Shakita wants to know if the pH of an open can of soda changes over time. To test this, she designs an experiment that will involve the following steps.
Open a can of soda and measure the pH.
Allow the open soda can to rest undisturbed on a level countertop at room temperature.
Measure the pH of the open soda can every day at the same time for ten consecutive days.
What is the dependent variable in Shakita's experiment?
A. the pH of the soda
B. the type of soda
C. the temperature of the room
D. the number of days

Best ResponseYou've already chosen the best response.0The independent variable is independent and is not depended on another variable. The dependent variable is dependent on the independent variable and changes and that is the one that you measure in an experimental setting
