EvoLab: Teacher Manual

1. The first ten minutes

EvoLab opens on Evolution Mission Control, which is deliberately not a menu of seventeen things. It offers one starting path — Variation to selection — and says why: "begin with a visible cause-and-effect sequence before opening the whole catalog."

Take that advice on day one.

1. Press Start path. The recommended sequence is three modules: Predator Vision, Selection Sandbox, Galápagos Beak Lab.
2. Predator Vision first, and say the framing out loud: you are the selection pressure. The student hunts, and their own choices change the population. Nothing about evolution is abstract after that.
3. Selection Sandbox second. Now the student watches a population evolve under a pressure they set rather than one they apply by hand.
4. Galápagos Beak Lab third — real Grant finch data. This is the move that converts a simulation into science: the pattern they just produced artificially shows up in field measurements from a real island.

That three-module sequence is a complete first lesson, and the order matters: cause you apply → cause you set → cause observed in nature. Students who do it in that order tend not to describe evolution as something that "wants" to happen.

2. The five-step loop that holds the unit together

Mission Control shows the mechanism as five numbered steps, and every module is an instance of it. Put these five on your board for the whole unit:

The pedagogical value is in step 5 being about the group. The single most durable misconception in this topic is that individuals evolve — that a finch grows a bigger beak because it needs one. A student who can name all five steps in order has the structure that makes that claim impossible.

After a lab, ask students to say which of the five steps they just watched. It takes fifteen seconds and it is the best formative check in the unit.

3. Four paths, seventeen modules

The modules are grouped into four paths. You can teach a path as a unit, or switch paths freely — the tool does not lock them.

The full catalogue, browsable from Browse every EvoLab module, includes: Predator Vision, Mate Choice Lab, Climate Pressure Lab, Selection Sandbox, Galápagos Beak Lab, Trait Divergence Model, Phylogenetic Tree Builder, Hardy-Weinberg, Genetic Drift, Common Ancestry, Antibiotic Resistance, Coevolution Lab, Discovery Timeline, Misconceptions Quiz, Selection Sleuth, Homology vs Analogy, and the Capstone Project.

Three modules teachers consistently underuse. Antibiotic Resistance is the one students already care about and the cleanest real-world selection story. Homology vs Analogy fixes a comparison error that otherwise survives into high school biology. Genetic Drift is the antidote to "evolution is always adaptive" — change with no selection at all.

4. How completion is earned

The dashboard tracks four counters: Completed (of 17), Explored (of 17), Experiments, and Challenges (of 41).

The distinction is worth explaining to students, because it is unusually honest. The tool states that completion is earned by doing — finishing a hunt, running 20 generations, grading a tree, or finishing a quiz. Opening a module marks it explored, not complete. "Experiments" are the "Try this" cards inside each module.

So a student cannot clear the board by clicking through. For grading, "completed" is the number that means something; "explored" tells you where they went.

5. Three classroom walkthroughs

A. Natural selection in one period (grades 6–8)

1. Everyone runs Predator Vision to the first challenge (the suggested one is "90% camouflage by round 8").
2. Stop the class. On the board, map what happened onto the five loop steps. Students will have applied steps 2 and 3 themselves.
3. Selection Sandbox, 20 generations, with a written prediction first: which trait becomes common, and why?
4. Exit ticket via 🎟️ Exit Tickets, or have students write the loop from memory.

B. Simulation versus real data (grades 9–12)

1. Selection Sandbox: produce a directional shift and record the generation count.
2. Galápagos Beak Lab: work through the Grant data.
3. The discussion question: "our simulation shifted in 20 generations; the finches shifted in a few years. What does that tell you about how fast selection can act when the pressure is severe?"
4. Hardy-Weinberg to formalise it — what would no change look like, and why is that the null hypothesis?
5. Genetic Drift to complicate it: change without selection. Ask which of the two explains a small island population better.

C. Tree of life as evidence (grades 8–12)

1. Homology vs Analogy first — students must be able to tell shared ancestry from convergent solutions before a tree means anything.
2. Common Ancestry, then Phylogenetic Tree Builder, where they build and get a tree graded.
3. Selection Sleuth as the reasoning challenge.
4. Finish with the Capstone Project, which is the natural summative assessment for the unit.

6. The teacher surfaces

Four things sit under Teacher Resources, and the first is the reason to read this section.

📊 Class Snapshot

Students copy their journal as text; you paste those into the Snapshot and it shows who finished what, which predictions held, the most common wrong first answers on each check, and every field note by module.

That middle item is the one worth planning a lesson around. A list of the most common wrong first answers in your class is a better discussion agenda than anything a textbook provides. The tool states plainly that this runs in the page and nothing is uploaded.

📅 5-Day Curriculum Guide

Five 50-minute periods sequencing all modules into a unit, each day with a warm-up, lab activity, class discussion and exit ticket. Module links inside the guide launch the module directly, and it is print-friendly.

If you have a week for evolution, start here rather than building your own sequence. The walkthroughs above are for fitting EvoLab into a shorter slot.

Standards Crosswalk and Module Map

The crosswalk maps modules to standards for planning documents; the Module Map is the overview of all 17 at a glance. Both are useful for a department meeting or an administrator asking what a week on this tool covers.

7. The misconceptions this tool targets

EvoLab has an entire module for these (Misconceptions Quiz), which tells you how central they are to the design. The four worth pre-empting:

"Individuals evolve."

Step 5 of the loop is explicitly about the group changing over generations. A finch does not grow a bigger beak; the distribution of beaks in the population shifts.

"Evolution has a goal, or organisms evolve what they need."

Predator Vision makes the student the pressure, so the direction of change is visibly a consequence of an external condition, not an aspiration. Genetic Drift then shows change with no pressure at all.

"Traits acquired in a lifetime get passed on."

Step 4 — inheritance — is a separate numbered step for exactly this reason. The population-genetics path makes the mechanism explicit.

"Evolution is too slow to observe."

Galápagos Beak Lab is measured field data over a few years, and Antibiotic Resistance happens on a timescale students have personally lived through.

8. Where student work lives

Progress and journal entries are kept on the student's own device, in the browser. There is no account and no sign-in. Two consequences to plan for:

• A different device means a fresh start. If students rotate machines, have them copy their journal (📓 My journal) as text at the end of each session — which is also exactly what Class Snapshot consumes.
• Clearing browser data clears progress. Worth saying before a multi-day unit on shared laptops.

The Class Snapshot's paste-in design follows from this: it is how a teacher aggregates without the tool ever collecting anything centrally.

9. When something looks wrong

A student's module count is not going up.

Opening a module marks it explored. Completion requires finishing the activity — a hunt, 20 generations, a graded tree, a quiz. See section 4.

Seventeen modules is overwhelming for my class.

Use the recommended path (three modules) or the 5-Day Guide. Mission Control's design assumes you will not open the whole catalogue on day one.

Class Snapshot shows nothing after I paste.

It reads the journal text students copy from 📓 My journal. A screenshot or a hand-typed summary will not parse.

Two students ran the same simulation and got different results.

Expected, and a teaching opportunity. Selection acts on a population with random variation; drift especially is stochastic. Run it several times and discuss the distribution rather than the single outcome.
