5. B13 Product Life Cycle • If 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-7 • Write up the activity in your lab notebook. • Title • Challenge • Safety • Procedure – Follow the steps and record information as needed.

13. Do Now for 10/29/13 • Take out B13 • HW: None

14. Today’s Target: : I will be able to state the various stages of the life cycle diagram. • What else can happen to plastic • Check HW and go over analysis • Key Points and Vocabulary • Lab Check for B13

16. 1. For the drink container you were assigned: • a. What are its raw materials? • b. Does the product have more than one end-of-life option? Explain. • Plastic • Raw Materials: petroleum, natural gas • End-of-life options: landfill, recycle some • Aluminum • Raw materials: bauxite, sodium phosphate solution • End-of-life options: recycle, landfill

17. 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 materials • More energy needed to manufacture the material and the containers • More waste produced during manufacturing • More used containers sitting in landfills

18. b. the raw materials used to make the product run out. • No materials to make the product • No waste produced from manufacturing • Companies need to find other materials to make the containers • Need to rely on recycled materials only • No more containers added to the landfills

19. c. materials engineers design a way to manufacture the container with less waste produced. • Less raw materials needed from the earth • Less waste produced

20. 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.

21. 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.

22. B13 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.

23. B13 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’slife cycle. Raw materials need to be extracted from the earth in order to manufacture a product.

24. Manufacturing - 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.

25.
