Slide 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 its been disposed of. Read the Background and
Challenge on page B-7 Write up the activity in your lab notebook.

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

Slide 15 Slide 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 Slide 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 Slide 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
Slide 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 Slide 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.
Slide 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. Slide 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. Slide 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 products life
cycle. Raw materials need to be extracted from the earth in order
to manufacture a product. Slide 24 Manufacturing - The second stage
of four stages in a products life cycle. It is when the product is
created from raw materials. Useful life - The third stage of four
stages in a products life cycle. This is the time that a
manufactured product may be used productively. End of life - The
fourth and final stage in a products life cycle, when a product is
no longer useful. Slide 25 B13 lab Check Trade with someone who
