Week overview - Matching for Life: Organ Transplant and Dialysis

Dec 14–18

Use a compatibility dataset and a or matching simulation to recommend a transplant match and explain risk.

Week arc
  1. 1Open the compatibility dataset in the PLTW course shell and read the blood-type and key before matching anyone.
  2. 2Put on goggles and gloves, then run the or matching simulation following the station protocol.
  3. 3For one recipient, list compatible donors by blood type and circle the closest match.
  4. 4Write one sentence explaining how a normally filters blood and what replaces.
  5. 5Recommend a donor for your recipient and back it with evidence using the words and .
  6. 6Add one question for the Monday allocation debate about how organs should be prioritized among patients.
By week end
  • • You'll be able to explain how replaces failing kidney function.
  • • You'll be able to use blood type and data to find a transplant match.
  • • You'll be able to connect a result to risk.

Daily lessons this week

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

MondayMon, Dec 14
Allocation debate

Written final stance on kidney allocation priority, with a one-sentence reason and a one-sentence rebuttal to the competing stakeholder.

TuesdayTue, Dec 15
Dialysis and matching simulation

Simulation : waste-level time series, each donor-recipient pair's match count and result (positive or negative), and -risk flags with explanations.

WednesdayWed, Dec 16
Compatibility and rejection

Compatibility table ranking donors by match score, plus a written immune- explanation and benefit/risk note.

ThursdayThu, Dec 17
Allocation CER

Allocation CER recommending a specific patient for a donor kidney, citing the result and urgency data, with reasoning explaining why competing evidence is outweighed.

FridayFri, Dec 18
Emerging-tech debate

Written final stance on emerging-intervention pursuit and governance, with a one-sentence reason and a one-sentence rebuttal to the opposing argument.

Get oriented

Quick intro to the week

  • Today matters because a single good match can give someone years of life, and a bad one can fail fast.
  • Goal for today: use real-style compatibility data to recommend a match and explain why it should hold.
  • Monday's debate is allocation: with more patients than organs, how should the waiting list be ordered?
  • Your matching recommendation and dataset work are graded in the PLTW course shell, so finalize them there.
Do the work

Your PLTW coursework this week

Do this: Advance the Unit 4 organ-transplant benchmark by submitting your data-backed donor match recommendation on the class site.

Know when done
  • • The is the kidney's filtering unit, and takes over filtering when kidneys fail.
  • • Blood type and matching reduce the chance of transplant .
  • • A checks whether a recipient's immune system reacts to a specific donor.
Be able to do
  • • Use compatibility data to identify a transplant match.
  • • Explain how a result relates to risk.

📋 Tracker evidence due this week: your compatibility dataset analysis and donor match recommendation submitted on 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

Sign in to Clever with your district Microsoft account to open Schoology or myPLTW. Follow today's posted steps. If myPLTW will not open, use the posted alternative and tell Mr. Mendoza. Turn in your completed work through the Schoology assignment.

Was today a lab or a group activity?

You can't do those from home: do this instead: Compatibility dataset.

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:
