In the last part of this experiment, the temperature of tap water was recorded for fifteen minutes as the tap water was heated in a beaker. Identify the dependent and independent variable.
(THE TEACHER Just said THE DEPENDENT AND INDEPENDENT VARIABLE but idk if he/she wants multiple VARIABLESSS) Justify the answer: (But How do you justify the answer, I'm confused.) ???
Independent Variable (variables that do not change throughout the experiment): timer, beaker, thermometer, bunsen burner & tubing, wire gauze, striker, red hot grippers, ring stand, graduated cylinder, glassware brush
Dependent variable: I'm not sure if some of the items above are dependent variable.
