... An Investigation To Show The Varying Amounts Of Microbial Decay Caused By The Amounts Of Water Added. Aim Our aim is to find the best type of soil for microbial decay. Apparatus * 15 pieces of raw cabbage 4cm2 (three in each pot), * Five plastic pots, * Five pots of different types of Soil/Compost, * Five labels, * Weighing scale, * Rulers * We will put all pots in the same place making the temperature the same for each pot (room temperature). This will make the test fair. Variable We have decided that we will have one variable this will be the variation in the amount of water we give the plant at the start of the test. We will have the following: * 1 tub of peat soil, * 1 tub of sandy soil, * 1 tub of sterilised soil, * 1 tub of soil from the environmental area, * 1 tub with no soil. It is important to keep all other possible variables constant
