Do Now: 1. Get HW #2 (p.23-24) stamped! 2. Start p.25 Do Now “Think-Pair-Share” p. 25 Review Question #1: A student looks under the microscope and sees the following image. a) Is it a plant cell or an animal cell? -plant b) How do you know? (Evidence) - it has chloroplasts and cell wall; the shape is like “bricks”/rectangular Review Question #2: a) Is it eukaryote or prokaryote (look back at p. 2 for help)? - eukaryote b) How do you know? - it has a nucleus Reflection 1. Give Back Scientific Method Test 2. Complete the Test Reflection Sheet 3. Compare your Diagnostic Test Results to your Scientific Method Results Plant v. Animal Lab • Complete the Elodea/Cheek Cell Lab – Roles/Problem/Hypothesis (p.20) – Part A: Elodea plant (p21) – Part B: Cheek cells (p.21) – Part C: Conclusion Questions (p.22)…Use p.15-17 for help Elodea & Cheek Lab (p.20) • With your partner: Follow the directions and focus the specimen under the microscope. • Materials Manager: Who will be responsible for taking and returning materials? _____________________________ • Task Manager: Who will be responsible for reading each step out loud? _____________________________ • Do-er: ____________________________ Who will be responsible for ensuring that the microscope and slides are set up correctly? • Recorder: ___________________ Who will ensure that everyone is recording down their data? Elodea & Cheek Lab (p.20) • Problem: How do plant cells and animal cells differ? • Hypothesis: If I look at plant cells and animal cells under a microscope, then…(what differences do you expect to see?) _____________________________________ _____________________________________ _____________________________________ ___ Photos of Elodea Cells Photos of Cheek Cell Discussion - A Cell is Like… p.26 What do you notice/see in the picture? What do you think it is trying to show you? What questions does it raise? As a Class: Notes on Cell Analogies (p.27) SLIDE 1: 1. What is an analogy? • An analogy is used to compare two ‘like’ things 2. Why is a cell like a factory? • The job of a factory is to make a product (i.e. a bicycle, a cellphone, etc.) • The job of a cell is to make proteins (i.e. hemoglobin, melanin, insulin, etc.) Slide 2: p.27 • The cell wall is like the security gates because…. – It surrounds the factory and protects it just as a cell wall surrounds a plant cell and maintains structure. Slide 3: p.27 • The cell membrane is like the door because…. – It allows materials to enter and leave the factory Slide 4 p.27 1. The nucleus is like the CEO/boss’s office because…. – It’s where the boss resides. 2. The nucleolus is like the CEO/boss because… – He controls the factory and tells it what to do Slide 5: p.27 • The cytoplasm is like the factory floor because…. – It fills up the factory and connects each location to another Slide 6: p.27 • The Endoplasmic reticulum is like the assembly line because… – It moves the product (proteins) around Slide 7: p.28 • The Ribosomes is like the factory workers because… – They make the products (just like they make the protein) Slide 8: p.28 • The Vacuole is like the Kitchen because… – It stores food/water for the workers Slide 9: p.28 • The lysosomes are like the custodial staff because… – They clean up the factory’s waste materials, disinfect, etc. Slide 10: p.28 • The mitochondria is like the generator because… – It provides energy for the factory’s machines Exhibition Project (p.29) • Your goal: To create your own cell analogy. Part A. Cell Analogy Brainstorm Activity Directions: Decide what you and your partner(s) want to compare a cell to. For example, remember how we compared the cell to a factory? What other analogy can you come up with? Write your idea in the space provided below. If you change your mind in the middle of the brainstorm session, that is okay. However, you will need to finalize your cell analogy idea TODAY. A cell is like a __________________________________________________. (write your analogy here) Complete the table (p.29-30) for your analogy – get approved! AT LEAST 8 Organelles Is/are like… Nucleus Cytoplasm Cell membrane/ cell wall Vacuole Lysosomes Ribosomes Mitochondria Chloroplast Etc. etc. etc. My reason for this is… Part B. Create your Visual (p.31a) Create a visual representation of your analogy. You may create a poster or a 3-dimensional figure. (See sample poster on p.33). Your visual MUST include the following FOUR components: • Title “A cell is like ______________” • Your name and your partners name • Each picture/organelle labeled clearly • A brief description of why its an analogy. Example: • “The Gatorade is like the mitochondria because it provides energy to the players” Part C. Plan your Presentation(p.31b) Each person MUST explain 4 organelles -Fill out the graphic organizer, and plan for your presentation. Homework #3 due Thursday! Write a 1-2 page response to the following 4-5 questions: 1. What are cells? 2. What kinds of cells exist? 3. What are organelles? (Provide a few examples and explain their function) 4. How do plant cells differ from animal cells? 5. What analogy did you select for this project, and why? ***Note: If you need to look information up on the internet, remember to PARAPHRASE (put it in your OWN words. Students who copy off of the internet will automatically receive a zero on the written component. Your Goals for Tuesday 1. Do Now: Complete (p.34) 2. Finish your brainstorm (p.29-30) 3. Work on Visual (p. 31a) HW #3 tonight DUE Thursday!: p.32 Goals for Thursday 1. Do Now: Complete p. 35 2. Turn in your written piece (HW #3) 3. Finish your visual (p.31a) 4. Plan your presentation (31b) – You are presenting TOMORROW ! Tonight’s HW#4: p.36-38 (Part 1 review sheet) Goal for Friday 1. Do Now: Complete p. 39 2. Present your project 3.
