Physiology sensor lab
Thu, Mar 4, 2027 · Week 7 · Biotechnology for Health (Biomedical Innovations)
Today's goal: Collect physiological data using sensors under controlled conditions.
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.
Research question: Does light activity raise resting heart rate?
Sensor: pulse/heart-rate sensor, calibrated against a 60-second manual pulse count before trial 1.
Conditions controlled: same subject (Subject A), seated for baseline, same room temperature, 2-minute rest between trials.
I recorded five repeated trials for each condition and logged every reading separately rather than averaging in my head:
- Baseline (resting), trials 1-5: 72, 70, 74, 71, 73 bpm
- Treatment (after 1 min stepping), trials 1-5: 96, 99, 94, 101, 98 bpm
Condition-control note: I kept the subject, sensor placement, and rest interval the same across all trials so that the only thing changing was rest vs light activity. That is what lets me trust a difference if I find one.
| Trial | Condition | Heart rate (bpm) |
|---|---|---|
| 1 | Baseline rest | 72 |
| 2 | Baseline rest | 70 |
| 3 | After stepping | 96 |
| 4 | After stepping | 99 |
| 5 | After stepping | 94 |
This model shows the level of evidence and organization needed to complete: Completes the Problem 2 sensor-lab data-collection step: a structured raw data table of repeated, controlled physiology trials ready for analysis.
- Name the variables and include units.
- Enter observations without changing the raw values.
- Check labels, calculations, and patterns before interpreting the data.
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: Submit your raw data table on Schoology before leaving the lab area.

Claim ceiling: Today's evidence supports a classroom claim about physiology sensor lab. 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: Following a sensor SOP: calibration and repeated controlled trials.
- 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.
