These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

• partial: Describe the structure and four main functions of the human skeleton: support, protection, movement, and production of blood cells in bone marrow

  Bounded objective: Connect skeleton parts with support, protection, movement and blood-cell production. Schematic/functions only; detailed bone identification and real anatomical observation not established.

• partial: Lists and explains the four functions of the skeleton with examples

  Support/protection/movement/marrow production functions recalled.

• partial: Names key bones and identifies which organs they protect (e.g. ribcage protects heart and lungs)

  Skull/brain and ribs/chest linked; selected bones only.

• partial: Explains what bone marrow is and where blood cells are made

  Marrow blood-cell role taught; tissue detail not assessed.

• partial: If {{name}} was asked why we have bones, could they explain that bones do more than just hold us up — describing at least three different things the skeleton does for the body?

  Try offers taught-content-recall for the bounded objective; it does not establish every part of the source assessment. Schematic/functions only; detailed bone identification and real anatomical observation not established.
