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.

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 de

I will be repeating the experiment three times for each individual temperature to obtain more reliable results. I will then take the results and form a table. The table will have the average number for each temperature. This will show I have followed and carried out my experiment correctly as there should be a desticnt pattern. I will then produce a graph from these results and a pie chart from the averages. (See Appendix C and D).
