Answer (1)
HypothesisIf different cleaning methods (oil, water, and ice) are used to remove bubble gum stains from the wall, then one method will be more effective than the others in removing the stains.Independent VariableCleaning Method - The type of cleaning method used (oil, water, or ice).Dependent VariableEffectiveness of Stain Removal - This could be measured by the degree to which the bubble gum stain is removed (e.g., percentage of stain removed, visual assessment of cleanliness).Controlled VariablesType of Stain - The same bubble gum stain should be used for all tests.Surface Material - The wall surface should remain constant (same paint type and texture).Amount of Cleaning Agent - The same quantity of oil, water, or ice should be used for each method.Duration of Cleaning - The time spent applying each cleaning method should be identical.Environmental Conditions - Factors like temperature and humidity should remain consistent during the experiment.
