Design an experiment that tests how a change to a single factor (independent variable) will affect plant germination (dependent variable). It is important to control all other variables (control variable) in your experiment to determine whether the change you introduced had an affect on the germination of the seed. For example, if you want to study how light affects seed germination, you will want to set up three plants under different lighting conditions, and keep everything else-soil type, depth of planting, amount of water, fertilization, temperature-the same.
