Comparing Design Strengths - 1st Grade Science
Card 1 of 15
Which option best describes a fair comparison: testing both designs in the same place and time, or in different places?
Which option best describes a fair comparison: testing both designs in the same place and time, or in different places?
Tap to reveal answer
Testing both designs in the same place and time. Same conditions ensure differences come from the designs, not the environment.

What should stay the same in a fair test when comparing two designs?
What should stay the same in a fair test when comparing two designs?
Tap to reveal answer
Only one thing changes; the other conditions stay the same. Fair tests require controlling variables except the one being tested.

What does it mean if a design has the same result in repeated tests?
What does it mean if a design has the same result in repeated tests?
Tap to reveal answer
The result is consistent. Consistent results show the design performs predictably.

Which design has the higher success rate: Design A $ rac{7}{10}$ or Design B $ rac{6}{10}$?
Which design has the higher success rate: Design A $ rac{7}{10}$ or Design B $ rac{6}{10}$?
Tap to reveal answer
Design A. $\frac{7}{10} > \frac{6}{10}$, so A succeeds more frequently.
