Ind+Var+Answer


 * Keeping in mind that the independent variable in an experiment is the single aspect of the experiment that is methodically chosen and changed to test for a relationship between it and the dependent variable, it should be easy to pick out the change that Anna is making in her experiment. Here is a possible answer. . . . . REMEMBER TAB!**

Anna's independent variable is the amount of Diazinon that she is using on the different tomato plants. I believe this is true because this is the only change that Anna is making each time she repeats her test on a new tomato plant and the independent variable is the one aspect of the experiment that is methodically changed to test for a relationship to the dependent variable.
