Name ______________________ Date ____________

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
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
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
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
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
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
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
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

Oil extracted from deposits · The example specifies oil-based plastic, so its raw-material route begins with extracted oil.
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.
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.
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.
The joined materials may need separating first · Metal and plastic may need separate recovery processes. Their bond can make the required separation harder.
True · The same positive total is shared across twelve useful years rather than three. This does not compare operating or repair impacts.
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.
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.
