Re: Ph indicators
Hi Morgan,
An independent variable is something within your experiment that you change to observe or measure a response in a dependent variable. What are you changing in your experiment that will make the different pH indicators? That is your independent variable. What are you measuring to test your pH indicators? That is your dependent variable.
You may want to review the information on variables at the following link.

Please post again if you need more help with your independent and dependent variables.
I hope this helps. Please post again if you have more questions.
