What to do if absent- CER:
- Claim, Evidence, Reasoning: make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure, the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities. Find it in Clever with your Microsoft sign-in, right next to Schoology.
Turn a messy set of patient symptoms into an organized outbreak investigation an epidemiologist could act on.
- 1List the cases. From the patient data your teacher provides, list each patient with their symptoms and onset date.
- 2Separate signs from symptoms. Sort each observation into a SIGN (measurable, e.g., fever 39°C) or a SYMPTOM (reported, e.g., 'feels tired').
- 3Cluster. Group patients who share symptom patterns. Note anything they have in common (place, food, contact).
- 4Map relationships. Draw who-contacted-whom and mark likely a reservoir or vector if one appears.
- 5Hypothesize. Write a CER: claim (what kind of ), evidence (your clusters), reasoning (why the pattern fits).
- • 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.
Open any day for its full lesson, the work due that day, and guided notes.

Do this: Advance the PLTW Unit 1 infection case: build the outbreak map and record your initial diagnosis hypothesis as evidence.
- • The difference between a sign and a symptom.
- • How epidemiologists use line lists and relationship maps.
- • categories (bacteria, virus, fungus, parasite).
- • Organize raw case data into a usable map.
- • Write a CER that proposes a category from evidence.

Fiction. There is no such student. The lessons, labs and dates are the real planned course; the student, the classmates and the conversations are invented.
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.

You can't do those from home: do this instead: CDC-style from teacher data.
