Integration is not decoration — it is a deliberate method for making each unit reach outward into history, reading, and writing first, then into geography, ethics, data, and economics, so health & nutrition becomes something a student can think with rather than just recall. Memory is associative: a fact lashed to a discovery, a controversy, and a consequence is held by a dozen threads instead of one.
Every unit radiates the same structured set of connections off the science spine — three tiers plus a quantitative lane. This is what keeps the cross-domain work rigorous instead of random.
| Tier | What it carries |
|---|---|
| Core spokes always required | History, Reading, Writing. Every unit names who discovered the idea and what they got wrong first, gives a real text to read (primary source, biography, living book — not a textbook chapter), and asks for writing in the student’s own voice. These run in every unit, no exceptions. |
| Standard spokes where they fit | Geography & public health (where in the world a health issue matters — food access, disease patterns, environment) and ethics & policy (the human stakes — medical ethics, public-health policy). Where a unit genuinely doesn’t carry these, we move them to the elective pool rather than fake a connection. |
| Elective spokes pick ~two of five | Data & statistics · Ethics of medicine · Economics of health · Technology & measurement · Media & design. Additive depth, never a substitute for the core. Letting students choose feeds wonder and lets faster students go deeper. |
| Applied-math lane always present | Math is not a spoke — we use math, we are not a math program. Reasoning about health leans on numbers constantly; every unit names the specific math the science actually requires, done inside the investigation context. The per-unit lane is on Page 3. |
Integration is graded as its own strand, separate from the science-mastery criteria. A student can be Mastered on the science and only Approaching on integration, or the reverse — which keeps the science bar pure while still rewarding cross-domain depth.
Every unit has an anchor built the same way. Each row names the unit’s health-science big idea and the real-world anchor that carries the History, Reading, and Writing core — a doorway, not a detour.
| Unit | Health & Nutrition big idea | Integration anchor |
|---|---|---|
| 01 Body Systems & Wellness | The body’s major systems work together, and “wellness” is a whole-person baseline you can measure as data. | William Harvey mapping the circulation of blood in 1628, overturning 1,400 years of Galen — pair with a popular-science reading and write how one careful observation toppled ancient authority. |
| 02 Nutrients & the Science of Food | Food supplies macronutrients and micronutrients — energy and building blocks — and type and amount matter, not the category. | The discovery of vitamins — Eijkman’s beriberi hens and Funk naming the “vital amine” — argue from the evidence why treating carbs or fats as a “bad category” is a mistake. |
| 03 Digestion, Metabolism & Energy | The body breaks food down and extracts energy; a calorie is simply a unit of the energy the body needs. | Wilbur Atwater building the first calorimeter to measure food energy — students run the neutral energy-balance arithmetic, energy in versus energy out, as science, never as a diet prescription. |
| 04 Building a Healthy Diet | A balanced diet is built from evidence — labels, serving sizes, and guidelines — not fads or “detox” claims. | The story of the nutrition-label mandate and dietary guidelines; students analyze real labels and debunk a “detox” claim using how the liver and kidneys actually clear the body. |
| 05 Physical Fitness & Exercise Science | Fitness has measurable components, and the body adapts to activity — measured by function, never by physique. | The origins of exercise physiology; students collect heart-rate-recovery data and reason about how the body adapts to activity, keeping the focus on function and evidence rather than looks. |
| 06 Mental Health & Stress | The stress response, sleep, and mental well-being can be understood and self-tracked as data — with support from trusted adults and professionals. | Hans Selye naming the stress response in the 1930s; students self-track sleep and stress as data and read about the science supportively — never as self-diagnosis, always pointing toward trusted adults and professionals. |
| 07 Disease, Immunity & Prevention | The immune system defends the body, diseases spread in patterns, and prevention works when it is evidence-based. | James Lind and the scurvy trial — the first recorded controlled clinical trial, the comparison groups that made it fair, the forty-year delay, and the birth of evidence-based prevention. |
| 08 Health Decisions & Media | Health claims in media must be judged on evidence — and correlation is not causation. | A modern nutrition-headline case study — students separate correlation from causation, weigh supplements against whole food, and write a critical review of a real health claim. |
Big idea: to prove a cause, you compare — a real cause is shown by a controlled test, not a convincing story. Anchor: aboard HMS Salisbury in 1747, ship’s surgeon James Lind split twelve scurvy-sick sailors into six matched pairs, each given a different suspected cure; the pair given citrus recovered within days, yet the Royal Navy ignored the result for more than forty years while thousands died. Question: students reconstruct the trial — naming the comparison groups, the single variable, and why a control makes the test fair. Connection back: this is evidence-based prevention and the logic of the controlled trial — the same reasoning that lets a reader spot a missing comparison group in a modern health headline.
Math never drives a unit, but health & nutrition uses it constantly — always anchored to a measurement or a claim at the bench. Here is the quantitative skill each unit actually uses, done inside the investigation context rather than as a parallel curriculum.
| Unit | Applied math (in the lab context) |
|---|---|
| 01 Body Systems & Wellness | Reading baseline measurements (resting heart rate, breaths per minute); averages; simple unit conversions. |
| 02 Nutrients & the Science of Food | Converting grams of macronutrient to energy (4, 4, and 9 kcal per gram); reading percent Daily Value. |
| 03 Digestion, Metabolism & Energy | Energy-balance arithmetic (energy in versus energy out); the calorie as a unit of energy; neutral totals, not targets. |
| 04 Building a Healthy Diet | Serving-size ratios; scaling a label to the portion eaten; proportional reasoning across a day of food. |
| 05 Physical Fitness & Exercise Science | Heart-rate-recovery rates over time; plotting a recovery curve; reading change as data, not as a verdict. |
| 06 Mental Health & Stress | Self-tracked sleep and stress data over time; averages and trends; reading your own numbers without judgment. |
| 07 Disease, Immunity & Prevention | Comparison groups and controls; transmission math (spread rates, doubling); percentages and rates. |
| 08 Health Decisions & Media | Correlation versus causation; relative versus absolute risk; sample size and why a comparison group matters. |
Students do the energy-balance arithmetic inside the digestion-and-metabolism investigation, the serving-size math inside the label analysis, the heart-rate-recovery calculation inside the fitness measurement. The number always means something because it is attached to a result they produced — never a worksheet detached from the science.
Integration is its own strand. Track each unit’s integration level across the year — Not Yet, Approaching, or Mastered — separate from the science-mastery rubric. Record demonstration tokens earned in the final column.

A student who walks through all eight anchors finishes understanding that health & nutrition is how humans learned to tell what actually works from what only sounds convincing, and that every fact on the page was once a claim someone had to test — the version of the subject a student keeps.
