First of all, make sure that the plants are all the same and are all fresh and not withered. Take the first plant and put it in the area where you are doing your experiment. Water it and let it stay. Next, take the 3 detergents and mix half a cup of detergent with half a cup of water and pour the mixtures in each of the remaining 3 plants. Do this for the next 7 days and record your results below after the 7th day.
