DIGITAL NATURALISM

For Educators

Three historical expeditions, Darwin’s Beagle, Wallace’s Malay Archipelago, and Wilson’s century of fieldwork, retold as voyages a student sails port by port. The point throughout is not that these men were right, but how they came to know: the app makes students commit to their own inference before revealing the historical one, and its field journal rewards reasoning over clicking.

How the pieces teach

• The guided voyage: “Set sail from the first port,” then “Continue the voyage” carries a student through the route in order, the map sailing with them. Every stop's panel ends with the way onward.

• Predict-and-check challenges: at key stops, students commit to an inference before reading the naturalist's conclusion: matching Punta Alta's fossil giants to living relatives, explaining seashells at 12,000 feet, sorting birds across the Wallace Line. Wrong answers get a reason they fail on the evidence, not just a red mark.

• The insights: evidence accumulates from ports visited and challenges solved (solving counts double), and each of the naturalist's great insights appears as a full card at the moment its evidence is complete. All of them collect under Insights on the expedition console for rereading.

• How the voyages connect: a timeline of the moments the story passes from hand to hand (Darwin's Journal recruiting Wallace, the Ternate letter, Wilson turning islands into equations), each linked to its place on the map.

• Share pages: every port has a plain, linkable page (/voyage/…) that works in a reading list or LMS assignment and hands the student into the interactive map at that exact stop.

Lesson flow 1 · Darwin: no eureka in the Galápagos (≈45 min)

The myth says Darwin saw the finches and understood. The record says he barely labelled them. This flow follows the evidence he actually weighed, in the order he met it.

• Punta Alta: students match five extinct giants to living relatives from anatomy hints, the inference Darwin made in the cliffs.

• The Andes crossing: seashells at 12,000 feet: flood, chance shapes, or risen sea floor? Commit before reading.

• Concepción: the earthquake lifts the coast several feet in a minute: the mechanism, felt.

• Galápagos: San Cristóbal: read what Darwin actually did there, and didn't. The revolution came later, in London.

Discussion

• Which single piece of evidence from this voyage do you find most convincing, and what alternative explanation would you have reached for in 1835?
• Why did Darwin need the fossils and the earthquake before the islands could mean anything?
• What does the gap between the myth and the record tell us about how science is usually told?

Lesson flow 2 · Wallace: drawing the line (≈45 min)

• The Rio Negro: same forest, different monkeys; students explain it before Wallace does.

• Sarawak: the Law: every species arises beside a closely allied one. The paper itself is one click away.

• Bali & Lombok: sort five birds into Asian and Australian sides across a strait you can see across, then meet the Line.

• Ternate: fever, Malthus, and the essay that forced the Origin into print.

• The thread: follow the letter to Down House and the joint reading neither author attended.

Discussion

• Wallace reached natural selection with no wealth, no university, and no Beagle. What did he have instead?
• The Wallace Line separates faunas, not climates. What kind of cause can draw a boundary that sharp?

Lesson flow 3 · Wilson: from ants to Half-Earth (≈45 min)

• Mobile, Alabama: a half-blind boy bends close to the small things, and finds a life's work.

• Melanesia: the taxon cycle: island faunas as wheels forever turning.

• The Florida Keys: what Darwin and Wallace could only observe, Wilson runs as an experiment.

• The collection: seventy years of specimens at Harvard's MCZ: the primary record itself, with every museum record linked.

• Gorongosa: back to the field at eighty, and the argument for setting aside half the Earth.

Discussion

• Island biogeography predicts extinctions from area alone. What does that imply for nature reserves, and how big is big enough?
• Is Half-Earth an argument from science, from ethics, or both? Where does one end and the other begin?

Classroom logistics

• No accounts. Journal progress saves in the browser, so a voyage can span several sessions on the same device.
• Shared devices: the journal’s “Begin the voyage afresh” link (bottom of the notebook) resets one naturalist’s journal for the next student without touching the others.
• Works on phones and tablets; the panels become bottom sheets, nothing needs a mouse.
• Dotted-underlined terms (endemic, biogeography, uplift…) open plain-language definitions on tap.
• Every port, and every view of the map, has a stable URL you can paste into a lesson plan or LMS.
• By default students sail in order under a fog of war: the map reveals itself port by port, and completing the voyage opens the whole world. A Free-exploration switch on the expedition console lifts the fog for browsing. Your deep links are never locked: a lesson link opens its port directly, wherever the student’s voyage stands.

Standards

The material supports teaching toward NGSS evolution standards: MS-LS4-1/2/4/6 and HS-LS4-1 through HS-LS4-5 (evidence of common ancestry, natural selection, adaptation), and the Wilson unit reaches into LS2 ecosystems and ESS3 human impacts. Formal alignment is a judgment for the teacher; the app’s contribution is the evidence-first sequence and the primary sources.

Primary sources, one click deep

Every rich stop links the naturalist’s own account: the Voyage of the Beagle chapter, the Malay Archipelago chapter, or the very paper written at that stop (the Sarawak Law, the Ternate essay, “On the Monkeys of the Amazon”), all free, via Project Gutenberg and The Alfred Russel Wallace Page.
