Supplied-data investigations and health-claim tasks
8 cases, 9 clearly labeled fictional/synthetic/de-identified datasets, 24 readiness-level tasks, 23 numeric calibrations, and 8 transfer cases. Grades 7-12; select depth tasks by prerequisites and readiness, not age alone.
Health and nutrition work uses fictional, synthetic, de-identified, or educator-supplied public records. It is not medical advice, does not diagnose, screen, treat, or prescribe, and never grades a learner body, disclosure, food choice, mood, sleep, fitness, weight, or medical status. Students’ own health, diet, sleep, fitness, or mood data are never collected or graded. Any tasting, cooking, allergen exposure, or food handling requires educator approval and an opt-out alternative.
Completion evidence is an evidence-based health-claim evaluation plus a practical nutrition or food-safety task from supplied records. An observed practical, if approved, is recorded separately from paper analysis.
Unit 1: Body-system cooperation in a fictional baseline record [systems-baseline]
Inputs, tasks, answers, and transfer. Science criteria: 1, 2, 3, 4, 5. Learning pathway.
Sources: NIH ODS: Calcium consumer fact sheet.
materials: Use the supplied systems-baseline-records records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain systems-baseline, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: How can a fictional baseline record show cooperation among body systems without grading a learner body?
prerequisites: Can name major body systems and read a small table.
variables: Pulse and breathing values are outcomes; activity context is a condition; learner identity is deliberately absent.
controls: Use the same fictional source and units for every student.
replication: Compare multiple de-identified records rather than repeating a personal measure.
analysis: Compute means and explain system cooperation with limits.
Uncertainty: Resting measures vary with timing, recent activity, equipment, stress, hydration, and measurement method. A single baseline supports a systems explanation, not a diagnosis.
Evidence: Completion evidence is a systems explanation tied to the fictional record, plus a note that the record is not personal diagnosis or comprehensive health credit.
Unit 2: Adolescent nutrient variation from supplied records [adolescent-micronutrients]
Inputs, tasks, answers, and transfer. Science criteria: 1, 2, 3, 4, 5. Learning pathway.
Sources: NIH ODS: Iron consumer fact sheet; NIH ODS: Calcium consumer fact sheet; NIH ODS: Vitamin D consumer fact sheet.
materials: Use the supplied adolescent-micronutrient-day records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain adolescent-micronutrients, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: How do adolescent nutrient recommendations and variation change the interpretation of a supplied food record?
prerequisites: Can distinguish macronutrients, micronutrients, and units.
variables: Nutrient intake and reference amount are compared; age/sex/diet pattern is context, not student disclosure.
controls: Use the same fictional day and public source rows.
replication: Use a second fictional day for transfer rather than asking students for personal intake.
analysis: Calculate percent of reference amount and state why one record is limited.
Uncertainty: One day of intake cannot represent a usual pattern. Food databases, fortification, absorption, and medical needs add uncertainty.
Evidence: Completion evidence is a nutrient-variation explanation and a supplied-data comparison, not a prescription to eat, restrict, or supplement.
Unit 3: Serving-size scaling and neutral energy arithmetic [label-energy]
Inputs, tasks, answers, and transfer. Science criteria: 3, 4, 5. Learning pathway.
Sources: FDA: How to understand and use the Nutrition Facts Label; FDA: Added sugars on the Nutrition Facts Label.
materials: Use the supplied label-serving-record records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain label-energy, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: How does serving-size arithmetic change a health claim about a packaged food?
prerequisites: Can multiply decimals and read a Nutrition Facts label.
variables: Servings used, calories, added sugar grams, and Daily Value are the table variables.
controls: Use the same fictional label and do not substitute personal food records.
replication: Repeat with a changed fictional label.
analysis: Scale each label fact before interpreting a claim.
Uncertainty: Labels round values; portion estimates vary; metabolism differs. These calculations describe the label record only.
Evidence: Completion evidence is correctly scaled label arithmetic and a boundary statement against personal intake targets or dieting prescriptions.
Unit 4: Food-safety and allergen-control scenario audit [food-safety-allergen]
Inputs, tasks, answers, and transfer. Science criteria: 2, 3, 5. Learning pathway.
Sources: CDC: Preventing food poisoning; FDA: Food allergies.
materials: Use the supplied food-safety-records, allergen-control-record records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain food-safety-allergen, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: How can a food-safety claim be evaluated without handling food or exposing anyone to allergens?
prerequisites: Can read a checklist and distinguish hazard, risk, and missing evidence.
variables: Temperature, label status, tool use, and container labeling are recorded variables.
controls: Use fictional records only; educator approval is required for any real food procedure.
replication: Audit a second scenario with changed records.
analysis: Identify risk-reduction steps and state what evidence is missing.
Uncertainty: Scenario records may omit time, thermometer accuracy, ingredient labels, or cleaning evidence. Missing safety evidence is not the same as safety.
Evidence: Completion evidence is a written safety/allergen audit plus a practical paper task using supplied records. Observed food handling, if any, is separately approved.
Unit 5: Fitness recovery as function evidence, not physique evidence [fitness-recovery]
Inputs, tasks, answers, and transfer. Science criteria: 1, 2, 3, 4, 5. Learning pathway.
Sources: CDC: Physical activity guidelines for children.
materials: Use the supplied fitness-recovery-record records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain fitness-recovery, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: What can a supplied recovery curve support, and what can it not judge?
prerequisites: Can subtract and read a time series.
variables: Minute and heart rate are recorded; activity context is described but not personally performed.
controls: Use a supplied model curve, not student exercise records.
replication: Analyze a changed curve with the same method.
analysis: Calculate change and identify confounders.
Uncertainty: Recent sleep, hydration, illness, medication, stress, warm-up, sensor placement, and activity type can change recovery data.
Evidence: Completion evidence is interpretation of a supplied recovery curve and limits, with no personal fitness disclosure required.
Unit 6: Sleep and stress pattern analysis with non-clinical boundaries [sleep-stress-boundaries]
Inputs, tasks, answers, and transfer. Science criteria: 1, 2, 3, 4, 5. Learning pathway.
Sources: CDC: About sleep.
materials: Use the supplied sleep-stress-fictional records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain sleep-stress-boundaries, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: How can sleep and stress data be interpreted without collecting private information or diagnosing?
prerequisites: Can average a small time series and explain association versus cause.
variables: Fictional sleep hours and stress rating are variables; personal identity is absent.
controls: Use supplied fictional records and approved help-seeking language.
replication: Compare another de-identified or fictional summary.
analysis: Calculate averages, describe association, and state non-clinical limits.
Uncertainty: A five-day pattern is short and report-like. Association between hours and rating does not prove cause or diagnose a sleep disorder or mental-health condition.
Evidence: Completion evidence is non-clinical interpretation of fictional data, clear opt-out boundaries, and appropriate help-seeking language.
Unit 7: Immunity and prevention with denominators [immunity-prevention]
Inputs, tasks, answers, and transfer. Science criteria: 1, 2, 3, 4, 5. Learning pathway.
Sources: CDC: Types of immunity; CDC: About flu.
materials: Use the supplied immunity-classroom-model records, assigned source sections, calculator and an accessible graph or diagram. No physical apparatus is required.
record: Retain immunity-prevention, the selected level, original inputs and first attempt, source/date, system and axes, units, assumptions, calculation/graph, uncertainty, correction and fresh transfer. Link only to the stated science criteria.
review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: How do immunity concepts and denominators change a prevention claim?
prerequisites: Can compute percentages and define immunity terms.
variables: Exposed count, model cases, and prevention note are variables.
controls: Use synthetic model groups with equal denominators.
replication: Use a changed denominator and case count.
analysis: Calculate attack rates and compare absolute differences.
Uncertainty: Small groups, exposure differences, testing definitions, and unmeasured behavior can change apparent attack rates.
Evidence: Completion evidence is a denominator-based prevention explanation and a limit statement, not a medical recommendation.
Unit 8: Health-claim evidence quality and risk interpretation [claim-quality]
Inputs, tasks, answers, and transfer. Science criteria: 1, 2, 3, 4, 5. Learning pathway.
Sources: MedlinePlus: Evaluating health information; NIH NCCIH: Know the Science.

review: An educator reviews prerequisites, source interpretation, reasoning and accessibility before assessment. A paper response does not certify unobserved practical technique; approved hands-on work requires a separate record.
question: What evidence quality checks should come before accepting a health claim?
prerequisites: Can compute percentage risk and distinguish correlation from causation.
variables: Total participants, outcome cases, comparison group, source purpose, and design note.
controls: Use the same synthetic risk table and source-evaluation checklist.
replication: Evaluate a changed synthetic risk table and a new source note.
analysis: Compute absolute risk, relative change, and evidence-quality limits.
Uncertainty: A small or biased study, weak outcome definition, confounding, missing funding information, or short follow-up can lower evidence quality.
Evidence: Completion evidence is an evidence-based health-claim evaluation plus a practical nutrition/food-safety task from supplied records.
