The aim of the experiment was to find if Fertliser effected the growth of the Tomato plants. My prediction was that the fertilised plant will grow more then the plants that were water. The fertilied plants will grow more because the fertiliser has element that the water cant give the plants that make it grow. The elements that fertiliser has is nitrogen, phosphorus and potassium. This is why the fertilised plants grew so much.The experminent was used to investigate the difference between the growth of Tomato plants with fertiliser and with water. It aimed to test to see if one liquid made the Tomato plants grow more than the other liquid. The growth of the pants were recorded.Independent Variable: Half of the plants are fed with fertiliser
