4. 13 Product Life Cycle If each container could talk about its life, about how it came to be a drink container, what would it say? Record your thoughts in your notebook.

5. 13 Product Life Cycle Read the introduction and look for key ideas

6. 13 Product Life Cycle How can a life-cycle diagram be used to make a decision about a product?

7. 13 Product Life Cycle Complete procedure step 1

8. 13 Product Life Cycle What do you see in these diagrams?

9. 13 Product Life Cycle Complete procedure steps 2-4

10. 13 Product Life Cycle Can you picture what the reading is describing? Share your thoughts with the class.

11. 13 Product Life Cycle What does this diagram show?

12. 13 Product Life Cycle Complete procedure step 5 Be sure to show the relationship between steps with arrows.

13. 13 Product Life Cycle SCORING GUIDE: Group Interaction

14. 13 Product Life Cycle Share your diagrams with the class What does the diagram you constructed show?

15. 13 Product Life Cycle Comparisons Look for comparisons between the life-cycle diagram from this activity and the bar graphs you made to represent information about each drink container in Activity 12.

16. 13 Product Life Cycle What information does a life-cycle diagram show that a bar graph does not? Share your thoughts with the class.

17. 13 Product Life Cycle Analysis question 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.

18. 13 Product Life Cycle Analysis question 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. b. the raw materials used to make the product run out. c. materials engineers design a way to manufacture the container with less waste produced.

19. 13 Product Life Cycle Analysis question 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.

20. 13 Product Life Cycle Analysis question 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.

21. 13 Product Life Cycle Analysis question 5 Reflection: Based on what you’ve learned in this activity, do you think that the life cycle of a product should be included on the label? Explain.

22. 13 Product Life Cycle Green chemistry guidelines What do you see in these life cycles that could be changed to make a product greener?

23. 13 Product Life Cycle How can a life-cycle diagram be used to make a decision about a product?

24. 13 Product Life Cycle Key vocabulary definitions 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.

25. 13 Product Life Cycle Key vocabulary definitions Life-cycle diagram – A diagram that illustrates the stages in the manufacture, use, and disposal of a product. Raw material - 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.

26. 13 Product Life Cycle Key vocabulary definitions 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.

27. 13 Product Life Cycle Key vocabulary definitions End of life - The fourth and final stage in a product’s life cycle, when a product is no longer useful.
