Structural Adaptations
Understand that animals have structural adaptations (body features like the giraffe's long neck, eagle's talons, dolphin's streamlined shape), behavioural adaptations (migration, hibernation, tool use), and physiological adaptations (antifreeze in Arctic fish blood, echolocation in bats) — and that these developed over many generations through natural selection

Teaching Table
Set out your lesson
Sort adaptation examples and explain inherited change across generations, not change by wishing.
Describe a camouflage, polar, desert or predator–prey example in your own words. If these are unfamiliar, revisit the hard prerequisite examples before this classification lesson.
Pause and explicitly teach or revisit the named hard prerequisite; do not treat its allocation or authored status as learner readiness.
About 20 minutes. Read cards aloud or on screen; use a pencil and scrap paper if wanted. No animals are handled. Put the category model aside for Try. Supplied examples are source-based cases, not observations made by the learner.
Use the supplied paper cases only unless the optional paper prototype test is explicitly chosen. Do not handle electrical chargers, heat materials, mix chemicals, approach floodwater or volcanoes, or disturb animals. For the optional prototype, an adult checks a clear tabletop; use only paper and a blunt pencil, keep paper away from faces, and stop if the setup feels unsafe. Missing equipment, discomfort or no test means not performed: leave observations blank. No personal health, disaster or family experience is required.
Retain your actual plan and observations on paper between steps. If not performed, leave results blank. Record response mode and assistance; do not infer mastery.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
Antarctic fish example is not mislabelled Arctic.
Do not assume woodpecker anatomy prevents injury; use only the specific adaptation examples supplied.
Simplified natural-selection case does not establish all evolutionary mechanisms.
These bounded source-based examples and task opportunities do not establish learner mastery or general scientific performance.

Check understanding
- Defines adaptation as a feature or behaviour that helps an animal survive in its environment
- Gives examples of structural, behavioural, and physiological adaptations
- Explains that adaptations develop over many generations, not during one animal's lifetime
- Connects adaptations to the concept of natural selection at a basic level
“If your child sees a woodpecker pecking a tree, can they explain that its strong beak, long tongue, and shock-absorbing skull are all adaptations — and describe what the word 'adaptation' means with other examples?”
