Vetted sources picked for today's question. Skim these before you take a position or start the work, so your argument and evidence are grounded.
- CER:
- Claim, Evidence, Reasoning — make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure — the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities — you open it through Schoology.

💡 Big idea: Scientific research depends on model organisms, but their use raises ethical questions about animal welfare and research validity.
- 0-8Read the model-organism prompt; assign stakeholder roles to groups
- 8-22Group prep: list 2 justifications and 2 concerns from your stakeholder view
- 22-40Debate round 1: each group states its strongest justification
- 40-55Rebuttal round: each group responds to one opposing claim
- 55-70Individual writing: personal stance with one supporting reason
- 70-80Pair-share stances and submit exit ticket
- • A tiny transparent worm has helped scientists win multiple Nobel Prizes in medicine.
- • Today you will decide whether using that worm, and others like it, is ethically justified.
- • Bioethics debate sharpens your ability to evaluate evidence and communicate reasoning clearly.
- • You will leave with a written, reasoned stance you can defend.
- 1Read a short prompt on why scientists use model organisms.
- 2Form groups representing researchers, ethicists, and patient advocates.
- 3List two justifications and two concerns about animal models.
- 4Exchange one rebuttal with an opposing group.
- 5Write your personal stance with one supporting reason.
- • Each student articulates a stance backed by a reason.
- • Groups surface at least one real ethical tradeoff.
- • Model organisms like C. elegans are used because they share conserved biological pathways with humans.
- • Research ethics weighs scientific benefit against potential harm to living subjects.
- • Understanding why we use model organisms connects to Microbiology and Evaluate Body Systems WebXam domains.

Unit 2.2 Research Model: Model organisms, C. elegans, neurotransmitters/hormones, scientific literature, research poster. · Animal research ethics debate
Day 1 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open Lesson 2.2 Everything Endocrine or Lesson 2.3 Challenge Accepted in myPLTW and complete any activity or reflection prompt assigned for today's model-organism ethics debate.
Mark the activity complete in myPLTW after submitting your exit ticket on C. elegans research ethics.
You finished the endocrine week; today begins the research-design phase bridging Lessons 2.2 and 2.3, and the task should be checked off.
Note or screenshot of completion status for your tracker.
All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.
