You might start by taking a look at: https://www.sciencebuddies.org/science- ... bles.shtml

Your experiment is to take samples of each fruit and measure the pH. What choice are you making? The result is the pH. If the independent variable is your choice and the dependent variable is the result, can you see which variables are which?
