Flashcard 1: Which option best describes a fair comparison: testing both designs in the same place and time, or in different places?
Answer: Testing both designs in the same place and time. Same conditions ensure differences come from the designs, not the environment.
Flashcard 2: What should stay the same in a fair test when comparing two designs?
Answer: Only one thing changes; the other conditions stay the same. Fair tests require controlling variables except the one being tested.
Flashcard 3: Which option should you change when test results show a design is not meeting the goal?
Answer: Change the part causing the weakness. Fixing the weak part directly addresses the problem.
Flashcard 4: What is a strength of a design when you look at its test results?
Answer: Something the design does well based on the results. Strengths show where the design meets or exceeds expectations.
Flashcard 5: What is a weakness of a design when you look at its test results?
Answer: Something the design does not do well based on the results. Weaknesses reveal areas needing improvement.
Flashcard 6: What does it mean to compare test results from two designs?
Answer: Look at results side by side to see which works better. Examining both outcomes helps identify which performs better.
Flashcard 7: What should you do first if the test results are unclear or confusing?
Answer: Repeat the test the same way. Repeating helps confirm if results are reliable or just random.
Flashcard 8: What does it mean if a design has the same result in repeated tests?
Answer: The result is consistent. Consistent results show the design performs predictably.
Flashcard 9: What does it mean if a design has different results each time it is tested the same way?
Answer: The result is inconsistent. Varying results suggest the design is unreliable.
Flashcard 10: Which option is the best evidence: a single test result or results from many repeated tests?
Answer: Results from many repeated tests. Multiple tests provide stronger evidence than a single test.
Flashcard 11: What is one correct way to record results so two designs are easy to compare?
Answer: Write results in a table with the same units. Tables organize data for easy comparison.
Flashcard 12: What is the best conclusion when one design is stronger in one test but weaker in another?
Answer: Each design has different strengths and weaknesses. No single best design when each excels differently.
Flashcard 13: What does it mean to compare test results from two designs?
Answer: Look at both results to see which design did better. Comparing helps you decide which design works better for your goal.
Flashcard 14: What is a strength of a design when you look at test results?
Answer: A part that works well in the test. Strengths show what the design does successfully.
Flashcard 15: What is a weakness of a design when you look at test results?
Answer: A part that does not work well in the test. Weaknesses show where the design needs improvement.
Flashcard 16: What should you keep the same to make a fair test when comparing designs?
Answer: Only the design changes; everything else stays the same. Fair tests need identical conditions except the design.
Flashcard 17: What is a strength of a design in testing?
Answer: A part that works well and meets the test goal. Strengths show where designs successfully achieve goals.
Flashcard 18: Which tool best helps you compare two designs quickly: a table of results or a story paragraph?
Answer: A table of results. Tables organize data for quick visual comparison.
Flashcard 19: What should you record to compare designs clearly: only the winner or results for both designs?
Answer: Results for both designs. Recording all data allows complete comparison and analysis.
Flashcard 20: What is a weakness of a design in testing?
Answer: A part that does not work well or fails the test goal. Weaknesses show where designs fail to meet objectives.
Flashcard 21: Which option is the best way to compare designs: guess based on looks or use test data?
Answer: Use test data. Data provides objective evidence while guessing is unreliable.
Flashcard 22: Which test result shows a strength: a design that lasts longer or breaks sooner?
Answer: Lasts longer. Longer duration shows better durability and reliability.
Flashcard 23: Which test result shows a strength: a design that holds more weight or less weight?
Answer: Holds more weight. Greater weight capacity indicates stronger structural design.
Flashcard 24: What is the main purpose of comparing test results from two designs?
Answer: To find each design's strengths and weaknesses using evidence. Test results provide objective evidence to evaluate performance.
Flashcard 25: What should you do if results are very close and you are not sure which is better?
Answer: Test again and compare more results. More tests give clearer results for close scores.
Flashcard 26: Choose the word that names the number you measure in a test, like time or distance.
Answer: Result. Results are the measured outcomes of tests.
