Structures for Survival
Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction

Teaching Table
Set out your lesson
Link a structure to a function with a reason.
Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.
Check readiness rather than assuming source graph order establishes attainment.
Use provided organism feature cards; no specimen handling.
Use the supplied stage cards on screen or scrap paper; adult key stays separate.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behaviour, and reproduction
Bounded objective: Link a structure to a function with a reason. Selected structures only; reproduction-specific example not assessed.
- partial: Give examples of external structures and their survival functions (e.g. thorns for protection, claws for catching prey)
Thorn/claw examples with mechanisms provided.
- partial: Give examples of internal structures and their functions (e.g. heart pumps blood, lungs take in air)
Heart/lung functions supplied as internal examples.
- partial: Construct a reasoned argument linking a specific structure to how it helps the organism survive or reproduce
Webbed-foot movement argument supported by supplied mechanism; reproduction example absent.
- partial: Can {{name}} explain how a cactus's thick stem helps it survive in a desert, or how a bird's wings help it find food?
Try offers new-supplied-evidence-argument for the bounded objective; it does not establish every part of the source assessment. Selected structures only; reproduction-specific example not assessed.

Check understanding
- Give examples of external structures and their survival functions (e.g. thorns for protection, claws for catching prey)
- Give examples of internal structures and their functions (e.g. heart pumps blood, lungs take in air)
- Construct a reasoned argument linking a specific structure to how it helps the organism survive or reproduce
“Can your child explain how a cactus's thick stem helps it survive in a desert, or how a bird's wings help it find food?”
