Question

in mrs. walkers science class, students worked in groups to test how sound travels through solids, liquids, and gases. she provided tools for their work and allowed them to choose from a variety of investigations, such as testing a simple phone made of cups and string. when students completed their activities, she asked them to compare their methods and results with those of other groups in the class. think about the benefits of comparing methods and results among class groups and within the science community. which statements are true about comparing methods and results? (choose 3) a sharing methods and results with other groups can help improve investigations. b groups in classroom settings should compare their work because they are learning, but scientists in the real world do not do this. c comparing results with groups who used the same methods can help find errors. d groups who used the same methods will always have the same results. e groups who use different methods will never have the same results. f when groups compare methods and results, they are doing what scientists in the real world do.

Explanation:

Sharing methods and results helps improve investigations (A). Comparing results with other groups can find errors (C). Groups in a classroom setting should compare work as it's part of the learning - process like in real - world science (B). Different methods don't always yield different results and same methods don't always yield same results due to various factors.

Answer:

A. Sharing methods and results with other groups can help improve investigations.
B. Groups in classroom settings should compare their work because they are learning, but scientists in the real world do not do this.
C. Comparing results with groups who used the same methods can help find errors.
