Design Success Criteria - 3rd Grade Science

1. Which success criterion focuses on safety: "sharp edges allowed" or "no sharp edges"?

   No sharp edges. Safety criteria prevent harm from the design.

2. Which option is a constraint, not a success criterion: "Use only $10$ straws" or "Must float"?

   Use only $10$ straws. Material limits are constraints; performance goals are criteria.

3. Which option is a success criterion: "Looks nice" or "Holds 10 books without bending"?

   Holds 10 books without bending. Specific numbers make it testable, unlike subjective qualities.

4. What is the purpose of success criteria before building a design?

   To guide building and provide a way to judge success. Criteria help plan designs and evaluate if they work.

5. Which option is a constraint, not a success criterion: "Use only 5 straws" or "Stands for 10 seconds"?

   Use only 5 straws. Constraints limit resources; criteria define success.

6. What is the difference between a goal and a success criterion?

   A goal is broad; a success criterion is specific and testable. Goals are general aims; criteria have specific, measurable targets.

7. What is one required feature of a good success criterion in science?

   It is observable and testable. Good criteria can be measured through observation or testing.

8. What should a success criterion connect to in the problem statement?

   The user need or goal described in the problem. Criteria should address the problem's requirements.

9. Choose the criterion that is testable: "strong" or "supports 1 book for 10 seconds."

   Supports 1 book for 10 seconds. "Strong" is vague; specific weight and time are measurable.

10. Which option is a complete success criterion: "Works well" or "Stops a marble within $10$ cm"?

    Stops a marble within $10$ cm. Distance measurement is specific; "works well" is vague.

11. Which option is a constraint: "works well" or "uses only 10 straws"?

    Uses only 10 straws. Constraints set specific limits; "works well" is too vague.

12. Identify the best success criterion for a paper bridge: "Looks good" or "Holds $20$ pennies"?

    Holds $20$ pennies. Weight capacity is measurable; appearance is subjective.

16. Which option describes a measurable success criterion: "It looks nice" or "It holds 10 books"?

    "It holds 10 books". Numbers make it measurable; "nice" is subjective.

17. What is the best type of statement for a success criterion: opinion or testable fact?

    Testable fact. Facts can be tested objectively; opinions cannot be measured.

18. Which tool is best for checking success criteria: a guess or a test?

    A test. Tests provide objective evidence; guesses are unreliable.

19. Which word best describes success criteria: vague or specific?

    Specific. Success criteria need exact details to be properly tested.

20. What is the best way to write a success criterion for strength?

    State an exact load, such as "holds 50 grams.". Weight measurements make strength testable and comparable.

21. What does it mean if a design meets all success criteria?

    It is considered successful for that problem. Meeting all criteria means the solution works as intended.

22. What does it mean if a success criterion is measurable?

    You can test it and tell if it is met. Measurable means you can observe and verify if it's achieved.

23. What is a fair way to compare two designs using success criteria?

    Test both the same way and score them using the same criteria. Equal testing conditions ensure valid comparison.

24. Which option is a criterion: "use only recycled paper" or "keeps water from leaking"?

    "Keeps water from leaking". Preventing leaks is a performance goal, not a limitation.

    It can be checked with numbers or clear observations. Quantifiable results allow objective evaluation.

26. What does it mean if a success criterion is measurable?

    You can test it and record results with observations or numbers. Measurable means you can collect data to verify success.

27. What is a fair way to compare two designs using criteria for success?

    Test both the same way and compare results to the criteria. Fair comparison requires identical testing conditions.

    "Holds $2$ kg without breaking". Exact weight gives clear, testable target.

49. Identify the vague criterion: "works well" or "moves $1$ m in $5$ s"?

    "Works well". "Well" can't be measured objectively.

50. What should you do if test results show a design does not meet a success criterion?

    Improve the design and test again. Engineering involves iterative improvement.

51. What is the main purpose of success criteria in an engineering design process?

    To decide if a design meets the problem needs. Criteria help evaluate if the solution solves the problem.

52. What should you do if a success criterion cannot be tested?

    Rewrite it so it is specific and measurable. Vague criteria must be clarified to enable testing.

53. What is the difference between a goal and a success criterion?

    Goal is broad; criterion is specific and testable. Goals are general desires; criteria are measurable benchmarks.

54. Identify the best success criterion for a paper bridge: "Strong" or "Holds 20 pennies"?

    Holds 20 pennies. Numbers (20 pennies) are measurable; "strong" is vague.

55. What is one way to write a strong success criterion for a design?

    Include a specific performance measure, such as a number and unit. Numbers and units create measurable, testable criteria.

56. Identify the problem with this criterion: "The car is awesome."

    It is an opinion and not measurable. "Awesome" is subjective and cannot be objectively tested.

57. What is a constraint in a science design challenge?

    A limit such as time, materials, size, or cost. Constraints restrict what you can use or do in your design.

58. Which option is the clearest success criterion: "Does not leak" or "Leaks less than 1 drop in 1 minute"?

    Leaks less than 1 drop in 1 minute. Quantifying leaks allows objective pass/fail testing.

59. What does it mean if a success criterion is specific?

    It clearly states exactly what the design must do. Specific criteria leave no room for interpretation.

60. What is a criterion (not a constraint) in a design problem?

    A feature the design must achieve to be successful. Criteria define what the design must accomplish to succeed.

61. What is a success criterion in a science design task?

    A clear statement that tells what the design must do to be successful. Success criteria define specific, measurable outcomes for design solutions.

62. Which option is a constraint: "must be safe" or "must cost under $5$"?

    "Must cost under $5$". Cost limit is a restriction, not a goal to achieve.

63. What should success criteria be based on: the problem needs or personal preferences?

    The problem needs. Criteria must address the actual problem, not wants.

64. Identify the measurable part of this criterion: "The bridge holds 20 coins."

    Holds 20 coins. The number "20 coins" makes this criterion testable.

65. Which option is a success criterion for a parachute: "Falls slowly" or "Takes at least $3$ s to land"?

    Takes at least $3$ s to land. Time measurement is specific; "slowly" is subjective.

    Measurable requirements. Success criteria must be quantifiable, not based on opinions.

67. What does it mean if a criterion is testable?

    You can check it by doing a fair test and observing results. Testable means you can verify it through experiments.

68. What is the purpose of success criteria in designing and testing a solution?

    To judge whether the solution meets the problem requirements. Criteria help evaluate if designs solve the problem.

69. What is the difference between a goal and a success criterion?

    Goal is broad; criterion is a checkable requirement. Goals are general desires; criteria are specific, testable requirements.

70. What is the main purpose of listing criteria for success before building a design?

    To know how the design will be judged and tested. Criteria guide the design process and evaluation methods.

71. Find the success criterion: "Must be safe and use only tape; should protect an egg from 30 cm."

    Protect an egg from 30 cm. This is the measurable outcome to test, not a constraint.

72. Which option is a performance criterion: "is blue" or "floats for $10$ minutes"?

    "Floats for $10$ minutes". Time duration measures performance; color doesn't.

73. Which statement is a complete success criterion: "Be stable" or "Stand upright for 60 seconds without falling"?

    Stand upright for 60 seconds without falling. Includes what, how long, and failure condition for testing.
