Design an experiment to test the effect of aeration on the growth of roots of bean seedlings. In your answer, be sure to: • state one hypothesis the experiment would test • describe how the control group will be treated differently from the experimental group • identify the dependent variable in the experiment • state one reason why many setups should be used in both the experimental and control groups • state one reason why several different kinds of seedlings were not tested in this experiment

Hypothesis can be: There is a significant difference between plants' height with aeration and with no aeration. Independent Variable: Aeration and no aeration Dependent varibale: growth of the plant measure through its height Many setups should be done to avoid inconsistencies and validate between results in the two treatment conditions.
