      Have you ever wondered why Americans are accused of using more energy and raw materials per
person than any other nation? Do you feel like you use a large amount of energy or raw materials on a day
to day basis? For most Americans the answer is probably "NO". Why this difference in how we perceive
ourselves vs. how the world sees us? One possible explanation is that most of the energy and raw materials
consumed by Americans is spent INDIRECTLY. That is, energy spent in processing the raw materials,
transportation both to plants and to stores, production at the plant, advertising, sales, and delivery to the
home. When we buy a pencil we don't think of the energy required during each step of the production of
that pencil.
1) For this worksheet you are to choose one "simple" product (pencil, paper clip, pen, spiral notebook,
      scissors, stapler, etc).
                                            Name of Product = _______________________
2) List all the different steps needed to obtain the raw materials, make the product, sell the product, and
       deliver the product; and that had to consume energy or raw materials.
3) Indicate where that energy or raw product went into your simple product.
      SAMPLE: (imagine that my product was a pencil)
      RAW MATERIALS         ENERGY CONSUMED                    WASTES PRODUCED
1. Cutting trees                    gas & human (chain saw)               carbon monoxide, carbon dioxide, blades
2. Hauling trees                   gas (trucks) & humans (driver)        carbon monoxide, carbon dioxide, tires
3. Sawmilling trees               electricity & humans                        heat, wood chips, carbon dioxide, blades
4. Shaping wood                  electricity & humans                        heat, wood chips, carbon dioxide, blades
5. Mining graphite                 gas (machines) & humans               carbon monoxide, carbon dioxide, slag
6. Shaping graphite              electricity & humans                        heat, soot, carbon dioxide, blades
7. Glueing graphite & wood   chemical, electricity, & human      heat, carbon dioxide, released chemicals
                                                       ETC……………

(NOTE --> Try to list a minimum of 20 different steps & feel free to do research.)
