This experiment was conducted to find out how the amount of fertilizer used will affect the growth of plants. The experiment was done using levels of fertilizer lower and higher than the recommendation by the manufacturer.
Procedure preview:
1.    For this experiment, the independent variable is the concentration of fertilizer in the water. The dependent variable is the growth of the radish plant. This is determined by measuring the average height of the 3 plants in each group and calculating the average height. The constants (control variables) are the amount of water  and the type of plant used. 2.    The 15 pots are filled with the same amount of soil. One radish seed is placed in each pot. (More than one radish seed can be used in each pot in case some of the seeds do not germinate. .....
