The Study of Alternative Soils
We investigated the possibility of growing bean plants media other than soil. We accomplished this by choosing three alternative media, sand, coffee grounds, and peat moss, and growing 50 bean plants in each media alongside 50 bean plants growing in soil. We measured the height of each plant each week for six weeks and compared the mean value of the height of the plants growing in soil to the mean value of the other plants. Using the T-test, we were able to to determine the time we measured, sand was the best alternative to soil, then coffee, then peat moss. Although evidence indicates that if the experiment was continued, coffee would actually become the best alternative.
