Unit 08 · Animal Behavior & Ecology
The year closes by watching animals live — what they do and how they fit together. This unit separates innate behavior, wired in from birth, from learned behavior shaped by experience, and looks at fixed action patterns, the signals animals use to communicate, and how a careful observer records behavior in an ethogram. It then widens the lens to ecology: the niche each species fills, the food webs that link them, how populations rise and fall, and the pressure of predator and prey. Mastery means you can watch an animal, describe what it does without guessing why, and place it in the web of living things around it.
| Criterion | Not yet | Approaching | Mastered |
|---|---|---|---|
| Innate vs. learned behavior | Cannot tell instinct from something the animal learned. | Names the two but mislabels examples. | Distinguishes innate behavior from learned behavior and classifies examples — a spider's web, a bird's learned song — correctly. |
| Fixed action patterns & signaling | Cannot describe a set behavior or the signal that triggers it. | Names a behavior but not the stimulus that releases it. | Identifies a fixed action pattern and the sign stimulus that triggers it, and reads the signals animals use to communicate. |
| Observing & recording behavior | Records interpretations, not observations — says why before what. | Describes behavior but slips into guessing the animal's motives. | Builds an ethogram of observable behaviors, recording what the animal does without assuming why it does it. |
| Ecology (niches, food webs, populations) | Cannot place an animal in a food web or name its niche. | Names a food chain but misses the wider web or the role of a niche. | Maps an animal into its food web, names its niche, and explains how predator-prey pressure shapes populations. |
| Lab technique (field observation) | Skips observation or invents behavior not seen. | Observes but records loosely or reads motives into the data. | Uses field-observation tools to watch and time behavior, records it in a field notebook, and draws conclusions the observations support. |
| 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. |
“A spider spins its web the same way with no chance to learn it — that’s innate, a fixed action pattern. A songbird, though, learns its local song from adults, so that’s learned behavior. In my ethogram I wrote down what each animal did and for how long, and left the ‘why’ out until the data could back it.”
“The animal does stuff because it wants to, I think. Behavior is just instinct. I’m not sure how to write down what it’s doing without saying why.”
You demonstrate this unit through field-observation labs and an ethogram you build yourself — watching real behavior, recording it, and placing an animal in its ecology aloud, not on a multiple-choice test. A criterion counts as mastered only when you can both record what you see and justify the animal biology behind it. Mastery is demonstrated, not awarded.
