Week overview - Framing an Outbreak Investigation

Sep 8–11

Turn a messy set of patient symptoms into an organized outbreak investigation an epidemiologist could act on.

Week arc
  1. 1List the cases. From the patient data your teacher provides, list each patient with their symptoms and onset date.
  2. 2Separate signs from symptoms. Sort each observation into a SIGN (measurable, e.g., fever 39°C) or a SYMPTOM (reported, e.g., 'feels tired').
  3. 3Cluster. Group patients who share symptom patterns. Note anything they have in common (place, food, contact).
  4. 4Map relationships. Draw who-contacted-whom and mark likely a reservoir or vector if one appears.
  5. 5Hypothesize. Write a CER: claim (what kind of ), evidence (your clusters), reasoning (why the pattern fits).
By week end
  • Distinguish signs from symptoms in real patient data.
  • Build a relationship/line-list map from raw cases.
  • State a defensible first diagnosis hypothesis with evidence.

Get oriented

Quick intro to the week

  • Monday is a Philosophy-for-Kids bioethics debate: vs. autonomy: how much can limit one person's freedom to protect many?
  • Bring two prepared questions and one CER contribution.
  • By Friday you owe an outbreak relationship map + a CER diagnosis hypothesis.
Do the work

Your PLTW coursework this week

Do this: Advance the PLTW Unit 1 infection case: build the outbreak map and record your initial diagnosis hypothesis as evidence.

Know when done
  • The difference between a sign and a symptom.
  • How epidemiologists use line lists and relationship maps.
  • categories (bacteria, virus, fungus, parasite).
Be able to do
  • Organize raw case data into a usable map.
  • Write a CER that proposes a category from evidence.

📋 PLTW evidence to log: outbreak relationship map and CER diagnosis hypothesis for the Unit 1 infection case.

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: CDC-style from teacher data.

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:
