Comparing Design Strengths - 1st Grade Science

1. Which design is more accurate if Design A hits the target $8$ times and Design B hits $6$ times?

   Design A. $8 > 6$ hits shows Design A has better accuracy.

2. Which option is the best evidence: a single test result or results from many repeated tests?

   Results from many repeated tests. Multiple tests provide stronger evidence than a single test.

3. Which design is more consistent if A gets $10, 10, 10$ and B gets $6, 12, 9$ in the same test?

   Design A. A's identical results show better consistency than B's varied results.

4. Which design improved if its results changed from 4 to 7 in the next test?

   The design that changed from 4 to 7 improved. Higher scores show the design got better.

5. Which design meets the goal if the goal is at least 6 points: A = 6, B = 5?

   Design A. Design A equals the goal; B falls short.

6. What does it mean if a design has the same result in repeated tests?

   The result is consistent. Consistent results show the design performs predictably.

7. Which test result shows better performance: 10 cm traveled or 6 cm traveled?

   10 cm traveled. Greater distance shows better movement ability.

8. What is one correct way to record results so two designs are easy to compare?

   Write results in a table with the same units. Tables organize data for easy comparison.

9. Which design is faster if Design A finishes in $12$ seconds and Design B finishes in $9$ seconds?

   Design B. $9 < 12$ seconds means Design B completes faster.

10. What is a strength of a design when you look at test results?

    A part that works well in the test. Strengths show what the design does successfully.

11. What should you keep the same to make a fair test when comparing designs?

    Only the design changes; everything else stays the same. Fair tests need identical conditions except the design.

12. Which test result shows a strength: a design that lasts longer or breaks sooner?

    Lasts longer. Longer duration shows better durability and reliability.

13. What should you record to compare designs clearly: only the winner or results for both designs?

    Results for both designs. Recording all data allows complete comparison and analysis.

14. Which option best describes a fair comparison: testing both designs in the same place and time, or in different places?

    Testing both designs in the same place and time. Same conditions ensure differences come from the designs, not the environment.

15. Which option shows a fair test: change the ramp height for one design only, or keep ramp height the same for both?

    Keep ramp height the same for both. Equal conditions ensure only the design differences affect results.

16. Identify the best conclusion if Design A works $8$ times out of $10$ and Design B works $5$ times out of $10$.

    Design A is more reliable than Design B. Design A succeeds more often, making it more dependable.

17. Which design is stronger if Design A holds $10$ blocks and Design B holds $7$ blocks?

    Design A. $10 > 7$, so Design A can support more weight.

18. Identify the strength if a boat design floats for a long time without leaking.

    Floats a long time without leaking. Long floating time shows good design success.

19. What is a strength of a design in testing?

    A part that works well and meets the test goal. Strengths show where designs successfully achieve goals.

20. What does it mean to compare test results from two designs?

    Look at both results to see which design did better. Comparing helps you decide which design works better for your goal.

21. Identify the strength if a parachute design falls slowly and lands without breaking the object.

    It protects the object by slowing the fall. Slow descent prevents damage, achieving the protection goal.

22. Identify the weakness if a bridge design holds many coins but bends a lot.

    Bends too much. Too much bending shows structural weakness.

23. Which tool best helps you compare two designs quickly: a table of results or a story paragraph?

    A table of results. Tables organize data for quick visual comparison.

24. Which test result shows a strength: a design that holds more weight or less weight?

    Holds more weight. Greater weight capacity indicates stronger structural design.

25. What is the best conclusion when one design is stronger in one test but weaker in another?

    Each design has different strengths and weaknesses. No single best design when each excels differently.

26. What should you do first if the test results are unclear or confusing?

    Repeat the test the same way. Repeating helps confirm if results are reliable or just random.

27. What does it mean if a design has different results each time it is tested the same way?

    The result is inconsistent. Varying results suggest the design is unreliable.

28. What is a weakness of a design when you look at test results?

    A part that does not work well in the test. Weaknesses show where the design needs improvement.

29. Identify the stronger design if Design A has 2 breaks and Design B has 0 breaks.

    Design B. No breaks means the design is more durable.

30. What is a strength of a design when you look at its test results?

    Something the design does well based on the results. Strengths show where the design meets or exceeds expectations.

31. What should you do if results are very close and you are not sure which is better?

    Test again and compare more results. More tests give clearer results for close scores.

32. Choose the word that names the number you measure in a test, like time or distance.

    Result. Results are the measured outcomes of tests.

33. Which option should you change when test results show a design is not meeting the goal?

    Change the part causing the weakness. Fixing the weak part directly addresses the problem.

34. Which design is better if the goal is fastest time: A = 12 s, B = 9 s?

    Design B. Lower time means faster completion.

35. What should stay the same in a fair test when comparing two designs?

    Only one thing changes; the other conditions stay the same. Fair tests require controlling variables except the one being tested.

36. Identify the weakness if a bridge design holds $3$ books but the goal is to hold $5$ books.

    It does not hold enough weight. The bridge fails to meet the $5$-book requirement.

37. Identify the better choice if the goal is the longest distance: Design A goes $9$ m and Design B goes $11$ m.

    Design B. $11$ m exceeds $9$ m, meeting the distance goal better.

38. Which design is stronger if Design A holds $6$ blocks and Design B holds $4$ blocks before breaking?

    Design A. Design A supports more blocks before failing.

39. What is a weakness of a design when you look at its test results?

    Something the design does not do well based on the results. Weaknesses reveal areas needing improvement.

40. Which test result shows better performance: 3 leaks or 1 leak?

    1 leak. Fewer leaks means better waterproofing.

41. Which design has the weakness if it breaks during the test while the other design does not break?

    The design that breaks. Breaking indicates structural failure, a clear weakness.

42. Which design is more consistent if A scores 5, 5, 5 and B scores 2, 6, 7?

    Design A. Same scores each time show reliable performance.

43. What is the main purpose of comparing test results from two designs?

    To find each design's strengths and weaknesses using evidence. Test results provide objective evidence to evaluate performance.

44. Which design has the higher success rate: Design A $\frac{7}{10}$ or Design B $\frac{6}{10}$?

    Design A. $\frac{7}{10} > \frac{6}{10}$, so A succeeds more frequently.

45. Identify the stronger design if Design A holds 7 coins and Design B holds 4 coins.

    Design A. More coins held shows greater strength.

46. What does it mean to compare test results from two designs?

    Look at results side by side to see which works better. Examining both outcomes helps identify which performs better.

47. Which design is better if the goal is longest time: A = 15 s, B = 11 s?

    Design A. Higher time means it lasts longer.

48. Which design is faster if Design A finishes in $12$ seconds and Design B finishes in $15$ seconds?

    Design A. Lower time means faster completion.

49. What is a weakness of a design in testing?

    A part that does not work well or fails the test goal. Weaknesses show where designs fail to meet objectives.

50. Which test result shows better performance: 8 blocks held or 5 blocks held?

    8 blocks held. More blocks held means stronger support.

51. Which design meets a goal of at least $6$ blocks if Design A holds $6$ and Design B holds $5$?

    Design A. Design A meets the $6$ block minimum; Design B falls short.

52. Which design is better for a goal of being light if Design A is $30$ g and Design B is $20$ g?

    Design B. $20 < 30$ grams, so Design B is lighter.

53. Which design best meets the goal if the goal is "no leaks": A leaks $0$ drops, B leaks $3$ drops?

    Design A. Zero leaks perfectly meets the no-leak requirement.

54. Which option is the best way to compare designs: guess based on looks or use test data?

    Use test data. Data provides objective evidence while guessing is unreliable.
