Answer
• Controlled variables: Cup size, water and heat sources
,• Independent variable: Temperature, agitation, particle size, dilution
• Dependent variable: Taste of a drink
Procedure
As detailed in the lab introduction/ background:
• Controlled variables are factors that remain the same throughout the experiment.
,• An independent (test) variable changes so that the experimenter can see the effect on other variables.
,• The dependent (outcome) variable will change in response to the test variable.
By looking at the purpose of the experiment and the materials/ingredients we can classify the variables as follows:
• Controlled variables: Cup size, water and heat sources
,• Independent variable: Temperature, agitation, particle size, dilution
,• Dependent variable: Taste of a drink
