Question

Procedures: A list of materials and summary of steps has been provided for you. List and explain your controlled variables, independent variable, and dependent variable for this lab. Materials: 13 plastic cups (12 oz)permanent marker for labelingmeasuring sticktablespoon and teaspoonkitchen scale that measures in grams (optional)watersource of heat granulated sugarsugar cubes spoon for stirring 3–4 packages of powdered drink mix (6.6 ounces per package)Variables:Remember, 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.Controlled variables:Independent variable:Dependent variable:You can just list the variables and have a slight explanation :)) Thx for the help!!

Answer 1

• 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
