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: detecting the supplied sound. Reference card B: detecting the supplied visible change.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Bird reacts to a call.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Animal notices a moving shape.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Whisker contacts an obstacle.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Dog notices a food odor.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Rabbit reacts to a noise.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Cat notices gentle contact.

Learn the idea

Animals gather information using senses and can respond. A stimulus is a change that can be detected. We analyze fictional observations, not an individual’s medical condition.

Hearing means detecting the supplied sound. Seeing means detecting the supplied visible change. Touch means detecting the supplied contact. Smell means detecting the supplied airborne odor.

For hearing, look for the clue “detecting the supplied sound.” For seeing, look for “detecting the supplied visible change.” 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 “detecting the supplied sound”; a second states “detecting the supplied visible change.” The first fits hearing and the second fits seeing. 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 “detecting the supplied sound” to justify hearing; do not sort by the name alone.
  • Distinguish seeing (detecting the supplied visible change) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: Bird reacts to a call.

See the answer and explanation

hearing

The answer is hearing. In the notes, it means “detecting the supplied sound.” Animals gather information using senses and can respond. A stimulus is a change that can be detected. We analyze fictional observations, not an individual’s medical condition.

Take it further

Create one new case showing hearing and one showing seeing. Expected: the first explicitly shows “detecting the supplied sound”; the second explicitly shows “detecting the supplied visible change.” 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: Animal notices a moving shape.
Need a hint?
  • Look for the described feature: detecting the supplied visible change.
  • 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: Whisker contacts an obstacle.
Need a hint?
  • Look for the described feature: detecting the supplied contact.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
