  1. The lesson follows an oil-based plastic straw. Which raw-material source begins that example?

    • Oil extracted from deposits
    • Sand used to make the glass
    • Wood used to make the paper
  2. Which order matches the lesson's four-stage model of a product's life?

    • Raw material, use, manufacture, end of life
    • Manufacture, raw material, use, end of life
    • Raw material, manufacture, use, end of life
  3. Which arrangement helps someone reach and replace a worn part?

    • A glue-sealed case with no spares sold
    • A screw-fastened case with sold spares
    • A sealed case with a long-life promise
  4. Which route should an adult check for a used lithium-ion phone battery?

    • A service that accepts that battery type
    • An ordinary bin for paper plus packaging
    • A waste bin once the phone stops working
  5. Why can a bonded metal-and-plastic casing be harder to recycle than a casing made from one recyclable material?

    • Every bonded casing always uses extra material
    • These bonded materials go in one recycling bin
    • The joined materials may need separating first
  6. Assume the total impact of making a product and handling its end of life is positive and stays unchanged. Keeping it useful for twelve years instead of three lowers that total per year of use.

    Circle one:   True   False

  7. A maker says its gadget is repairable. Which evidence best tests that claim for a particular worn part?

    • A claim that no spare parts would ever be needed
    • A high price and a promise of good build quality
    • A safe repair test using an available spare part
  8. A gadget is glued shut and suitable spares are unavailable. Which conclusion is supported by those facts alone?

    • This maker intended this gadget to fail prematurely
    • Repair is hindered; the maker's intent is uncertain
    • Repair is impossible; no specialist could ever help

  1. Oil extracted from deposits · The example specifies oil-based plastic, so its raw-material route begins with extracted oil.
  2. Raw material, manufacture, use, end of life · Raw materials are supplied before manufacture. The product is then used and reaches its end-of-life stage.
  3. A screw-fastened case with sold spares · Screws can help provide access without damaging the case. Sold spares can provide the replacement. Safe repair still needs checking.
  4. A service that accepts that battery type · An adult should check current local instructions and an accepting battery or electronics service. Used lithium-ion batteries can still cause fires.
  5. The joined materials may need separating first · Metal and plastic may need separate recovery processes. Their bond can make the required separation harder.
  6. True · The same positive total is shared across twelve useful years rather than three. This does not compare operating or repair impacts.
  7. A safe repair test using an available spare part · A qualified person's repair test checks whether an available suitable spare can be fitted safely and restore function for that fault.
  8. Repair is hindered; the maker's intent is uncertain · The observations show repair barriers. They do not establish the maker's intention or rule out every specialist repair.
