I am testing to see which brand of soap lasts longer. I am using 5 different brands of soap cut the exact size and placing in bowls of water the same temperature. I need help identifying the independent, dependent, and controlled variables. Thanks.

Hi,
The Science Buddies Project Guide has a good discussion on variables. Here is a link:

In your case the independent variable might be the type of soap. The dependent variable might be the length of time it lasts. The controlled variable might be water temperature.
I hope this helps.
Best regards,
