            Invetigation of which the outcome results will determine what temperature the soap powder, Wizzo, will best perform at.
             Introduction.
             I am going to conduct an experiment in the controlled environment of a laboratory. The experiment will consist of placing a stained piece of fabric into water with a fixed concentration of a biological washing powder (Wizzo) in it. I will try this experiment several times trying different temperatured water and leaving the it for a fixed period of time to find the best possible temperature that the Wizzo works at.
             .
             Plan: Enzymes .
             Biological washing powder has bin around for many years to clean clothes more efficiently. We know washing powder helps in the cleaning process because it contains enzymes. Previous experiments have found that the enzymes break down larger dirt molecules into smaller dirt molecules. Therefore speeding up the process of cleaning clothes (catalyse) as the water can wash them away quicker. .
             Another example of enzymes is the digestive system in the human body. Enzymes called protease are produced by the stomach, the pancreas and the small intestine. These enzymes catalyse the break down of fatty acids into amino acids. These enzymes work best at 37 degrees celsius whcih is body temperature. .
             Formalahdehyde is the enzyme which is commonly found in biological washing powder. The enzymes break down the dirt molecules in clothes into smaller dirt molecules thus making it easier for the water to clean away. I will determine at what temperature the enzymes in the Wizzo best perform at, which is the point of my experiment.
             Hypothesis.
             I predict that 40 degress celcious will be the most effective at cleaning the stained fabric as my research into enymes showed that other enzymes (protease in the human body) worked best around that temperature. Although comparing enzymes in the human body to enzymes of a biological washing powder seems outlandish but the experiment will prove or disprove my hypothesis to see if these enzymes have simularities.
