Review: Material Design and Comparison
Compare paper model designs against a stated purpose.

Use the skills in a new task
Draw or write four parts for “Material Design and Comparison”—one pretend example from each lesson. In each part, show what happened, give your answer, and say which clue helped you. If the question gives numbers, show your working too. Finish with one thing the practice case does not tell us. You may say your answers aloud.
Work on paper or in your own document. Explain the choices you made.
- Choose one pretend example from each of the four lessons.
- Name what each example shows.
- If the example gives numbers, show your calculation and unit. Otherwise, say which clue explains your answer.
- Say that the case details are supplied for practice; they are not your own real-life observations.
- Say one thing the example does not tell us, or one change that could give a different answer.
Compare with a model response
Panel 1: Which scientific label fits the specifically described step or feature? Supplied case: Bridge must hold a load. Result: strong. Reasoning: The answer is strong. In the notes, it means “holds the stated load.” A material should suit the job. Our test cards provide four properties. Real samples vary; use only the supplied records and keep the reasoning tied to the intended function. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Which scientific label fits the specifically described step or feature? Supplied case: Keep the toy dry. Result: criterion. Reasoning: The answer is criterion. In the notes, it means “desired performance requirement.” Criteria describe what success looks like. Constraints limit materials, size or time. A solution must satisfy essential constraints before preferences can decide between it and another. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 3: Which scientific label fits the specifically described step or feature? Supplied case: Dry dry dry. Result: consistent pass. Reasoning: The answer is consistent pass. In the notes, it means “all supplied runs meet the goal.” Repeated tests reveal whether a result is consistent. A failed run should remain in the record. The supplied tests do not prove performance outside the stated conditions. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 4: Which scientific label fits the specifically described step or feature? Supplied case: Roof misses an outside edge. Result: widen. Reasoning: The answer is widen. In the notes, it means “cover an exposed edge.” Choose a change aimed at the observed failure. Changing everything at once makes it harder to identify the useful change. After revision, compare under matched supplied conditions. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified.
A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
