The story

What did this day actually feel like?

Kinesiology data analysis

Graph of force or angle against trial number, then a CER claiming what the trend shows about fatigue.

My prediction from Tuesday was directionally right and wrong about the shape. The decline was not steady, it dropped fast and then leveled off. Being wrong in a specific way is much more useful than being vaguely right.

AT HOME, THE NIGHT BEFORE WED MAR 3 Submit motion-data evidence Raw table, labeled graph, fatigue CER, and a limitations line about the sensor placement problem.

🛠 Get unstuck · pick your level

Need a running start
Before graphing, get two terms clear: kinesiology is the study of human movement, and range of motion (ROM) is how far a joint moves, measured in degrees. Your graph is about to show ROM changing.
On track
Graph your data, name where the slope declines, then write a CER whose evidence quotes actual trial numbers ('ROM fell from 82 degrees at trial 3 to 61 degrees at trial 9'), because the slope of that decline is your fatigue rate.
Stuck? Get unstuck
Absent? Use the class sample data set to build the graph and practice writing one CER sentence that cites two specific trial values as evidence.
Push me further
Calculate the actual slope of your decline (change in angle divided by change in trials) and argue whether that fatigue rate would matter for a real task like a warehouse worker's repeated lift.

Mr. Mendoza's 5-minute intro
  • Yesterday you collected raw numbers. Today you turn them into a story.
  • First you graph. Force or angle on the Y-axis, trial number on the X-axis. A proper graph has a title, labeled axes with units, and a scale that uses the full space.
  • Then you write a CER. Your claim names what happened to . Your evidence cites specific trial numbers from your table. Your reasoning connects the data to the physiology of fatigue.
  • A vague CER gets no credit. Use your numbers.
Know by the end
  • A line graph of force or angle versus trial number should show a plateau or decline as fatigue sets in; the slope of that decline quantifies fatigue rate.
  • is the study of human movement; (ROM) is the extent of movement at a measured in degrees.
  • A CER using collected data must cite specific trial numbers or values as evidence, not general statements about what usually happens.

Learn it · deck, reading, and vocabulary
Socratic teaching slide deck

The deck carries the prior idea forward, lets you inspect an analogy, maps the rule to biology, and ends with the same evidence decision and exit ticket used on this page.

Generated from this lesson's canonical data with a red-team citation check.

Carry forward

A conclusion is only as good as the data under it, so you zero your sensor and run consistent trials in order to tell a real fatigue trend apart from a single noisy reading.

Daily take-home

Graphing physiological data reveals a trend the raw table hides, so a CER that cites your specific trial values proves fatigue changed , while a general statement proves nothing.

Inspect the analogy

A detective board holds observations, possible explanations, and one next question.

  1. Which notes are direct observations?
  2. Which notes are explanations?
  3. What new evidence would separate the explanations?
Rule

Keep observations separate from explanations, then collect the evidence that can distinguish the options.

Where it breaks

Biomedical investigations use controlled procedures and validated measurements, not intuition alone.

Map the analogy to biology
  • Board notes map to E1-E3.
  • Possible explanations map to the decision options.
  • The next question maps to the evidence-based action.
Read this first

Driving question: Your has 12 numbers in it. How does graphing them show you the exact moment fatigue changed your , and how steep that change was?

What you already know: A conclusion is only as good as the data under it, so you zero your sensor and run consistent trials in order to tell a real fatigue trend apart from a single noisy reading.

New idea: Graphing physiological data reveals a trend the raw table hides, so a CER that cites your specific trial values proves fatigue changed , while a general statement proves nothing.

Visual or model: F1. F1. A lesson illustration or teaching diagram for Kinesiology data analysis. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Trace the labeled structure, movement, or system relationship that connects form to function.

  1. Observe or measure the relevant feature in data analysis.
  2. Organize the observation with a stable evidence ID.
  3. Apply this rule: Keep observations separate from explanations, then collect the evidence that can distinguish the options.
  4. Choose the option the evidence supports and state the limit of the conclusion.

Real biomedical example: Your has 12 numbers in it. How does graphing them show you the exact moment fatigue changed your , and how steep that change was?

What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.

What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.

Vocabulary:
  • fatigue: A state of physical or mental tiredness in which muscles or the body produce less force or focus and need rest to recover.
  • EMG: Electromyography, a test that records the electrical signals muscles produce when they contract, used to study muscle and nerve function.
  • : The full distance and direction a can move, measured in degrees from its fully bent to its fully straightened position.
  • : Bending a so the angle between two body parts decreases, such as curling the forearm toward the shoulder.
  • extension: A movement that increases the angle of a and straightens a body part, such as opening the arm to straighten the elbow.
  • biomechanics: The study of how forces, motion, and structure act on living bodies, applying physics to muscles, bones, and joints.
  • : The scientific study of human movement, including how muscles, bones, and the nervous system work together to produce motion.

Use it now: Choose one decision option. Cite E1 and E3, then explain how the rule connects the evidence to your choice.

Go further, optional: The source links below are optional enrichment. Every fact required for today's local evidence decision appears in this lesson package.

Evidence set and decision
E1 · Observation

A line graph of force or angle versus trial number should show a plateau or decline as fatigue sets in; the slope of that decline quantifies fatigue rate.

Limit: E1 supplies context or an observation; it does not by itself establish the explanation.

E2 · Mechanism

Graphing physiological data reveals a trend the raw table hides, so a CER that cites your specific trial values proves fatigue changed , while a general statement proves nothing.

Limit: E2 is a teaching statement or comparison and must be checked against the task evidence.

E3 · Result

You can graph and describe a fatigue trend.

Limit: E3 supports only the result or product criterion named here; it cannot justify a broader clinical or causal claim.

PLTW-HAP-2027-03-02 · Simulated classroom evidence scenario

Your role: anatomy and physiology consultant

Decision: Your team must decide what the evidence from data analysis supports before submitting the claim-evidence-reasoning response named on the lesson page.

  • Select the option best supported by E1-E3.
  • Select a reasonable alternative and name the evidence it would require.
  • Delay the claim because the evidence does not distinguish the options.

Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the claim-evidence-reasoning response.

Claim ceiling: The supplied lesson evidence can support an observation, pattern, classroom mechanism, or next-step decision about data analysis. It cannot by itself prove causation, establish a real clinical diagnosis, or justify action outside this classroom task.

Math moment
Formula or setup

Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.

Worked parallel example

For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.

Units and reasonableness

Mean, median, and range keep the measurement unit. Order the values before finding the median.

Try it with today's data

Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.

Watch the trap

Students often think Students write a CER that says fatigue 'usually lowers performance' and think that counts as evidence.. The trap: General statements about what normally happens are not evidence, because a data-based CER has to cite YOUR specific trial numbers or values, otherwise you are quoting common sense instead of your experiment.

Worked example · a parallel case (guides, does not reveal)
Worked CER on a parallel case (grip-strength fatigue), modeling the graph plus claim-evidence-reasoning format without answering today's elbow range-of-motion prompt
Completes: A labeled graph of a measured variable versus trial number, plus a claim-evidence-reasoning argument that cites specific data values to explain how fatigue changed performance across repeated trials.

Parallel scenario (not today's task): A test subject squeezed a hand dynamometer as hard as possible once every five seconds for eight trials while the grip force in kilograms was recorded. The question was whether fatigue changed the force output, when the change began, and how steep it was.\n\nGraph: a line graph with grip force (kilograms) on the y-axis and trial number on the x-axis, showing a flat plateau for the first few trials followed by a clear downward slope.\n\nClaim: Muscle fatigue reduced grip force output over the repeated squeezing trials.\n\nEvidence: The force stayed close to 44 kilograms for trials 1 through 3, then dropped to 40 kilograms at trial 4 and continued falling to 31 kilograms by trial 8, a total decline of about 13 kilograms. The steepest single drop, about 5 kilograms, happened between trial 4 and trial 5.\n\nReasoning: One low reading by itself could just be a bad squeeze or a measurement slip, but the steady downward slope from trial 4 onward shows a real trend rather than random error. As the muscle repeatedly contracted, its stores of ATP and phosphocreatine ran low and metabolic byproducts built up, so the fibers could no longer generate the same peak force. The graph pins the change to trial 4, where the plateau ends and the line begins to fall, and the sharp segment between trials 4 and 5 shows that is where fatigue set in fastest. This is why turning the numbers into a graph, instead of just reading the table, makes the exact moment and steepness of the change visible.

Line graph of joint angle versus trial number: nearly flat for the first three trials, then a steady downward slope from trial four onward marking fatigue onset.
Why this matters

This model shows the level of evidence and organization needed to complete: A labeled graph of a measured variable versus trial number, plus a claim-evidence-reasoning argument that cites specific data values to explain how fatigue changed performance across repeated trials.

Build yours step by step
  1. Write one defensible claim.
