Identify Variables in Experimen t

Suzie notices that her aprons are always appearing to be dirty even after they have been washed. She is wondering if she uses this new stain remover advertised on TV then her stains will wash away and her aprons will not appear dirty when they are clean. She takes 3 aprons that she wears regularly making sure that each apron has the same type of stains on them. She washes apron 1 with just Gain on the normal washing cycle and dries as normal in the drier. Apron 2 is sprayed with her regular stain removed. Each stain is sprayed with the stain remover 2 times just before it gets put into the washer to wash. Apron 3 is sprayed with the new stained remover advertised on TV - Grandma's Stain Remover. The stains on this apron are sprayed 2 times just before it is put into the washer to wash. Each apron is washed and dried alone. Apron 1 shows no change in the stains. Apron 2 shows the stains being lighter but still present. Apron 3 shows the stains barely there.

What is the independent variable in this experiment?

• Gain

• Regular stain remover

• The stains

• Grandma's Stain Remover
