Controlled Expirment

Although we were supposed to plant lettuce seeds, instead by mistake we added bean seeds. The first week after we planted the seeds, there had been no change. Every day we would look at our control cup and variable cup and neither of them had any sprouting. Each day we added about 10 mL more water and then on the following Monday we added about 30 mL more water. Then when we went back to check our cups on Wednesday our beans had sprouted and grown. The growth rate of the "variable" cup, which had the remediation done to it, was a bit larger than the growth rate of the control cup. We know this because the plant in the variable cup was larger, meaning it had grown quicker. Also the variable cup had a darker green color than the control cup plant. They both had the same number of leaves: 4. The survival rate was higher for the variable cup because by Friday the crop in the control cup had began dying.
