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 screening blood-spot storage)
Completes: Worked CER on a parallel case: a claim about whether the state should keep leftover newborn screening blood spots for later research, two pieces of evidence, reasoning, and a reflection naming one counterargument. Models the CER format and depth for the access-to-results debate without answering today's own prompt about raw genetic results.

Claim: States should be allowed to store leftover newborn screening blood spots for future research, but only if parents are clearly told and can opt out.\n\nEvidence 1: Every newborn is screened for genetic disorders using a heel-stick blood spot, and the leftover cards contain a child's DNA, which can reveal far more than the original tests checked for.\n\nEvidence 2: In Texas in 2009, a lawsuit revealed that stored newborn blood spots had been used for research without parents' knowledge, and the state was ordered to destroy millions of samples, showing that hidden storage breaks public trust.\n\nReasoning: Stored blood spots are genuinely useful for studying diseases and improving future screening, so destroying them all wastes a resource that could help other children. But the DNA belongs to the child and the family, not the state, and using it in secret treats people as sources of data rather than as patients. Requiring clear notice and an opt-out respects the family's ownership of the sample while still allowing research that benefits the public.\n\nReflection: One counterargument is that an opt-out will shrink the sample pool and slow research, since many families will decline once they are asked. I took that seriously, but I kept my claim, because trust is what keeps the whole screening program running. If families fear their child's DNA is used behind their backs, they may resist screening itself, and the public-health cost of that distrust is higher than the cost of a smaller research pool.

Also due today: Post your CER and reflection to the PLTW course shell.
