Week overview - Editing the Code: Gene Therapy and Its Ethics

Oct 26–29

Use a article to build a claim-evidence-reasoning argument about whether or should be allowed for a given case.

Week arc
  1. 1Open the article in the PLTW course shell and annotate where it explains vectors and Cas9.
  2. 2In your notes, define versus in one sentence each.
  3. 3Circle one place in the article that mentions effects and note why that worries scientists.
  4. 4Write a claim stating whether the case should use or .
  5. 5Add two pieces of evidence from the article that support your claim, including .
  6. 6Finish your CER with reasoning that connects the evidence to your claim in two sentences.
By week end
  • You'll be able to tell from .
  • You'll be able to explain what a viral vector and do.
  • You'll be able to write a CER argument grounded in an article.
The plan

Daily lessons this week

Open any day for its full lesson, the work due that day, and guided notes.

MondayMon, Oct 26
Germline editing debate

One CER on whether gene editing should ever be permitted, plus a reflection naming one counterargument about consent of future generations.

TuesdayTue, Oct 27
Viral vector chart

Viral vector delivery diagram with labeled components, vs. distinction, two-vector comparison row, and one sentence on vector-cell targeting.

WednesdayWed, Oct 28
CRISPR and reproductive screening

Annotated article (guide RNA, Cas9 cut, repair step marked; defined) plus a CER on using CRISPR in the reproductive screening case.

ThursdayThu, Oct 29
Gene therapy ethics CER

Complete ethics CER: claim on whether the case patient should receive therapy, two evidences from vector chart and work, reasoning naming one risk.

Get oriented

Quick intro to the week

  • Today matters because is moving from science fiction to clinics, and you get to weigh in.
  • Goal for today: read a article closely and turn it into a clear claim-evidence-reasoning argument.
  • Monday's debate is : should we make changes that pass to a person's children and beyond?
  • Your annotations and CER are graded from what you turn in, so submit them on the class site.
Do the work

Your PLTW coursework this week

Do this: Advance the Unit 2 gene-therapy benchmark by submitting your -article CER on the class site.

Know when done
  • delivers corrected genes, often using a viral vector.
  • edits affect one patient while edits pass to descendants.
  • can cut DNA at a target, but effects are a real risk.
Be able to do
  • Distinguish from .
  • Build a CER argument from an article with evidence and reasoning.

📋 Tracker evidence due this week: your annotated article and completed CER argument uploaded to the class site.

All PLTW activities are completed inside the PLTW course environment: this page only gives direction.

What to do when absent

If YOU are absent

Most days, this class is your PLTW coursework: and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.

Open Clever, then myPLTW

How to get there: open Clever and sign in with your Microsoft (district) account. Both myPLTW and Schoology are in Clever. Do the activity in myPLTW. Turn the work in on this site or hand it to Mr. Mendoza, because that is the step that counts as submitted. Schoology only shows your report-card grade later.

Was today a lab or a group activity?

You can't do those from home: do this instead: article annotation and CER.

If MR. MENDOZA is absent

Class still runs. A substitute will post today's plan: complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
