Synthesize all evidence
Mon, Oct 5, 2026 · Week 7 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Organize scene, lab, suspect, and autopsy evidence and plan the PLTW open-investigation report.
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.
Evidence planning (Investigator A-12), practice case (a fall on a wet stairwell, not Case A or Case B):
I rated reliability higher where the collection was controlled, the chain of custody was unbroken, and controls were used. The autopsy and lab streams rated high; the suspect-information stream rated lower because it relied on a single statement.
Your sheet uses your own case's exhibits; copy the shape, not the words.
| Stream | Items I have | Reliability | Key limitation |
|---|---|---|---|
| Scene | Stairwell photos, broken handrail, wet-floor sketch | High | Photos taken after the scene had been walked through |
| Lab | Toxicology screen (negative) | High | Covers only the substances tested |
| Autopsy | Skull fracture with bleeding under it | High | Cannot tell a fall from a push |
| Suspect | One statement | Low | Single, unverified source |
This model shows the level of evidence and organization needed to complete: A four-column planning sheet listing each evidence stream, the specific items in it, a reliability rating, and the key limitation, used to plan the investigation report.
- 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.

Claim ceiling: Today's evidence supports a classroom claim about synthesize all evidence. It cannot prove causation, diagnose a real patient, or justify action outside this room.
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.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Judging evidence reliability for synthesis.
- 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.
