Why these are optional: the WebXam weighs them least, so they move here to keep every tested unit in class. Doing them is a real way to go deeper and earn extra credit, never a penalty if you skip them.

Optional extra-credit units

These units are not on the in-class calendar or any in-class test. They unlock once the class finishes Unit 2, then stay open for the rest of the term so you can go further for extra credit on your own schedule. You will know they are open when an Extra Credit section appears at the bottom of your daily lesson pages. Every hands-on step has a virtual lab.

Debate exit ticket
Completes: Completes the device innovation ethics debate exit task: one sentence naming the strongest opposing testing argument the student encountered.

I argued for extended testing before release. The strongest opposing argument I heard was that for a patient who is dying now, a long testing timeline can be a death sentence, so rapid access to a promising device may be the more ethical choice even with some added risk.

(Tip: state the opposing point fairly in one sentence using design vocabulary like prototype, iteration, or disease prevention. Stating the strongest version of the other side is what earns full marks.)

Annotated engineering design notes
Completes: Completes the engineering design note-taking task: the seven labeled design stages, a CAD description, an iteration worked example, and a disease-prevention connection.

Engineering design process (seven stages, in order):

  • Define the problem: state exactly what need the device must meet.
  • Research: gather what is already known.
  • Brainstorm: generate many possible solutions.
  • Prototype: build an early testable model.
  • Test: collect data on how it performs.
  • Evaluate: compare the data to the design goal.
  • Iterate: redesign based on the data, then test again.

CAD (computer-aided design):

  • CAD turns a concept sketch into a precise digital model with real measurements, so it can be tested or 3D printed exactly to specification.

Iteration worked example:

  • A filter device let 8 mL/min through; the goal was 12 mL/min. We changed only the pore size (one variable) and predicted a higher flow. Next trial measured 11 mL/min, closer to goal. Changing one variable at a time told us the pore size caused the change.

Disease-prevention connection:

  • The design criteria come from the prevention goal: a device meant to filter a contaminant must be specified to remove that contaminant, because you cannot test what you did not specify.

Device testing data table
Completes: Completes the testing lab: a data table with at least three trials, labeled variables, an average, one measurement-error source, and one setup limitation.

SOP recorded: assemble the model to spec, run the same test three times, record each result, then average.

Variables:

  • Independent variable: pore size of the filter (what we deliberately changed between designs).
  • Dependent variable: flow rate in mL/min (what we measured).
  • Controlled variables: same liquid, same volume, same temperature, same timer, held constant across all trials.

Design goal: flow rate of at least 12 mL/min.

Results: Trial 1 = 11.0, Trial 2 = 11.6, Trial 3 = 11.3 mL/min. Average = (11.0 + 11.6 + 11.3) / 3 = 11.3 mL/min.

Measurement error source: the stopwatch was started by hand, so reaction time could add or subtract a fraction of a second each trial. That is a tool-and-technique error, named at the source, not just 'human error.'

Test-setup limitation: we ran only three trials, so an unusual single result would pull the average noticeably. More trials would make the average more trustworthy.

A model of the work to turn in. Match its structure and level of detail; do not copy it. Your data and wording should be your own.

Prototype evaluation CER
Completes: Completes the prototype argument: a CER stating whether the device met its goal, citing averaged trial data, proposing a specific iteration with a predicted result, and stating limitations.

Claim: The prototype did not fully meet its design goal. The goal was a flow rate of at least 12 mL/min, and the prototype averaged 11.3 mL/min.

Evidence: Across three trials the flow rates were 11.0, 11.6, and 11.3 mL/min, for an average of 11.3. Variability was small (a 0.6 mL/min spread), so the result is consistent, just below target. Controlled variables (liquid, volume, temperature) were held constant, so pore size was the cause of the flow rate.

Reasoning: A consistent 11.3 average that sits below the 12 goal tells us the design is close but the pore size is slightly too restrictive. The low trial-to-trial spread means the shortfall is real, not random noise.

Iteration proposal (one variable): increase the pore size by one step, holding everything else constant. Prediction: flow rate should rise above 12 mL/min, likely around 12 to 13, because a larger pore lets more liquid through per minute.

Assumptions and limitations: Only three trials were run, so the average could shift with more data. The hand-started stopwatch adds small timing error. Both are reasons to re-test after the iteration rather than assume success.

Two frontier biomedical challenges and their Earth parallels:

  • Space: microgravity causes rapid bone-density and muscle loss. Earth parallel: the same countermeasures inform osteoporosis and bed-rest muscle-wasting treatments.
  • Undersea / hyperbaric: high-pressure environments risk decompression injury and oxygen toxicity. Earth parallel: hyperbaric oxygen therapy is now used to heal chronic wounds and treat carbon-monoxide poisoning.

What a GIS story-map communicates:

  • A GIS story-map layers health data onto a map so you can see WHERE events happen, not just how many. Components I will use: a base map, a data layer (cases or exposure points by location), a legend, and short narrative text panels that walk the reader through the pattern.

Four-component innovation pitch outline:

  • Problem: the specific health need, stated with a number.
  • Solution: the innovation and how it works.
  • Evidence: data from prior units and the story-map that support it.
  • Next step and limits: what to develop or test next, and what is still unknown.

Earth application in one line: frontier constraints force efficient, portable designs, and portable diagnostics built for a submarine or capsule also serve rural clinics with no lab.

SOP and member responsibilities:

  • Workflow: define problem, synthesize evidence, build story-map, draft pitch, then review against the rubric. Roles: Maria (story-map), Devon (evidence synthesis), Priya (CER draft), me (problem definition and tracker).

Health problem (with a number): In our target neighborhood, an estimated 1 in 4 households lacks quick access to a clinic for early infection screening, delaying diagnosis.

Synthesis evidence from two prior units:

  • From the Infection unit: rapid antigen screening catches disease earlier, which lowers spread.
  • From the Outbreak unit: mapping case locations reveals clusters where screening should be placed first.

Innovation concept: a portable, low-cost screening kit paired with a GIS story-map that routes it to the highest-cluster blocks first.

Draft story-map (two layers): Layer 1, a base map of the neighborhood; Layer 2, screening-access points colored by household distance to the nearest clinic.

Pitch-section assignments: problem (me), solution and story-map (Maria), evidence (Devon), CER and next steps (Priya).

Innovation pitch CER
Completes: Completes the synthesis argument: a CER naming the problem and innovation, citing evidence from two prior units and the story-map, explaining disease-prevention reasoning, recommending a next step, and stating limits.

Claim: A portable early-screening kit, routed by a GIS story-map to the highest-need blocks, would reduce delayed infection diagnoses in our target neighborhood.

Evidence: From the Infection unit, rapid antigen screening detects disease earlier and lowers onward spread. From the Outbreak unit, mapping case locations shows that cases cluster, so screening is not needed evenly everywhere. Our story-map's access layer shows that a quarter of households sit farthest from a clinic and overlap the historical clusters.

Reasoning: Earlier detection prevents disease by interrupting spread before an outbreak grows. Because the evidence shows both that early screening helps and that need is geographically uneven, routing a portable kit to the highest-cluster, lowest-access blocks should catch cases sooner than spreading the same resource evenly. The two units support different halves of the claim, and the story-map ties them to a place.

Recommended next step: build one kit prototype and pilot it on the two highest-cluster blocks, measuring time-to-diagnosis against a clinic-only baseline.

Assumptions and limitations: we assume the historical clusters still hold and that households will use a nearby kit; both need checking in the pilot. Our access data came from one source, so the estimate may be off. These are reasons to pilot and re-measure, not to deploy citywide yet.

Why this matters

This model shows the level of evidence and organization needed to complete: Completes the synthesis argument: a CER naming the problem and innovation, citing evidence from two prior units and the story-map, explaining disease-prevention reasoning, recommending a next step, and stating limits.

Build yours step by step
  1. Write one defensible claim.
  2. Choose specific evidence that supports the claim.
  3. Explain the scientific rule that connects the evidence to the claim.
Change it for a new task

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 CER on the class site, or hand it to Mr. Mendoza in class before end of period.

#10FridaySubmit tracker and pitch

🎯 Students finalize and submit the final medical-innovation pitch package and update the tracker.

  1. 1Compile the story-map, pitch, and CER into one labeled package.
  2. 2Check the package against the rubric for completeness and vocabulary.
  3. 3Cite all sources and note unresolved limitations.
  4. 4Update the project tracker with final status and a confidence rating.
  5. 5Submit the innovation pitch package through the course portal on time.
You'll be able to
  • Submit a complete, rubric-aligned pitch package on time.
  • Tracker reflects accurate final status and a limitations note.
Submit for extra credit

Turn this in at the drop folder with your district Microsoft sign-in, or hand it to Mr. Mendoza in class. Both count as submitted. Doing the activity in myPLTW does not.

Completing all five days of this reserve unit earns extra credit points applied to your current unit grade; partial completion earns proportional credit.

Capstone tracker update
Completes: Completes the capstone closeout: a tracker with final PBS status, per-unit confidence ratings, one reflection note, and the linked four-artifact innovation package.

Project tracker, PBS Innovation capstone:

  • Status: Complete. Four labeled artifacts attached: the draft GIS story-map, the innovation pitch, the pitch CER, and this tracker.
  • Confidence ratings across the course:

- Forensics and evidence (Units 1 to 2): 88 percent.

- Clinical data and diagnostics (Unit 3): 82 percent.

- DNA, protein, and genetic risk: 79 percent.

- Infection, outbreak, and this innovation synthesis: 90 percent.

  • Capstone reflection: My strongest synthesis was tying outbreak mapping to infection screening; my weakest spot is genetic-risk vocabulary, which is my WebXam review target.
  • Sources cited: the two prior-unit datasets, the public access data, and the design brief. All real and attached, no placeholders.
  • Unresolved limitation: the access estimate uses one source and needs a second before any real deployment.

Rating genetic risk at 79 percent instead of rounding up is the useful move: it tells me exactly what to study before the exam.
