3B12 Check Write up – 5 points Title and ChallengeYour choice for a new drink container – 5 pointsData table – 5 pointsInformation in the data table – 15 pointsAll the information from the cards are listed on the table.Analysis 1 through 4 – 8 points (2 points each)Key Points – 5 points ( 1 point each)Vocabulary – 3 points ( 1 point each)Total = 46 points
4B13 Product Life Cycle B12 Vocabulary Evidence – previously defined Properties - previously definedTrade-offs - previously definedMaterials - Physical substances used to make things.Materials Engineer - Someone who uses the characteristics of existing materials to design new products.Materials Scientist - Someone who studies the characteristics and uses of various materials, such as metals, ceramics, and plastics.
5B13 Product Life CycleIf each container could talk about its life, what would it say?Materials Engineers use the term “life” to describe the stages a product goes through from its origins as raw materials until it’s been disposed of.Read the Background and Challenge on page B-7Write up the activity in your lab notebook.TitleChallengeSafetyProcedure – Follow the steps and record information as needed.
6Do Now for 10/28/13 Take out B13 materials. HW: Complete Analysis 1 through 5
7B13 Product Life CycleToday’s Target: I will be able to state the various stages of the life cycle diagram.End of life/disposal of plasticComplete steps 2 through 5Analysis 1 through 5
8B13 Product Life Cycle Complete Procedure step 1 together. Life cycle diagramWhat do you see in these diagrams?How are glass bottles made?How is glass recycled?
9B13 Product Life Cycle Complete steps 2 through 4 Read about your assigned product (either aluminum or plastic)As you read, fill out sheet 13.1 Stages in the Life Cycle of a Product. Express your answers in your OWN words.Complete step 5 – Life cycle diagramTake the information you gathered about the life cycle of your product, and use it to create a life cycle diagram.Make sure you include the arrows showing how different stages are connected.Show the inputs and outputs at each stage.Detailed inputs and outputs need to be listed.Draw the diagram in your lab book.
10B13 Product Life Cycle Analysis Complete lab report for B13 Use your diagram to answer analysis 1 through 5.Complete lab report for B13TitleChallengeSafetyCompleted Data Table (Student sheet 13.1)Copy of Life Cycle Diagram in your lab bookAnalysis 1 through 5
11Exit TicketWhich stage of the product life cycle is the most important and why do you think that?
12B13 Product Life Cycle Design a life cycle diagram Answer analysis questions
161. For the drink container you were assigned: a. What are its raw materials?b. Does the product have more than one end-of-lifeoption? Explain.PlasticRaw Materials: petroleum, natural gasEnd-of-life options: landfill, recycle someAluminumRaw materials: bauxite, sodium phosphate solutionEnd-of-life options: recycle, landfill
17a. the demand for the drink container increases. 2. Use your life-cycle diagram to explain what would happen to all of the other stages in the life cycle of the drink container if:a. the demand for the drink container increases.Need for more raw materials, more energy needed to gather raw materialsMore energy needed to manufacture the material and the containersMore waste produced during manufacturingMore used containers sitting in landfills
18b. the raw materials used to make the product run out. No materials to make the productNo waste produced from manufacturingCompanies need to find other materials to make the containersNeed to rely on recycled materials onlyNo more containers added to the landfills
19c. materials engineers design a way to manufacture the container with less waste produced. Less raw materials needed from the earthLess waste produced
20c. a person buying a bottle of sports drink in a store. 3. Explain why or why not a life-cycle diagram would be a useful tool for:a. the director of a drink company who wants to choose a container for a new drink.b. a materials scientist working to reduce the negative impact a drink container has on the environment.c. a person buying a bottle of sports drink in a store.in each case the life-cycle diagram would help the person to see the steps that go into the entire life of the product. Which in turn helps when making an informed decision.
214. Look at the life cycle of a product shown on Student Sheet 13 4. Look at the life cycle of a product shown on Student Sheet 13.1, “Stages in the Life Cycle of a Product.” Using the “Green Chemistry Guidelines” on Student Sheet 13.2, make a list of ways to reduce the negative environmental impact of this product.Reducing the amount of raw materials needed at each stage.Reducing the amount of materials needed as inputs in the manufacturing stage.Reducing the amount of waste produced at each stage.Increasing the amount of materials that are recycled to decrease the volume of raw materials needed at the manufacturing stage.Accept any suggestion that would reduce energy and resources as inputs and reduce the amounts of waste as outputs.
22B13 Product Life Cycle Key Points A material has characteristic properties.Technological solutions have intended benefits and unintended consequences. Some consequences can be predicted, and others cannot.Diagrams and models can demonstrate scientific concepts.
23B13 Product Life Cycle Vocabulary life cycle - The progression through a number of steps or different stages in the manufacture, use, and disposal of a product. For example, obtaining and refining a copper ore, making a penny, using a penny, and the eventual corroding of the penny. In animals and plants, life cycle refers to the developmental stages they pass through from birth to death.Raw materials - The first stage of four stages in a product’s life cycle. Raw materials need to be extracted from the earth in order to manufacture a product.
24Manufacturing - The second stage of four stages in a product’s life cycle. It is when the product is created from raw materials.Useful life - The third stage of four stages in a product’s life cycle. This is the time that a manufactured product may be used productively.End of life - The fourth and final stage in a product’s life cycle, when a product is no longer useful.
25B13 lab Check –Trade with someone who does not have the same material as you. Write up – 5 pointsTitle, ChallengeCompleted Data Table (Student sheet 13.1) – 5 pointsCopy of Life Cycle Diagram in your lab book pointsDoes the diagram list all the stages? 5 pointsDoes the diagram show detailed inputs and outputs at each stage? 5 pointsDo you understand the life cycle of this product after reading this life cycle diagram? 5 pointsAnalysis 1 through 5 – 10 pointsKey Points – 3 PointsVocabulary – 5 pointsTotal = 43 points
