How this lesson connects
Keep using what you learned last class: You define a metric with units, a control, and a pass/fail line so that a result can be traced to the prototype rather than to chance or wishful thinking. Today: Pollution sources were sited by past decisions, so environmental health burdens fall harder on lower-income and marginalized neighborhoods, and exposure data reveals that uneven pattern.
Optional: listen or watch a unit review▸

- 0-5 minWarm-up: name one way where you live might affect your health
- 5-20 minRead briefing; choose stakeholder role and list two reasons your position is fair
- 20-40 minSmall-group debate tracking which claims cite exposure data
- 40-55 minFull-class debrief: which stakeholder argument was hardest to refute?
- 55-70 minReflection: how should data change who pays for exposure reduction?
- 70-80 minExit ticket: one sentence on what counts as fair based on the data
- • Environmental justice asks: does everyone face the same health risk from pollution?
- • Today we look at exposure data for two neighborhoods side by side and ask who is responsible.
- • You'll argue from a specific stakeholder's point of view: resident, company, or regulator.
- • Good arguments use the actual numbers, not just feelings about fairness.
- • Exposure data can show whether pollution risk varies by neighborhood income or race.
- • Stakeholder roles shape how people interpret the same exposure numbers.
- • decisions require evidence, not just opinion.

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.
You define a metric with units, a control, and a pass/fail line so that a result can be traced to the prototype rather than to chance or wishful thinking.
Pollution sources were sited by past decisions, so environmental health burdens fall harder on lower-income and marginalized neighborhoods, and exposure data reveals that uneven pattern.
A review board sorts scientific evidence, stakeholder needs, possible benefits, possible burdens, and uncertainty before choosing a policy.
- Which statements are scientific evidence?
- Which statements express a value or priority?
- Who receives the benefit and who carries the burden?
Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
A review-board model organizes reasoning but does not make one ethical principle automatically outweigh every other principle.
- • Evidence cards map to source-backed findings.
- • Stakeholder cards map to affected people and priorities.
- • The recommendation maps to an explicit tradeoff with a named uncertainty.
Driving question: Two Cleveland neighborhoods sit half a mile apart, but one shows higher measured pollutant exposure than the other, so who owes the residents an answer, and what does the data actually prove?
What you already know: You define a metric with units, a control, and a pass/fail line so that a result can be traced to the prototype rather than to chance or wishful thinking.
New idea: Pollution sources were sited by past decisions, so environmental health burdens fall harder on lower-income and marginalized neighborhoods, and exposure data reveals that uneven pattern.
Visual or model: F1. F1. A lesson illustration or teaching diagram for Environmental justice debate. 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 environmental justice debate.
- Organize the observation with a stable evidence ID.
- Apply this rule: Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: Environmental-health teams graph exposure measurements by place or time to identify a pattern that should be investigated, while keeping correlation separate from causation. Source: NIST Statistics Resources.
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.
- • : A poisonous substance produced by a living organism, such as bacteria, plants, or animals, that can damage cells or disrupt body functions.
- • exposure: Contact with a substance, agent, or condition that could affect health, such as a chemical, , or environmental factor.
- • dose: The measured amount of a drug or substance given at one time, chosen to be effective while staying safe for the patient.
- • pollutant: A harmful substance released into air, water, or soil that can damage ecosystems and human health.
- • : The gradual buildup of a substance, such as a , inside an organism faster than the body can break it down or remove it.
- • risk: The chance that a harmful event, such as getting a disease, will happen within a given group or time period.
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 defensible biomedical decision separates scientific evidence from value judgments, identifies who may benefit or be burdened, and states the uncertainty and tradeoffs that remain.
Limit: Scientific evidence can inform the options and likely consequences, but it cannot choose a single value-neutral answer.
Use science to estimate consequences, then state the value judgment and tradeoff that determine the decision.
Limit: A review-board model organizes reasoning but does not make one ethical principle automatically outweigh every other principle.
You can defend a stakeholder position using exposure evidence.
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-2027-04-07 · Simulated classroom evidence scenario
Your role: biomedical design team member
Decision: Your team must decide what the evidence from environmental justice debate supports before submitting the exit response named on today's page.
- • Hold residents responsible, because a neighborhood where litter and upkeep are ignored will end up with worse measured exposure.
- • Ask for the zoning records behind each pollution source before assigning responsibility, because exposure numbers cannot show who approved them.
- • Argue that past siting decisions about highways and factories placed the burden there, and cite the measured exposure gap.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the exit response.
Claim ceiling: Today's evidence supports a classroom claim about environmental justice debate. It cannot prove causation, diagnose a real patient, or justify action outside this room.
= final volume / sample volume. New concentration = starting concentration / dilution factor.
Mix 1 mL of sample to a final volume of 10 mL. The is 10. A 100 mg/mL starting sample becomes 10 mg/mL.
Use the same volume units before dividing. Concentration keeps its original concentration unit.
Apply the same setup to one supplied dilution or dose. Show the factor, new value, units, and a reasonableness check.
Students often think Students often assume that if pollution is worse in a poorer neighborhood, it is because the people there did something (littered, did not maintain their homes) to cause it.. The trap: That flips cause and effect. Exposure gaps usually trace to decisions made long before residents arrived, like where highways, factories, and waste sites were zoned, so blaming residents hides the actual source and lets the real decision-makers off the hook.
Parallel case (not today's prompt): An older apartment building draws its tap water through lead service lines installed decades ago, while a newer building across the street was plumbed with copper. Water testing shows the older building has a much higher lead level at the tap. Who bears responsibility for the residents' exposure, and what does the data actually prove?\n\nClaim: Because the older building's tap water carries lead well above the level considered safe while the newer building's water does not, the utility that owns the service lines and the property owner who left them in place share responsibility for reducing the exposure, since the data shows the risk comes from the pipes, not from anything the residents did.\n\nEvidence: The water samples show the older building averaged roughly 20 parts per billion of lead at the tap, above the 15 parts per billion action level, while the newer building measured near zero. Both buildings receive water from the same treatment plant and the same source, so the treated water entering each building started out the same. The only measured difference between the two water paths is the metal in the pipes, lead in the older lines and copper in the newer ones.\n\nReasoning: Lead does not appear in water on its own, it dissolves into the water as it sits in contact with lead pipes, so a higher reading at the tap points to the plumbing the water traveled through rather than to the residents' habits or choices. Because both buildings share the same source and treatment, that shared starting point rules out the treatment plant as the cause and isolates the service lines as the variable that changed the outcome. The residents cannot see, choose, or replace the buried lines they rent water through, so the burden of an exposure they did not create falls on the parties who control those lines, the utility that owns them and the owner responsible for the building's plumbing. The data proves where the lead is coming from, and that source is on the responsible parties' side of the tap.
This model shows the level of evidence and organization needed to complete: Parallel-case model for the Problem 4 environmental-justice discussion: it demonstrates the Claim, Evidence, Reasoning format and depth on a different exposure scenario (lead in tap water) so students can transfer the structure to their own one-sentence position without seeing today's answer.
