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: check consistency of the same design. Reference card B: compare one stated feature.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: One run passed but consistency unknown.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Only fold arrangement should differ.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Want performance under a second load condition.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Known gap causes failure.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Check the same bridge a second time.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Keep sheets fixed while changing folds.

Learn the idea

Testing should address an unresolved performance question. A new design change needs fresh evidence. Keep the material budget fixed if comparing arrangements rather than materials.

Repeat means check consistency of the same design. Matched compare means compare one stated feature. New condition means check an additional stated challenge. Redesign means change a failing feature before testing.

For repeat, look for the clue “check consistency of the same design.” For matched compare, look for “compare one stated feature.” 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 “check consistency of the same design”; a second states “compare one stated feature.” The first fits repeat and the second fits matched compare. 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 “check consistency of the same design” to justify repeat; do not sort by the name alone.
  • Distinguish matched compare (compare one stated feature) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: One run passed but consistency unknown.

repeat

The answer is repeat. In the notes, it means “check consistency of the same design.” Testing should address an unresolved performance question. A new design change needs fresh evidence. Keep the material budget fixed if comparing arrangements rather than materials.

Take it further

Create one new case showing repeat and one showing matched compare. Expected: the first explicitly shows “check consistency of the same design”; the second explicitly shows “compare one stated feature.” 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.

1. Which scientific label fits the specifically described step or feature? Supplied case: Only fold arrangement should differ.
Need a hint?
  • Look for the described feature: compare one stated feature.
  • 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: Want performance under a second load condition.
Need a hint?
  • Look for the described feature: check an additional stated challenge.
  • 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: Known gap causes failure.
