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 the biology becomes something a student can think with rather than just recall. Memory is associative: a fact lashed to a story, 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 (where in the world this matters — epidemiology, ecology, agriculture) and soft social studies (the ethical and policy stakes). 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 & quantitative · Ethics · Economics · Technology & engineering · Art & 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. Every unit names the specific math the biology actually requires, done inside the lab context where it means something. 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 biology 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 biological big idea and the real-world anchor that carries the History, Reading, and Writing core — a doorway, not a detour.
| Unit | Biology big idea | Integration anchor |
|---|---|---|
| 01 Chemistry of Life | Water’s strange properties make life possible. | Water & the origins-of-life debate — how the molecule’s chemistry frames where life began. |
| 02 Cell Structure | Cells are the basic unit of life, revealed by tools. | The invention of the microscope — Hooke & Leeuwenhoek seeing cells for the first time. |
| 03 Cellular Energetics | Energy flows through living systems via photosynthesis & respiration. | Photosynthesis & the climate / carbon cycle — cellular chemistry scaled up to the planet. |
| 04 Cell Communication & Cycle | Cells signal and divide — division gone wrong is cancer. | Cancer, Henrietta Lacks & the HeLa ethics — consent, race, and the cells that never stopped dividing. |
| 05 Heredity | Traits pass from parent to offspring by predictable rules. | Mendel’s peas & the history of genetics — a monk’s garden becomes the foundation of inheritance. |
| 06 Gene Expression | Genes are read and regulated to build an organism. | The Human Genome Project & CRISPR ethics — reading the code, and the power to rewrite it. |
| 07 Natural Selection | Populations change over time through differential survival. | Darwin, the Beagle & the Galápagos — the voyage and the finches that reshaped biology. |
| 08 Ecology | Organisms and environments shape one another. | John Snow’s Ghost Map — epidemiology & public health born from a single map. |
Big idea: organisms and environment are inseparable. Anchor: in 1854 London blamed “bad air”; John Snow proved cholera was waterborne. Question: students plot the same deaths on a map, find the Broad Street pump, and reason to Snow’s conclusion — doing epidemiology. Connection back: this is ecology — a population studied in its environment with spatial data. A student who solves a murder mystery with a map will never confuse ecology for a vocabulary list again.
Math never drives a unit, but biology uses it constantly — always anchored to the organism or measurement at the bench. Here is the quantitative skill each unit actually uses, done inside the lab context rather than as a parallel curriculum.
| Unit | Applied math (in the lab context) |
|---|---|
| 01 Chemistry of Life | pH and logarithms; molarity & concentration; the basics of water potential. |
| 02 Cell Structure | Surface-area-to-volume ratios; scale, magnification, and unit conversion. |
| 03 Cellular Energetics | Reaction rates; graphing O₂ / CO₂ production over time; reading slopes. |
| 04 Cell Communication & Cycle | Ratios and proportions in cell-cycle timing; dose–response graphing. |
| 05 Heredity | Probability, Punnett ratios, and chi-square goodness-of-fit testing. |
| 06 Gene Expression | Codon combinatorics & sequence counting; measuring gel-band migration. |
| 07 Natural Selection | Hardy–Weinberg (p² + 2pq + q²); allele-frequency algebra. |
| 08 Ecology | Exponential & logistic growth curves; mark–recapture estimates; biodiversity indices. |
Students do the chi-square inside the genetics cross, the growth curve inside the population study, the surface-area ratio inside the cell lab. The number always means something because it is attached to a result they produced — never a worksheet detached from the biology.
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.
| Unit | Not Yet | Approaching | Mastered | Tokens |
|---|---|---|---|---|
| 01 Chemistry of Life | ◯ | ◯ | ◯ | ______ |
| 02 Cell Structure | ◯ | ◯ | ◯ | ______ |
| 03 Cellular Energetics | ◯ | ◯ | ◯ | ______ |
| 04 Cell Comm. & Cycle | ◯ | ◯ | ◯ | ______ |
| 05 Heredity | ◯ | ◯ | ◯ | ______ |
| 06 Gene Expression | ◯ | ◯ | ◯ | ______ |
| 07 Natural Selection | ◯ | ◯ | ◯ | ______ |
| 08 Ecology | ◯ | ◯ | ◯ | ______ |
A student who walks through all eight anchors finishes understanding that biology is woven into history, governed by data, and weighted with ethical consequence — the truest thing we can teach them about the subject.
