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 science 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 (where in the world this matters — industry, resources, environment) 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. Marine biology runs on measurement and data; every unit names the specific math the science actually requires, done inside the lab 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 marine 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 marine-biology big idea and the real-world anchor that carries the History, Reading, and Writing core — a doorway, not a detour.
| Unit | Marine Biology big idea | Integration anchor |
|---|---|---|
| 01 The Ocean Environment | The ocean is a layered physical system — zones, salinity, temperature, pressure, light, currents. | HMS Challenger and the birth of oceanography — trace the voyage; graph temperature–salinity–depth profiles. |
| 02 Plankton & Primary Production | Microscopic drifters at the surface are the base of the ocean food web. | The microscope and the discovery of the microscopic ocean — tow, count, and identify plankton. |
| 03 Marine Plants, Algae & Kelp Forests | Seaweeds, kelp forests, and seagrasses build habitat and fix carbon. | Seaweed in food, industry, and history — press and key out algae; measure cover and biomass. |
| 04 Marine Invertebrates | The invertebrate phyla show how body plans solve the problems of ocean life. | Comparative anatomy and the long project of classification — dissect and key an invertebrate. |
| 05 Fish & Sharks | Fish anatomy, buoyancy, and gills adapt vertebrates to life underwater. | Fisheries and the age of ocean exploration — study morphology; reason about buoyancy and drag. |
| 06 Marine Reptiles, Birds & Mammals | Air-breathing tetrapods returned to the sea to dive and stay warm. | The history of whaling and conservation — model blubber insulation; read dive-depth data. |
| 07 Ocean Ecosystems | Reefs, estuaries, and the deep sea are structured by food webs and symbiosis. | Darwin and the coral-reef puzzle — survey a community with a quadrat; quantify diversity. |
| 08 Humans & the Ocean | Fishing, pollution, and climate change reshape the ocean; conservation can protect it. | Silent Spring and the conservation movement — analyze real catch and population data. |
Big idea: the ocean is a structured, measurable, living system, and the way to know it is to go out and read what the instruments bring back. Anchor: a British warship refitted as a floating laboratory sailed roughly 70,000 nautical miles (1872–76), dredged the deep sea, mapped the floor, and catalogued more than 4,000 species new to science — overturning the “azoic hypothesis” that nothing lived in the deep. Question: students read a temperature–depth profile, scale a dredge haul, and key out a specimen. Connection back: each unit is one instrument lowered over Challenger’s side — this is how marine biology turns a hidden world into a known one.
Math never drives a unit, but marine biology uses it constantly — always anchored to the observation 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 The Ocean Environment | Graphing temperature–salinity–depth profiles; seawater density; depth and pressure conversions. |
| 02 Plankton & Primary Production | Plankton counts scaled to cells per litre; sampling ratios; production rates. |
| 03 Marine Plants, Algae & Kelp Forests | Percent cover and biomass from quadrats; growth rates; area estimation. |
| 04 Marine Invertebrates | Counts and ratios across phyla; symmetry and body measurement; proportional scaling. |
| 05 Fish & Sharks | Morphometric ratios; buoyancy and density; length–weight relationships. |
| 06 Marine Reptiles, Birds & Mammals | Dive-depth and duration time-series; surface-area-to-volume ratios; averages and ranges. |
| 07 Ocean Ecosystems | Diversity and abundance indices; quadrat and transect counts; energy-transfer percentages. |
| 08 Humans & the Ocean | Catch and population trends; percent change over time; reading line graphs of stocks and CO₂. |
Students do the plankton count inside the tow-net lab, the percent-cover calculation inside the quadrat survey, the morphometric ratio inside the fish study. The number always means something because it is attached to a result they produced — never a worksheet detached from the marine 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 The Ocean Environment | ◯ | ◯ | ◯ | ______ |
| 02 Plankton & Primary Production | ◯ | ◯ | ◯ | ______ |

| 04 Marine Invertebrates | ◯ | ◯ | ◯ | ______ |
| 05 Fish & Sharks | ◯ | ◯ | ◯ | ______ |
| 06 Reptiles, Birds & Mammals | ◯ | ◯ | ◯ | ______ |

A student who walks through all eight anchors finishes understanding that marine biology is how humans learned to read a hidden world, and that every name on the page was once a discovery someone sailed for — the version of the subject a student keeps.
