How this lesson connects
Keep using what you learned last class: A health message's tone changes behavior because fear only moves people when paired with a clear action, so tone and next-step together decide whether anyone acts and whether they keep trusting you. Today: A message drives action because it is written at the audience's reading level and ends in a specific step, so the person both understands it and knows exactly what to do.
Optional: listen or watch a unit review▸

💡 Big idea: A message drives action because it is written at the audience's reading level and ends in a specific step, so the person both understands it and knows exactly what to do.
- 0-5 minWarm-up: who is your target audience and what do they worry about most?
- 5-20 minDefine audience and main concern; write your one-sentence core message
- 20-40 minDraft a specific call to action and check it is actionable and realistic
- 40-55 minAssess reading level; simplify any jargon that the audience would not know
- 55-70 minAdd citation for the evidence behind your recommendation
- 70-80 min: can your partner identify your audience, message, and action step?
- • Today you write the actual message your product will deliver.
- • We start by defining exactly who will read it and what they already know.
- • A core message in one sentence forces clarity: if you can't say it simply, you don't know it well enough.
- • The call to action is the most important line: it tells people what to do with the information.
- • A call to action must be specific enough that the audience knows exactly what to do.
- • Reading level should match the audience: plain language increases comprehension and action.
- • Citations behind health recommendations show the message is not opinion.
PLTW connection and today's work
Open Problem 5 in your myPLTW course shell and navigate to the current communication activity, then draft an evidence-based public health message tailored to a specific audience.
Today's stopping point: The risk communication debate is done; message drafting is an early communication milestone, so check your activity guide.
PLTW activity titles identify the course connection. If your account will not open, use the posted materials for today and tell Mr. Mendoza. Do not mark an online activity complete unless you completed it.

A message drives action because it is written at the audience's reading level and ends in a specific step, so the person both understands it and knows exactly what to do.
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: How do you write one sentence about flu shots that a busy John Hay parent will read, believe, and act on before scrolling past?

Visual or model: F1. F1. A lesson illustration or teaching diagram for Message draft. 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 message draft.
- 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: How do you write one sentence about flu shots that a busy John Hay parent will read, believe, and act on before scrolling past?
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.
- • audience: The specific group of people a product, message, or design is created for, whose needs and abilities shape every design choice.
- • privacy: A person's right to control who can access their personal or health information and how that information is shared.
- • usability: Use the lesson context and glossary entry to explain usability in your own words.
- • recommendation: A clear, evidence-based suggestion for what action to take, drawn from analyzing data, results, or a patient's situation.
- • evidence: The facts, data, and cases that carry your claim. Opinions are free; evidence costs homework.
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 clear public-health communication identifies a specific audience, presents one evidence-based main message and action, uses familiar language, and states what is known and uncertain without overstating risk.
Limit: A classroom communication product is not an official public-health advisory and still requires audience testing, current local guidance, and review by the responsible authority before release.
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.
Your message names an audience and an evidence-based action.
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-2027-04-26 · Simulated classroom evidence scenario
Your role: biomedical design team member
Decision: Your team must decide what the evidence from message draft supports before submitting the claim-evidence-reasoning response named on today's page.
- • No citation backs the flu shot claim in your draft yet, so find that source before sending it.
- • Write the flu shot sentence in plain words a busy parent can read fast, ending with one action.
- • Use formal scientific vocabulary in the flu shot sentence, because precise technical wording makes the message sound more credible.
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: Today's evidence supports a classroom claim about message draft. It cannot prove causation, diagnose a real patient, or justify action outside this room.
Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.
For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.
Mean, median, and range keep the measurement unit. Order the values before finding the median.
Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.
- • The solution must address the stated need in message draft.
- • 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 think a health message sounds more credible and convincing when it uses formal, scientific vocabulary.. The trap: Big words shrink your audience: if people cannot read the message easily, they cannot act on it, no matter how correct it is. Plain language is not dumbing down; it is the difference between a message that gets acted on and one that gets scrolled past.
Audience and concern: Renters and homeowners in older houses near the lake, who have heard of carbon monoxide but do not know whether their home actually needs a detector.\nCore message (one sentence): A working carbon monoxide alarm on each floor warns you before an invisible gas leak from a furnace or water heater can make your family sick, and it costs about the price of a fast-food meal.\nCall to action: This weekend, put one carbon monoxide alarm on each level of your home, especially near sleeping areas, and press the test button to make sure it beeps.\nReading-level note: I aimed for about a 6th-grade reading level. I used short sentences and everyday words ('alarm' and 'beeps' instead of 'detection device'), and I named exactly where to place it so no one has to guess.\nEvidence citation: CDC, 'Carbon Monoxide Poisoning: Prevention Guidelines,' cdc.gov/carbon-monoxide (reports that CO alarms give early warning and that CO poisoning sends thousands to the emergency room each year).
This model shows the level of evidence and organization needed to complete: Worked CER on a parallel case: models the message-draft step (named audience, one evidence-backed core message, a specific call to action, a reading-level note, and a citation) on a different public health topic so you can copy the format, not the answer.

Practice: try a question, then check your answer▸
Claim ceiling for this check: Today's evidence supports a classroom claim about message draft. It cannot prove causation, diagnose a real patient, or justify action outside this room.
Rewrite this so a busy parent reads and acts on it: 'Individuals are encouraged to obtain seasonal immunization to mitigate influenza transmission risk.' Keep it accurate and add a specific action.
Write an answer and pick a confidence to unlock the key.
