I did mind on How water affects the growth of beans(hypothesis). I placed 5 single beans in cans with dirt in them. The water was measured and the same amount was given. (controled method). The difference was the days their were watered. One was watered daily, it drown in water, second was watered every other day, it also drown. third was watered every third day. the fourth one was watered every 4th day. and the fifth every fifth day. All were placed by a window where they were exposed to the same light. You can actually see a difference in growth between the last three beans. Their size varies extremely. Your conclusion would be that water how much water is given really affects their growth
