What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Worked CER on a parallel case (newborn genetic screening)
Completes: Parallel model showing the full CER format: a claim on whether an untreatable-condition genetic screen should be added to the newborn panel, two pieces of evidence, reasoning, and a three-sentence reflection. Students copy the structure, not the answer.

Parallel case (not today's prompt): Should a genetic screen for a serious adult-onset condition that has no childhood treatment be added to the standard newborn screening panel that every baby receives at birth?\n\nClaim: A genetic screen for an untreatable adult-onset condition should be offered to parents as an optional add-on, but it should not be folded into the automatic newborn screening panel that every baby receives.\n\nEvidence 1: Standard newborn screening tests a heel-prick blood sample for a set list of conditions, and the panel was built mostly around disorders that can be treated early, such as PKU, where starting a special diet in the first weeks prevents brain damage.\n\nEvidence 2: A result for an adult-onset condition with no childhood treatment does not change the infant's care now, but it creates lifelong knowledge about that person's future body that the newborn cannot yet weigh, and that some people later say they would have chosen not to learn.\n\nReasoning: Because the automatic panel earns its automatic status by catching problems that early action can fix, adding a test that changes nothing in childhood breaks that logic and hands a child a permanent result they never agreed to receive. Offering the screen as a clearly separate choice keeps the medical benefit available for families who want it while protecting the future adult's right to decide what to know about their own body.\n\nReflection: At first I assumed more information at birth is always better, so screening for everything seemed obviously good. Thinking about the difference between a result you can act on now and a result the child will carry for decades made me see that timing and consent matter, not just the test's accuracy. I kept my claim that the screen should exist, but moved it out of the automatic panel and into an informed, opt-in choice.

Also due today: Post your CER and reflection to the PLTW course shell before the end of the block.
