Supplied materials

  • For younger learners, an adult may read each direction aloud; pointing, drawing and spoken explanations count as responses.
  • Paper, drawing space or a browser document.
  • Reference card A: helps the supplied bird fly. Reference card B: helps the supplied animal walk.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Bird lifts using feathered limb.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Cat moves using walking limb.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Turtle has protective outer structure.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Fish extracts oxygen from water.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Bird’s flight limb.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Fish’s water-breathing structure.

Learn the idea

Body parts perform functions. These supplied descriptions tell you what a part does for a named animal. The same-looking part need not do exactly the same job in every species.

Wing means helps the supplied bird fly. Leg means helps the supplied animal walk. Shell means protects the supplied turtle. Gill means helps the supplied fish take oxygen from water.

For wing, look for the clue “helps the supplied bird fly.” For leg, look for “helps the supplied animal walk.” More than one process can happen in a real situation. Answer about the one described in this question.

  1. Read or listen to the four science words and what each means. Say how the first two differ.
  2. Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
  3. Answer each practice question. Say which clue helped you, then check the explanation.
  4. Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.
Worked example

See the method in action

Worked reference-card problem: a card states “helps the supplied bird fly”; a second states “helps the supplied animal walk.” The first fits wing and the second fits leg. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips
  • Use the feature “helps the supplied bird fly” to justify wing; do not sort by the name alone.
  • Distinguish leg (helps the supplied animal walk) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: Bird lifts using feathered limb.

See the answer and explanation

wing

The answer is wing. In the notes, it means “helps the supplied bird fly.” Body parts perform functions. These supplied descriptions tell you what a part does for a named animal. The same-looking part need not do exactly the same job in every species.

Take it further

Create one new case showing wing and one showing leg. Expected: the first explicitly shows “helps the supplied bird fly”; the second explicitly shows “helps the supplied animal walk.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

More practice: try new cases

Choose an answer for each problem. Explain your method on paper, then use the feedback to decide what to revisit.

More practice: try new cases
1. Which scientific label fits the specifically described step or feature? Supplied case: Cat moves using walking limb.
Need a hint?
  • Look for the described feature: helps the supplied animal walk.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
2. Which scientific label fits the specifically described step or feature? Supplied case: Turtle has protective outer structure.
Need a hint?
  • Look for the described feature: protects the supplied turtle.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
3. Which scientific label fits the specifically described step or feature? Supplied case: Fish extracts oxygen from water.
Need a hint?
  • Look for the described feature: helps the supplied fish take oxygen from water.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
