Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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