The experiment and the control group are different in this experiment is that the experimental group is fertilized with Growmore. The reason why there is only one experimental variable so that i can test my hypotheses. If there were more than one variable we would not know which variable is causing the change. A control is necessary because we would not know the standard comparison on our experiment. A controlled experiment provide data to test our hypotheses and solve our problem.
I learned that my hypothesis was correct. What i found interesting about this lab is that the Cole Fertilizer Company asked me to test their product. What i found difficult to understand was the key words controlled experiment and control and also what were the difference
