Application of the Scientific Method - Assignment Example Which is the best detergent to use when cleaning dirty clothes? Many detergents exist all for the purpose of cleaning. Some have the best advertisements and are thus popular; others have the chemicals that clean clothes without much effort, while others have negative effects on the user’s skin when frequently used. Some detergents are also used not only because of the effectiveness in cleaning but because they have fair prices and are cheaply available to many. Liquid detergent cleans clothes faster and more thorough than powder detergent. To prove this hypothesis, both types of detergents have to be used on the same type of cloth containing an equal amount of dirt or stains and under the same environmental conditions in terms of temperature of water used and also the type of the water itself, whether soft or hard. Such conditions ensure that the detergents are tested on fairgrounds and that the results obtained can be reliable when it comes to making conclusions on the best detergent. Testing this hypothesis is important in making comprehensive conclusions. To test the hypothesis, a piece of clothing of a reasonable size, say one square meter, could be dirtied with mud, oil, food spills and colored fluids. These should be evenly distributed on the piece of clothing to ensure that every part gets an equal share of dirt. The clothing could then be cut into two pieces, each of equal size. Water from the same source should be put in two different buckets. The powder detergent could be dissolved in one bucket and the liquid detergent in the other. The two dirty pieces of cloth should be soaked into the two buckets for the same amount of time. The amount of dirt removed from the pieces of cloth by soaking should be compared. The pieces of cloth could then be hand washed in the detergent and the amount of time and effort taken to clean each noted.
