Test which one makes the indicator change the colour fastest.

Independent variables: type of acidic solution

Dependent variables: time for the indicator to change the colour

Controlled variable: amount of volume of solution.

  • independent variables: things you change during your experiment

  • dependent variables: things change when you change the independent variables

  • controlled variables: things that you keep the same during your experiment
