Four bean seedlings were studied and their rate of plant growth over time was measured. Each of the seedlings were placed in a similar flask
and the same amount of water and soil was added. Every week 0.2 grams of plant fertilizer was also added to the flasks. Based on the figure
above, determine the independent variable in this experiment. What is independent variable
