Structural Adaptations
结构适应性
Description
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
Mastery Evidence
- 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
Assessment Prompt
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?
