Oct 8 / 9 Act B13 Product Life Cycle CH Q LEARNING TARGET: I can construct a life-cycle diagram of a product and use it to recommend ways to reduce the product’s negative impact on the environment CH Q How can a life-cycle diagram be used to make a decision about a product? VOCAB: next slide

life-cycle raw material manufacturing useful life end of life Changes / process of change starting "stuff“ / nature made / from the earth creating / making Functional / before throwing away when done using / through with it

DISCUSSION What would be the complete life story of a container if it could talk? raw material – manufacture – use - recycle? / end of life Challenge: Watch ‘How its Made?’

PROCEDURE AND DATA MATERIALS: PROCEDURE: Read on pg. B 8-10 and summarize DATA: WS 13.1 Stages in the Life Cycle of a Product WS 13.2 Green Chemistry Life Cycle Diagram

Compare Life cycle diagrams POST DISCUSSION Compare Life cycle diagrams What information does a life-cycle diagram show that a bar graph does not? shows a process over time – not just one point in time What do you see in these life-cycles that could be changed to make a product greener? reduce energy needs, reduce – reuse – recycle – (renew) videos

POST DISCUSSION - Day 2 Review statements on back of WS, - Agree / Disagree -Explain reasoning based on class research Again: What do you see in these life-cycles that could be changed to make a product greener?

ANALYSIS - Discuss and answer Q 2 & 5 on pg. B- 12 ANS CHALLENGE Q How can a life-cycle diagram be used to make a decision about a product? A: life-cycle shows ALL needs of container from beginning to end helping make more responsible decision (but no data – graphs do that) HOMEWORK 1. WS 13.2
