Today is my offical day working on the assignment. For the past couple of days I have been thinking about ways that I can approach the experiment which is 'do plants need soil to grow'. I have started the experiment by purchasing the seeds that I need for the task, I am attempting to grow red spring onions, as they can grow around this time of year. I will be planting the seeds into 6 plastic cups, 2 cups will have soil, 2 cups will have gravel and the other 2 cups will have cotton wool. These will be my independent variables. My controlled variables will be the amount of water,  the amount of sunlight and the size of seed
