Investigating an outbreak: explain and revise
Thu, Sep 10, 2026 · Week 3 · Genetics of Disease (Medical Interventions)
Today's goal: Discuss and revise your Day 1 explanations. Write a claim, evidence, and reasoning (CER) response and finish the Activity 1.1.2 conclusions.
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.
MR1 reports a cough and runny nose. MR2 says symptoms began gradually. MR3 supplies no laboratory result. R1 and R2 show that these clues can fit a cold or COVID-19. The evidence supports comparing causes, not confirming one. An appropriate laboratory result could help distinguish possibilities.
| Record | Fact | Limit |
|---|---|---|
| MR1 | Cough and runny nose reported | Symptoms overlap between illnesses |
| MR2 | Gradual onset | Timing alone does not confirm the cause |
| MR3 | No laboratory result supplied | Unknown is not a negative result |
This model shows the level of evidence and organization needed to complete: Original simulated practice for the research and explanation work in Activity 1.1.2. It contains no official case answers.
- Date and label the entry.
- Record the procedure, observation, or design decision clearly.
- End with what the evidence means and the next step.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Use the official histories and the research library for your own work. Keep Model R separate from official evidence.
Turn in: Model R: compare possibilities and name a limit

Claim ceiling: Explain a tentative connection with three cited evidence points and a limit. Day 1 evidence cannot confirm a pathogen or a source; a possible explanation is not a diagnosis.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

It builds this reusable test skill: Using source evidence to evaluate a hypothesis.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
