Victoria is comparing laundry detergents. She set up an experiment to determine which detergent will be the most effective in removing stains from her clothes. Then she made a list of materials she will need to conduct the experiment. List of Materials • cloth • mustard • containers for washing • laundry detergent A • laundry detergent B • measuring cups Part A What should Victoria vary in her experiment to test the effectiveness of the detergents? Explain why this is important. Part B What variable should Victoria keep constant in her experiment? Explain why this is important
The variable, which would be only thing that could really be changed in the experiment, would be the cloth. Change it to a different material and you'll get a different conclusion. The detergents would be considered the constants in a scientific method process. The constant, like I just said, are the detergents. Those are the two things that should not be changed, since you're trying to determine which is the more effective on a type of cloth.
