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.
