What to do if absent- CER:
- Claim, Evidence, Reasoning: make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure, the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities. Find it in Clever with your Microsoft sign-in, right next to Schoology.
Week overview - Motion Data: muscle strength, fatigue, and range of motion
Collect muscle strength, fatigue, and range-of-motion data with sensors, and analyze how and extension relate to biomechanics and .
- 1Set up the physiology sensor and zero it before collecting any muscle data.
- 2Record a muscle effort over time and watch for the point where fatigue begins.
- 3Measure at a during and extension and log the angles.
- 4Build a simple table comparing your data before and after repeated effort.
- 5Connect one taping idea to a your data shows is weak or fatigued.
- 6Write a short claim about how fatigue changed your strength or , supported by your data.
- • You will be able to collect muscle strength or fatigue data with a sensor.
- • You will be able to measure during and extension.
- • You will be able to make an evidence-based claim about muscle fatigue from your data.
Daily lessons this week
Open any day for its full lesson, the work due that day, and guided notes.
One-paragraph CER taking a position on whether employers should access wearable physiological data from workers.
Labeled prediction sketch of an EMG trace across repeated trials showing fatigue onset, plus a written fatigue-mechanism summary.
Raw with trial number, measured value (mV or degrees, with units), time, and fatigue-onset trial clearly marked.
Labeled graph of force or angle versus trial number plus a CER claiming how fatigue affected , citing specific data values.
Complete motion-data evidence packet: raw , labeled graph, fatigue CER, and two-sentence reflection.
Quick intro to the week
- Hook: physical therapists use the same kind of sensors you will today to track how a patient is recovering.
- Today's goal: turn your own muscle effort into data and read what fatigue and are telling you.
- Monday bioethics tie-in: should schools require fitness testing, and who should be allowed to see those results?
- Reminder: your graded fatigue or ROM data report is submitted on the class site.
Your PLTW coursework this week
Do this: Advance the PLTW HBS online benchmark through Unit 1.2 Motion Data.
- • Muscle fatigue is the drop in force a muscle can produce after repeated effort.
- • describes how far a moves through and extension.
- • Collect muscle strength or fatigue data with a physiology sensor.
- • Measure and interpret at a .
📋 PLTW evidence due this week: your muscle fatigue or range-of-motion data report with an evidence-based claim.
All PLTW activities are completed inside the PLTW course environment: this page only gives direction.

Lab day: what to bring & watch
This explainer accompanies the PLTW lab protocol: watch it before lab.
What to do when absent
Most days, this class is your PLTW coursework: and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.
Open Clever, then myPLTWHow to get there: open Clever and sign in with your Microsoft (district) account. Both myPLTW and Schoology are in Clever. Do the activity in myPLTW. Turn the work in on this site or hand it to Mr. Mendoza, because that is the step that counts as submitted. Schoology only shows your report-card grade later.
You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: joints and movement; Vernier/Logger Pro reference if local.
Class still runs. A substitute will post today's plan: complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
