Which Design Works Better - 1st Grade Science

1. Which design works better if the goal is to be strongest and A breaks at 5 pulls while B breaks at 7 pulls?

   Design B. 7 pulls before breaking shows more strength than 5 pulls.

2. Which word best completes this claim: "Design A works ___ because it had more successes."?

   better. "Better" shows one design outperformed the other.

3. Which claim matches the data: A goes $7$ cm and B goes $9$ cm, goal is farther; choose A or B?

   Design B. $9$ cm is greater than $7$ cm, so B went farther.

4. Which design works better if Design A takes $12$ seconds and Design B takes $9$ seconds to finish?

   Design B. $9 < 12$ seconds, so B finishes faster.

5. Which design works better if the goal is to go farther and Design A goes 8 steps while Design B goes 10 steps?

   Design B. 10 steps is farther than 8 steps.

6. What is a fair test rule you should follow when comparing two designs?

   Change only one thing and keep the rest the same. Fair testing requires controlling variables.

7. Which reason matches the data: A holds $10$ blocks and B holds $6$ blocks; why is A better?

   It held more blocks in the test. The data shows A held $10$ blocks vs B's $6$ blocks.

8. Which design works better if average distances are A: $9$ cm, B: $9$ cm, and the goal is farther?

   Neither; they are equal. Both traveled $9$ cm, so performance is identical.

9. What is the correct way to finish this claim using data: "Design A works better because it ______"?

   Includes a result number, such as "went farther" or "held more". Must cite specific test results to support claims.

10. Which design works better if the goal is to be faster and Design A takes 12 seconds while Design B takes 9 seconds?

    Design B. 9 seconds is less time than 12 seconds, making B faster.

11. What must stay the same in a fair test when comparing two designs?

    Only the design changes; everything else stays the same. Fair tests control all variables except the design.

12. Which statement is correct: a conclusion should use data or should ignore the data?

    A conclusion should use data. Conclusions must be based on evidence, not opinions.

13. What should you do if the data for Design A and Design B are the same for the goal?

    Conclude they work equally well for that goal. Same results mean both designs perform equally.

14. Which option is the correct evidence statement: "A is better because it held 6 blocks, more than B with 4" or "A is better because I like it"?

    "A is better because it held 6 blocks, more than B with 4.". Uses specific numbers from testing, not personal preference.

15. Choose the best conclusion: A scored $6$ and B scored $6$; which design works better?

    Neither; they work the same based on the data. Equal results mean neither design is better.

16. Which option should you choose if the goal is to hold the most weight?

    Choose the design with the higher weight held. Stronger designs hold more weight without failing.

    Design B. $300$ mL is more than $250$ mL, so B holds more.

22. Which design works better for "fastest": the one with the smaller time or larger time?

    The design with the smaller time. Smaller time means it finished faster, achieving the goal.

23. Which design works better if the goal is to have fewer mistakes and A has 5 errors while B has 2 errors?

    Design B. 2 errors is fewer mistakes than 5 errors.

24. What is data in a design test: recorded results from trials or a guess about results?

    Recorded results from trials. Data consists of actual measurements, not predictions.

25. What must you compare in the data to decide which design works better?

    The results for the same measure (same units and goal). Compare numbers that measure the same thing.

26. What should you do if the data show the two designs have the same result for the goal?

    Say they tie, or that more testing is needed. Equal results mean no clear winner from current data.

27. Which design works better if A breaks $1$ time and B breaks $0$ times (goal: do not break)?

    Design B. B breaks $0$ times, meeting the goal perfectly.
