What is the CONTROL, Independent & dependant variable of a science project?

Question

i have a science project on which evaporates faster: Distilled water, sugar water, or salt water.

For my presentation i need to know what the CONTROL, Independent, and dependent variables are. thanks for your help ;]

Answer 1

The control is your Distilled Water (because it contains just water)

Dependent variables are those that are observed to change in response to the independent variables (time taken to evaporate).

The independent variables are those that are deliberately manipulated to invoke a change in the dependent variables. (Type of ingredient used)

Answer 2

Control: Distilled water

The independent variables don't rely on anything to perform, however dependent variables do. I would say that sugar and salt water would be independent variables.
