Question

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

Answer 1

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.
