How this lesson connects
Keep using what you learned last class: Skipping safety testing does not truly speed help, because a failed patient-facing device costs a life rather than money, so the urgency of an innovation never justifies releasing it untested. Today: You must answer questions from your own evidence so that the panel trusts your design is real, because a confident guess that proves wrong destroys credibility instantly.
Optional: listen or watch a unit review▸

- • Today is presentation day for Problem 1.
- • You have built a stakeholder map, a patient-flow diagram, a floor-plan prototype, a revision log, and a full research packet.
- • Now you explain it to someone who was not in the room when you made those decisions.
- • Field every question with evidence -- if someone pushes back, your portfolio is your defense.
- • How to deliver a design presentation that is complete, evidence-based, and stays within the allotted time.
- • How to answer a challenging question by citing your own portfolio evidence rather than guessing.
- • How peer feedback on clarity and persuasiveness improves future presentations.

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.
Skipping testing does not truly speed help, because a failed patient-facing device costs a life rather than money, so the urgency of an innovation never justifies releasing it untested.
You must answer questions from your own evidence so that the panel trusts your design is real, because a confident guess that proves wrong destroys credibility instantly.
A bridge prototype is tested against a load limit, cost limit, and user need before revision.
- Which requirement is a criterion?
- Which limit is a constraint?
- What test result should trigger a redesign?
A design improves when evidence is compared with explicit criteria and constraints.
Biomedical designs also require , ethics, and biological validation beyond a physical prototype test.
- • Bridge requirements map to what the device must do for the body.
- • Load results map to the measurements taken from the prototype.
- • Revision maps to the change those measurements justify.
Driving question: When the panel asks the one question you hoped to avoid about your ER design, can you answer it from your portfolio instead of guessing?
What you already know: Skipping testing does not truly speed help, because a failed patient-facing device costs a life rather than money, so the urgency of an innovation never justifies releasing it untested.
New idea: You must answer questions from your own evidence so that the panel trusts your design is real, because a confident guess that proves wrong destroys credibility instantly.
Visual or model: F1. F1. A lesson illustration or teaching diagram for ER presentation. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Trace the labeled system, test, or design relationship and identify which evidence should trigger revision.
- Observe or measure the relevant feature in ER presentation.
- Organize the observation with a stable evidence ID.
- Apply this rule: A design improves when evidence is compared with explicit criteria and constraints.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: A physiology team prepares a short evidence presentation that links its question, measurement method, graph, result, and limitation without overstating the finding. Source: MedlinePlus.
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.
- • hypothesis: A testable, falsifiable prediction about how variables relate, written so an experiment can support it or prove it wrong.
- • : The one factor a researcher deliberately changes in an experiment to test its effect on the measured outcome.
- • : The outcome a researcher measures in an experiment, which may change in response to the variable being tested.
- • control: The comparison condition that isolates the effect of the variable being tested by keeping everything else the same.
- • : The number of subjects or observations in a study; larger samples give more reliable results and reduce the role of chance.
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.
A biomedical design advances when test evidence is compared with explicit user needs, criteria, constraints, risks, and failure modes, then used to justify a documented revision.
Limit: A classroom prototype, , presentation, or does not establish clinical , effectiveness, manufacturing quality, or regulatory clearance.
A design improves when evidence is compared with explicit criteria and constraints.
Limit: Biomedical designs also require , ethics, and biological validation beyond a physical prototype test.
You can present a complete design and cite the evidence behind each choice.
Limit: E3 defines the classroom product or success criterion. It is not independent scientific evidence and cannot justify a clinical or causal claim.
PLTW-BFH-2027-02-25 · Simulated classroom evidence scenario
Your role: biomedical design team member
Decision: Your team must decide what the evidence from ER presentation supports before submitting the lab report named on today's page.
- • Say you do not have that evidence yet when a question reaches past what your portfolio actually documents.
- • Prepare to answer each panel question straight from your portfolio evidence rather than from memory or a guess.
- • Focus your practice on the slides, since the question period afterward is just a formality you get through.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the lab report.
Claim ceiling: Today's evidence supports a classroom claim about ER presentation. It cannot prove causation, diagnose a real patient, or justify action outside this room.
Reason for review: Your team must decide what the evidence from ER presentation supports before submitting the lab report named on today's page.
Context: The capstone engineering skill is defending your design live with your own evidence, because a solution you cannot explain under pressure is a solution no one can trust to build.
- • T1: Deliver your presentation to the class or panel.
- • T2: Answer questions citing your evidence.
- • T3: Record peer feedback on clarity and persuasiveness.
- • T4: Note one question you could not fully answer.
- • T5: Submit your delivered presentation and feedback notes.
- • E1: A biomedical design advances when test evidence is compared with explicit user needs, criteria, constraints, risks, and failure modes, then used to justify a documented revision.
- • E2: A design improves when evidence is compared with explicit criteria and constraints.
- • E3: You can present a complete design and cite the evidence behind each choice.
Measurements: No patient measurement is supplied unless it appears explicitly in E1-E3 or F1. Do not invent a value.
Figure finding: Teaching diagram for ER presentation. Trace the labeled system, test, or design relationship and identify which evidence should trigger revision. This is a teaching model, not patient or experimental data.
Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.
- • The solution must address the stated need in ER presentation.
- • The decision must be supported by E1-E3.
- • The final product must make the success criteria visible.
- • Complete the work inside the 80-minute block.
- • Use only supplied or teacher-approved materials and evidence.
- • Do not trade , accessibility, or privacy for speed.
- • and evidence quality: must pass before scoring other criteria.
- • User need and effectiveness: highest scored criterion.
- • Time, cost, and ease of use: compare only after and effectiveness pass.
Test evidence: For each option, record the E1-E3 result that supports or fails each criterion. Do not assign a score without a named observation.
- Version or option tested
- Criterion met or missed
- Evidence ID and result
- Revision made
- Reason for the revision
- Need and user
- Criteria and constraints
- Chosen option and evidence
- Test result
- Revision and reason
Students often think Students often think the presentation ends when the last slide does, so the Q&A is just a formality to survive.. The trap: That is a trap because the Q&A is where trust is won or lost; an answer pulled from your own evidence proves the design is real, while a guess signals you do not fully understand what you built.
ER presentation delivery record
Delivery: presented the problem-to-solution arc to the class in 6 minutes 40 seconds.
Questions I answered with my evidence:
- Asked how I know turnover, not room count, is the problem: I cited the flow data showing idle rooms during long waits.
- Asked whether visibility hurts privacy: I pointed to the privacy curtains in my floor plan.
Peer feedback on clarity and persuasiveness: peers said the results slide was the most convincing and that the problem slide could use one clearer number up front.
One question I could not fully answer: a peer asked what the turnover process costs in nurse workload. I did not have that data (it is my known evidence gap). How I would address it: run a short staffing-time study and add the result to the portfolio.
This model shows the level of evidence and organization needed to complete: The delivered ER design presentation with peer feedback recorded and a written note on one question that could not be fully answered, plus how to address it.
- State the question and method.
- Present the observations and data with units.
- Explain the result, limitations, and next investigation.
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 the presentation file and feedback notes on Schoology.

Practice: try a question, then check your answer▸
Claim ceiling for this check: Today's evidence supports a classroom claim about ER presentation. It cannot prove causation, diagnose a real patient, or justify action outside this room.
A panelist asks a question you did not prepare for. What is the strongest move: guess confidently, or something else?
Write an answer and pick a confidence to unlock the key.
Fast retrieval with instant answers, not the commit-then-reveal check above. Try each from memory first: write what you remember about the earlier units, then check yourself here.
Missed class or ready for more?▸
Run this before you touch the bench. It is built from the real lab procedure, so the decisions you make here are the ones you will make with the equipment in your hands.
I can name the procedure's purpose and the evidence I will record. I can state today's specific hazards and the control for each. If this deck does not name them, I ask Mr. Mendoza before I touch anything. My data table is ready before materials are handled.
Finish the checklist before you handle any material.
- • Wear the required PPE, keep the bench clear, handle equipment only as directed, and know where the eyewash, sink, and spill kit are before you start.
- • Human samples and data stay private: label with a code, never a name, and dispose of materials in the correct waste container, then wash your hands.
- 1Before materials are handled, identify the purpose, variables or comparison, controls, measurement units, and stop-work condition.
- 2Deliver your presentation to the class or panel.
- 3Answer questions citing your evidence.
- 4Record peer feedback on clarity and persuasiveness.
- 5Note one question you could not fully answer.
- 6Submit your delivered presentation and feedback notes.
- 7Record each result in the prepared table before interpreting it. Mark missing, repeated, or invalid results truthfully.
- 8Complete the named cleanup and waste route, remove PPE safely, wash hands when required, and confirm the station is ready for the next group.
| Trial or sample ID | Independent condition | Measured result with units | Observation before interpretation | Quality-control note |
|---|---|---|---|---|
Before the procedure, predict the result and cite the rule behind the prediction.
After the procedure, compare the result with the prediction and name one limitation or source of uncertainty.
