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

• partial: Incredible insects — record-breakers and superpowers. Dung beetles are the strongest animals relative to body weight. Dragonflies are among the fastest flying insects. Fleas can jump over 150 times their own body length. Bombardier beetles spray boiling chemicals. The 'wow factor' of the insect world.

  Bounded objective: Read an insect performance claim with its species and test limits. Only one researched extreme example supplied. Three record-breakers, flea/chemical-temperature claims and scaling-mechanism explanation remain blocked rather than asserted from unverified superlatives.

• partial: Name at least three insect record-breakers and their extreme abilities such as dung beetle strength or flea jumping

  One researched beetle test only, not three verified record-breakers.

• partial: Compare an insect's ability to a human scale, for example a flea's jump would be like a person leaping over a skyscraper

  Hypothetical body-length arithmetic, not a real flea/human equivalence.

• blocked: Explain why being very small helps insects achieve extreme feats of strength or speed relative to their size

  Scaling mechanism not taught; no verified general strength/speed law inferred.

• partial: Can {{name}} tell you about insect record-breakers — like which insect is the world's strongest for its size, or which one can jump the farthest?

  Try offers new-claim-and-scale-application for the bounded objective; it does not establish every part of the source assessment. Only one researched extreme example supplied. Three record-breakers, flea/chemical-temperature claims and scaling-mechanism explanation remain blocked rather than asserted from unverified superlatives.
