Physiology sensor lab
Fri, Mar 5, 2027 · Week 7 · Biotechnology for Health (Biomedical Innovations)
Today's goal: Collect physiological data using sensors under controlled conditions.
What a finished product looks like
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 |
Also due today: Submit your raw data table to the Schoology lab assignment before leaving the lab area.
