Supplied materials

  • All measurements and observations below are supplied classroom examples. They are not data from actual learners or a claim about a particular real site.
  • Paper, drawing space or a browser document.
  • Reference card A: hold the stated model load. Reference card B: use no more than the stated sheets.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Required load capacity.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Maximum sheet count.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Preferred color.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Observed model result.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Bridge must hold four counters in record.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Only three paper sheets allowed.

Learn the idea

Criteria define desired performance and constraints set limits. A preference is optional unless made essential. Our paper bridge has a load goal and fixed material budget.

Criterion means hold the stated model load. Constraint means use no more than the stated sheets. Preference means look attractive after essentials are met. Evidence means recorded load test result.

For criterion, look for the clue “hold the stated model load.” For constraint, look for “use no more than the stated sheets.” 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 “hold the stated model load”; a second states “use no more than the stated sheets.” The first fits criterion 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.

Check your reasoning

Your answer is temporary and is not saved to an account. Download your current answer before leaving or reloading. Written work on paper or in another app stays in your own file.

Helpful tips
  • Use the feature “hold the stated model load” to justify criterion; do not sort by the name alone.
  • Distinguish constraint (use no more than the stated sheets) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: Required load capacity.

See the answer and explanation

criterion

The answer is criterion. In the notes, it means “hold the stated model load.” Criteria define desired performance and constraints set limits. A preference is optional unless made essential. Our paper bridge has a load goal and fixed material budget.

Take it further

Create one new case showing criterion and one showing constraint. Expected: the first explicitly shows “hold the stated model load”; the second explicitly shows “use no more than the stated sheets.” 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: Maximum sheet count.
Need a hint?
  • Look for the described feature: use no more than the stated sheets.
  • 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: Preferred color.
Need a hint?
  • Look for the described feature: look attractive after essentials are met.
  • 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: Observed model result.
