💡 Big idea: Evidence can only drive a decision when it is integrated, cited, and readable by the people at risk, so a complete exposure map joins pathway, dose, and mitigation into one document a non-scientist can act on and confirms it in the tracker to close the Problem 4 loop.
- 0-5 minWarm-up: what is the one thing your map is missing right now?
- 5-25 minCombine pathway diagram, data analysis table, and mitigation notes into one document
- 25-45 minLabel source, pathway, dose, at-risk population; add citations for all data
- 45-60 minReadability check: swap with a partner and note one confusing label to fix
- 60-72 minFix flagged items; confirm tracker shows Problem 4 complete
- 72-80 minSubmit the exposure map, and screenshot your myPLTW confirmation
- • Today is assembly day: your pathway diagram, , and mitigation notes come together.
- • The finished exposure map is a document a community group could actually use.
- • We'll check that every number has a citation and that a neighbor could read it.
- • By the end of class, Problem 4 is submitted and checked off in your tracker.
- • All quantitative claims in the map need a source citation.
- • The map should be readable by a non-scientist, not just a trained toxicologist.
- • Confirming submission in the tracker closes the Problem 4 evidence loop.

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.
Mitigation works by targeting either the source or the exposed population, so the best recommendation is the one whose risk reduction and cost make it feasible enough to actually get adopted.
Evidence can only drive a decision when it is integrated, cited, and readable by the people at risk, so a complete exposure map joins pathway, dose, and mitigation into one document a non-scientist can act on and confirms it in the tracker to close the Problem 4 loop.
A detective board holds observations, possible explanations, and one next question.
- Which notes are direct observations?
- Which notes are explanations?
- What new evidence would separate the explanations?
Keep observations separate from explanations, then collect the evidence that can distinguish the options.
Biomedical investigations use controlled procedures and validated measurements, not intuition alone.
- • Board notes map to E1-E3.
- • Possible explanations map to the decision options.
- • The next question maps to the evidence-based action.
Driving question: Your Problem 4 exposure map has to convince a real community, not just a toxicologist, so how do you combine your pathway, dose data, and mitigation into one cited document that a parent or a city council member could actually read and use?
What you already know: Mitigation works by targeting either the source or the exposed population, so the best recommendation is the one whose risk reduction and cost make it feasible enough to actually get adopted.

Visual or model: F1. F1. A lesson illustration or teaching diagram for Exposure map submit. 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 Exposure map submit.
- Organize the observation with a stable evidence ID.
- Apply this rule: Keep observations separate from explanations, then collect the evidence that can distinguish the options.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: Your Problem 4 exposure map has to convince a real community, not just a toxicologist, so how do you combine your pathway, dose data, and mitigation into one cited document that a parent or a city council member could actually read and use?
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.
All quantitative claims in the map need a source citation.
Limit: E1 supplies context or an observation; it does not by itself establish the explanation.
Evidence can only drive a decision when it is integrated, cited, and readable by the people at risk, so a complete exposure map joins pathway, dose, and mitigation into one document a non-scientist can act on and confirms it in the tracker to close the Problem 4 loop.

Your exposure map integrates pathway, data, and mitigation.
Limit: E3 supports only the result or product criterion named here; it cannot justify a broader clinical or causal claim.
PLTW-BFH-2027-04-12 · Simulated classroom evidence scenario
Your role: biomedical design team member
Decision: Your team must decide what the evidence from Exposure map submit supports before submitting the lab report 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 lab report.
Claim ceiling: The supplied lesson evidence can support an observation, pattern, classroom mechanism, or next-step decision about Exposure map submit. It cannot by itself prove causation, establish a real clinical diagnosis, or justify action outside this classroom task.
= 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 think a map is finished once the science is correct, treating clear writing and citations as optional polish rather than part of the evidence.. The trap: Uncited or unreadable evidence cannot be acted on, so a technically correct map that a non-expert cannot follow or verify fails at its actual job of informing a community. Communication and sourcing are not decoration; they are what make the evidence usable.
Title: Lead Exposure Map, Older-Housing Neighborhood.
1. Pathway: lead pipes (source) to drinking water (medium) to ingestion (route) to nervous system (target). Most at-risk population: young children.
2. Data: average tap lead 13.2 ppb; highest home 22 ppb; EPA action level 15 ppb (cited: EPA Lead and Copper Rule). Two of five homes met or exceeded the action level.
3. Mitigation: filters now (fast, low cost) plus pipe replacement (permanent). Recommended both, filters first.
4. Plain-language risk statement for non-experts: 'Some homes here have more lead in their tap water than the safety limit allows. Lead is most harmful to young children. Using a certified filter and replacing old pipes lowers the risk.'
Citations: EPA Lead and Copper Rule action level (epa.gov); city water-quality report.
Tracker: marked Problem 4 exposure map as submitted.
| Map element | Content |
|---|---|
| Source | Lead service pipes |
