💡 Big idea: Collecting accurate physiological data requires correct sensor setup, consistent trial protocol, and careful unit recording before analysis can begin.

  1. 0-10Safety and sensor setup; zero baseline and practice trial
  2. 10-20Protocol review: number of trials, rest intervals, recording format
  3. 20-50Run trials; record force or angle and time in data table
  4. 50-62Mark fatigue-onset trial; add qualitative observations column
  5. 62-75Peer-check: does each row have units? Is fatigue-onset trial marked?
  6. 75-80Submit raw data table; clean up sensors
Mr. Mendoza's 5-minute intro
  • • Today is a sensor lab. You are collecting real data from real muscles.
  • • The protocol is simple: set up, zero the sensor, run trials, record everything. But the discipline of recording every trial with units is what makes this science.
  • • Your data table today is raw evidence. Do not average or analyze yet. Thursday is for analysis.
  • • Mark the trial where you first see a consistent drop. That is your fatigue-onset marker.
Do this, step by step
  1. 1Set up the EMG sensor or goniometer and zero the baseline.
  2. 2Run repeated trials of a grip or joint movement until fatigue appears.
  3. 3Record force or angle and time for each trial in your data table.
  4. 4Note the trial where performance clearly dropped.
  5. 5Submit your raw data table with units and the fatigue-onset trial marked.
You'll be able to
  • • You can collect clean motion or EMG data with units.
  • • You can identify the trial where fatigue begins.
Know by the end
  • • A goniometer measures joint angle in degrees; EMG sensors measure muscle electrical activity in millivolts. Both require zeroing before data collection.
  • • A data table must include: trial number, measured value (with units), and any qualitative observation (pain, tremor, noticeable fatigue).
  • • Identifying the fatigue-onset trial requires looking for a consistent downward trend in force or angle, not a single low value.

1 · What you do today

🎯 Collect EMG or range-of-motion data and record results in a data table.

  • Set up the EMG sensor or goniometer and zero the baseline.
  • Run repeated trials of a grip or joint movement until fatigue appears.
  • Record force or angle and time for each trial in your data table.
  • Note the trial where performance clearly dropped.
  • Submit your raw data table with units and the fatigue-onset trial marked.

Safety / SOP
  • • Confirm no skin allergies to electrode gel or adhesive before applying EMG electrodes.
  • • Do not apply electrodes over broken skin, rashes, or open wounds.
  • • Stop the trial immediately if a participant reports sharp pain rather than muscle fatigue.
  • • Dispose of single-use electrode pads in regular trash; do not reuse.

What to do if you were absent

Today was a lab — do this instead

Use the linked simulation or the teacher's posted EMG dataset to record trials of a fatiguing movement, build a data table with units, and mark where performance dropped, then submit it.

PhET Simulations

Then submit your Data table on Schoology.
