This packet is everything a parent or guide needs to assess Unit 05 at home — learning targets, the answers that count as correct, the mastery rubric, calibration examples, and a clipboard score sheet. No multiple-choice test: the student shows mastery by running a natural-selection simulation and explaining how a population changes over time aloud.
By the end of the Evolution & Adaptation unit, a student should be able to:
Six criteria, each judged Not yet / Approaching / Mastered (Page 3).
Run the activity; track what survives and breeds each round.
The student explains how the population changed and why (Page 4).
Each round's survivors, the pattern, and the conclusion kept distinct.
You are making a decision, not adding up points. For each criterion, decide whether the work is Not yet, Approaching, or Mastered — the column language tells you which. A criterion counts as mastered only when the student can both run the activity and explain the biology behind it. A student carries three tokens per term; one token buys a re-do of one criterion on another day, so a single bad afternoon never sinks the unit.
Accept any answer in the synonyms column — they are pre-approved as equivalent. The third column flags the confusions that look close but are not yet, so you can coach precisely.
| Canonical answer | Accepted synonyms | Common confusion / discriminator |
|---|---|---|
| Adaptation & survival | ||
| Adaptation | helpful trait | A feature that helps an organism survive and reproduce — not something it chooses to grow |
| Variation | natural differences | Small differences between members of one species; the raw material selection works on |
| Environment | habitat, surroundings | The living and non-living things an organism must survive among |
| Survival & reproduction | living long enough to have young | Selection is not just surviving — it is passing traits to the next generation |
| Change over time | ||
| Natural selection | survival of the fittest | Variation + survival + reproduction over many generations; no one changes their own body on purpose |
| Fossil | preserved remains or trace | Evidence of past life; shows how living things have changed over long times |
| Tree of life | branching diagram | Evolution branches like a tree — not a ladder from “lower” to “higher” |
| Species | one kind of organism | A group whose members can breed and produce offspring like themselves |
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Adaptations & survival | Thinks an animal changes its own body on purpose to fit in. | Names an adaptation but can’t say how it helps survival. | Explains how an adaptation helps an organism survive and reproduce in its environment. |
| Variation within a species | Thinks all members of a species are exactly the same. | Notices differences but doesn’t connect them to survival. | Explains how natural differences within a species can make some individuals more likely to survive. |
| Natural selection | Believes traits an animal builds in its lifetime get passed on. | Describes survival of the fittest but skips reproduction or time. | Explains natural selection — variation, survival, and reproduction over many generations. |
| Evidence & the tree of life | Pictures evolution as a ladder from “lower” to “higher” animals. | Uses fossils as evidence but still ranks species as more or less advanced. | Uses fossils and shared traits as evidence and describes evolution as a branching tree. |
| Lab technique (natural-selection simulation) | Runs the simulation without tracking what survives. | Collects data but can’t explain the pattern it shows. | Runs a natural-selection simulation, records each round, and explains how the population changed. |
| Integration (cross-domain) | Treats the science as isolated facts; makes no cross-domain connection. | Names a link to history, reading, or writing but cannot defend why it matters. | Connects the unit to its anchor across History · Reading · Writing (plus chosen electives) and defends why the connection matters. |
The split between Approaching and Mastered is the mechanism is there: real evolution needs survival and reproduction over many generations. Ask “who survived and had more offspring, and did that trait get more common?”
Read these before you grade. They show what Mastered and Not yet actually sound like, plus the edge cases where you should coach rather than decide on the spot.
