💡 Big idea: When medical resources are scarce, society must decide on allocation principles that balance fairness, need, and outcome.

- 75-80Class share: which allocation principle came up most?
- • This week we go deep into the skeletal system: bone cells, fractures, and how bone heals.
- • Before we do that, here is the ethical puzzle this technology creates. Bone grafts are not unlimited. When supply runs short, who decides who gets one?
- • Today you build a principled argument for one allocation rule. Your CER must name a specific rule and defend it against the best objection.
- • This is also vocabulary building day. Listen for the terms autograft, allograft, and alloplast. They will appear on the WebXam.
- 1Read the prompt: when bone-graft material is scarce, who should receive it first?
- 2List two fair allocation rules and one risk of each.
- 3Choose a side and write a one-sentence claim with your reasoning.
- 4Debate in your John Carroll bioethics group and record the strongest counterpoint.
- 5Post a CER response defending your allocation principle.
- • You can propose and defend an allocation rule for scarce grafts.
- • You can respond to a fairness counter-argument.
- • Bone grafts can come from the patient (autograft), a donor (allograft), or synthetic/3D-printed materials (alloplast).
- • Allocation ethics asks whether decisions should be based on medical urgency, likelihood of benefit, or waiting-list order.
- • Pathologies like osteoporosis, osteosarcoma, and avascular necrosis may require bone grafts, making graft access a real clinical issue.

Unit 1.1 Bones: Bone structure/function, skeletal system, fractures, bone remodeling, repair technologies. · Bioethics: bone donation and 3D parts
Day 1 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open Lesson 1.1 Beginning with Bones in myPLTW and complete the introductory skeletal-system task; use facts from it (such as graft types) in your bone-allocation CER.
Mark the introductory task complete after posting your allocation CER.
You finished the anatomy-organization week; this begins the bone-biology content inside Lesson 1.1, and the task should be checked off today.
