specified to extracting energy from food, getting rid of waste, and reproducing as identified by test item specifications. If students missed one to three questions from assessment 3 question #5-7 then: Have students create a quick note guide in their science journals on Cell Theory: In the first Column have students write “Rationale” and in the second column “Evidence” Students will research in their textbooks and/or websites if computers are available evidence that supports each part of the cell theory. Created by KVM 10/14 If students missed one to three questions from assessment 3 question #8-10 then: Have students create a foldable of the structures in their science journal. (See below “Cell Structure and Function Foldable) If you are unable to make copies have students label 1-2 pages in their journals across the top left corner “Structures” and list the structures addressed in the benchmark. Create four (4) more columns: Plant and/or Animal Cell, Drawing, Function Once students have completed the information in the columns have them fold their pages to accommodate the information and then cut the rows that identify the seven structures. ENRICHMENT Use the websites to create a Cell City or a Cell Factory for presentation to the class. If students can think of any other analogy allow them to explore it as long as the analogy is applicable to concepts. They can create a poster, 3D model, or interactive web presentation for display. Background Information for students can be found at the sites listed below. o http://quizlet.com/410483/cell-organelles-and-their-functions-flash-cards/ o http://www.biologyjunction.com/cell_functions.htm - foldable Teacher Resources: Teachers use this webpage to get an idea of some correlations between the cell and city structures allow students to make correlations on their own. May be a group project if you wish. http://scorescience.humboldt.k12.ca.us/fast/teachers/Internauts/teacherpage.htm or http://sciencenetlinks.com/student-teacher-sheets/comparing-cell-factory-answer-key/ Grading: Use a rubric to grade student work.

Carbon Dioxide and Water are produced as waste products as cell use sugars to produce energy. Temperature of the external environment of the cell decreases by 1degree Celsius. Cells die causing a lack in the number and type of cell required to complete a specific function. Created by KVM 10/14 Cell Theory Rationale Evidence 1. All organisms are composed of cells. 2. All cells come from pre- existing cells 3. Cells are the basic unit of life.

Write details that tell how the subjects are alike where the rectangles overlap.
