Planning Aim To fine whether different type of sugar solution effect the rate of fermentation. How does it effect the rate and which type of concentration works best. Factors affecting the rate of fermentation * Temperature * Type of sugar * Concentration of sugar * Amount of sugar The factor I have chosen is to vary is the concentration of sugar. The concentration will be 200%, 150%, 100% and 50%. Safety precaution * Hot bath is dangerous and you might boil you hand therefore …

…was nearly all right except on which was that the amount of carbon dioxide given off will increase as the concentration of sugar increase was wrong because that it is exactly the opposite. Except that the other prediction is the same as the result. 100% concerntration with 3 g per 100 mil.
