Question

1. Experimental results are compared against

the results of controls. How can controls
improve an experiment? sc.6.N.1.3
Aby ensuring that the experiment tests
only one variable
B by allowing for the experiment to test as
many variables as possible
D
by making sure everything in the
experiment remains constant
by guaranteeing that the experimental
outcome verifies the hypothesis

Answer 1

How do controls improve an experiment?

Not only do controls establish a baseline that the results of an experiment can be compared to, they also allow researchers to correct for possible errors. If something goes wrong in the experiment, a scientist can check on the controls of the experiment to see if the error had to do with the controls.

In your case your anwser: B. by allowing for the experiment to test as many variables as possible
