Name the two differences between an independent variable and a dependent variable?
An independent variable is controlled by the experimenter and can be manipulated during the experiment.
A dependent variable's behavior is a result of the changes/manipulations made to the independent variable. The dependent variable cannot be controlled.

Identify the difference and the similarity between a controlled variable and an independent variable.
Difference
Controlled variables must remain constant throughout experiment. Independent variables can be changed/manipulated during an experiment.
Similarities
Both controlled variables and independent variables are chosen by the experimenter.
