Flashcard 1: Which design works better if the goal is most successful trials and A succeeded 7 times while B succeeded 5 times?
Answer: Design A. 7 successes is more than 5 successes.
Flashcard 2: Which word best completes this claim: “Design A works because it had more successes.”?
Answer: better. "Better" shows one design outperformed the other.
Flashcard 3: Identify the evidence part in this sentence: “Design B is better because it held 8 cubes.”
Answer: “it held 8 cubes”. Evidence is the specific measurement, not the opinion.
Flashcard 4: Identify the missing part: “Design B is better because .” What must fill the blank?
Answer: A measured number from the data (with units if used). Claims need specific data to support them.
Flashcard 5: Which sentence uses evidence correctly: “A is better” or “A is better because it went 4 cm farther”?
Answer: “A is better because it went 4 cm farther.”. Good claims include both opinion and supporting data.
Flashcard 6: What should you do if the data show the two designs have the same result for the goal?
Answer: Say they tie, or that more testing is needed. Equal results mean no clear winner from current data.
Flashcard 7: What must stay the same in a fair test when comparing two designs?
Answer: Only the design changes; everything else stays the same. Fair tests control all variables except the design.
Flashcard 8: What is the correct comparison word when A has 3 and B has 8 for a “less is better” goal?
Answer: A has less than B. 3 is less than 8.
Flashcard 9: What is the correct comparison word when A has 9 and B has 6 for a “more is better” goal?
Answer: A has more than B. 9 is greater than 6.
Flashcard 10: Choose the best conclusion: A scored 6 and B scored 6; which design works better?
Answer: Neither; they work the same based on the data. Equal results mean neither design is better.
Flashcard 11: What is the best design when the goal is to get the smallest result (for example, least time)?
Answer: The design with the smallest measured value. Compare numbers and pick the lowest one.
Flashcard 12: Which design works better if the goal is least time and A took 6 s while B took 8 s?
Answer: Design A. 6 s is less than 8 s, so A was faster.
Flashcard 13: Which design works better if the goal is farthest distance and A went 9 cm while B went 11 cm?
Answer: Design B. 11 cm is greater than 9 cm, so B went farther.
Flashcard 14: Which option is evidence (not a claim): “Design B went farther” or “Design B went 12 cm”?
Answer: “Design B went 12 cm”. Evidence includes specific numbers with units.
Flashcard 15: Which option is a claim (not evidence): “Design A is better” or “Design A held 10 cubes”?
Answer: “Design A is better”. Claims state opinions; evidence gives measurements.
Flashcard 16: What is the best design when the goal is to get the largest result (for example, farthest distance)?
Answer: The design with the greatest measured value. Compare numbers and pick the highest one.
Flashcard 17: What does it mean to use evidence from data when choosing which design works better?
Answer: Use the numbers you measured to support your choice. Evidence means using actual measurements, not opinions.
Flashcard 18: Which design works better if the goal is fewest leaks and A leaked 1 time while B leaked 3 times?
Answer: Design A. 1 leak is fewer than 3 leaks.
Flashcard 19: Which design works better if the goal is most weight held and A held 5 blocks while B held 4 blocks?
Answer: Design A. 5 blocks is more than 4 blocks.
Flashcard 20: Which design works better if water held is A: 250 mL, B: 300 mL, and the goal is hold more?
Answer: Design B. 300 mL is more than 250 mL, so B holds more.
Flashcard 21: Which design works better if the goal is “go farther”: the one with the larger distance?
Answer: The design with the larger distance. Larger distance means it traveled farther, meeting the goal.
Flashcard 22: What is evidence in a design test: an opinion or the numbers you measure and record?
Answer: The numbers (measurements) you record. Evidence must be measurable and objective, not personal views.
Flashcard 23: Which design works better if weights held are A: 12 blocks, B: 9 blocks, and the goal is strongest?
Answer: Design A. 12 blocks is more than 9 blocks, so A is stronger.
Flashcard 24: Which design works better if times are A: 6 s, B: 4 s, and the goal is fastest?
Answer: Design B. 4 s is less than 6 s, so B was faster.
Flashcard 25: Which design works better if the goal is “hold more”: the one with the larger amount held?
Answer: The design with the larger amount held. More capacity means it holds more, achieving the goal.
Flashcard 26: Which conclusion is supported: A time 3 s, B time 6 s, goal fastest; “A works better” or “B works better”?
Answer: “A works better.”. 3 s is less than 6 s, so A was faster.
Flashcard 27: Which reason matches the data: A holds 10 blocks and B holds 6 blocks; why is A better?
Answer: It held more blocks in the test. The data shows A held 10 blocks vs B's 6 blocks.
Flashcard 28: Which statement is correct: a conclusion should use data or should ignore the data?
Answer: A conclusion should use data. Conclusions must be based on evidence, not opinions.
Flashcard 29: Which design works better for “fastest”: the one with the smaller time or larger time?
Answer: The design with the smaller time. Smaller time means it finished faster, achieving the goal.
Flashcard 30: Which design works better for “strongest”: the one that holds more weight before breaking?
Answer: The design that holds more weight. Strength is measured by how much weight it can support.
