triple beam balance
Eleanor studies for a quiz with music playing or in silence to see which leads to a higher test score.
What is the independent variable in this experiment?
music playing or silence (or whether or not there is music playing or not) (or something similar)
Which of the following best describes a controlled variable?
a) It changes when the independent variable changes. c) It stays the same throughout the experiment.
b) It’s the outcome the researcher measures. d) It’s what the researcher predicts will happen.
c) It stays the same throughout the experiment.
After thinking of some interesting questions, the next step in the scientific method would be to propose a _____________, or a testable prediction, that would answer one of those questions.
