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: communicate stop visibly. Reference card B: make no sound.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Name the desired message result.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Name the no-noise requirement.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Name the proposed visible card.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Name the planned code check.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: What must the design achieve.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: What restricts the solution.

Learn the idea

A design begins with a need. Our imaginary room needs a quiet visible stop signal. A solution must communicate the message without requiring hearing.

Goal means communicate stop visibly. Constraint means make no sound. Idea means display a red card. Test means ask a reader to use the supplied code.

For goal, look for the clue “communicate stop visibly.” For constraint, look for “make no sound.” 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 “communicate stop visibly”; a second states “make no sound.” The first fits goal and the second fits constraint. 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 “communicate stop visibly” to justify goal; do not sort by the name alone.
  • Distinguish constraint (make no sound) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: Name the desired message result.

goal

The answer is goal. In the notes, it means “communicate stop visibly.” A design begins with a need. Our imaginary room needs a quiet visible stop signal. A solution must communicate the message without requiring hearing.

Take it further

Create one new case showing goal and one showing constraint. Expected: the first explicitly shows “communicate stop visibly”; the second explicitly shows “make no sound.” 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: Name the no-noise requirement.
Need a hint?
  • Look for the described feature: make no sound.
  • 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: Name the proposed visible card.
Need a hint?
  • Look for the described feature: display a red card.
  • 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: Name the planned code check.
Need a hint?
  • Look for the described feature: ask a reader to use the supplied code.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
