Explanation:

A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.
