Science Buddies: "Ask an Expert"

My daughter is having a hard time figuring out the independent variable dependent variable and the constant and control.
Our project was what liquid will melt an ice cube faster water, soda or Gatorade.
She had put independent var the liquids
Dependent the ice cube melting
Constant was the amount of liquid and amount of ice
Controlled was the temp, ice, liquid
The last two I wasn’t sure of
