In this experiment the beginning plants would all need to be the same size and the water would be the variable (put different amounts of water into each plant) the size of the plant would be a result.

Are controls always necessary in an experiment?

Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results

Why is an idependent variable needed?

An independent variable is a variable that you can control, you can choose and manipulate this variable. An example is an experiment looking at the growth of trees in the Dark, in a dimly lit room and in the direct sun. So you are going to put one plant in the sun, one in the dark and another in a dimly lit room. The independent variable is the location of the experiment, because this is what is being changed. The dependent variable may be the type of the plants and the height of the plants to begin with, The results on which is determined by the independent variable (ie amount of sunlight on the plants) So basically, without the independent variable you cannot really measure the full extent of the results. Uhm, I hope that makes sense, haha.
