Identify the independent and dependent variable of the experiment growing corn

Independent variable is the corn
Dependent is the amount of corn grown

The dependent variable is what is being measured in an experiment. The result of the dependent variable depends on the independent variable.

The independent variable is what is being changed in an experiment. The amount of corn planted, or the soil used, or the amount of sun. But, only one independent variable is changed.

So, I'm guessing how tall the corn grows is the dependent variable. And it depends on what you are changing for whatever to  be the independent variable
