Experimental Scenarios Study Guide
Science
Directions: Read the given scenarios below. Identify each required component for
each scenario.
Scenario 1:
A student is studying how far room temperature water would squirt out of a plastic
milk carton when 4 mm holes are punched at different heights from the bottom of
the container
Describe which are the independent and dependent variables as well as indicates
the constants involved within the experiment and why those are the constants.
Independent Variable:
Dependent Variable:
Constants:

Independent variable: height of holes

Dependent variable: distance of squirting water

Constant: size of holes punched into the milk carton

Explanation:

The independent variable is one whose value is often manipulated during the course of experiments and the effects produced by the manipulation is measured on the dependent variable.

The dependent variable is the actual variable that is being measured in the course of experiments. The value of the dependent variable is affected by changing the values of the independent variable.

Constants are variables whose values remain unchanged throughout the course of experiments.

Hence, in the illustration:

Independent variable: the height of holes on the milk carton

Dependent variable: distance of squirting water

Constant: the size of holes punched into the milk carton
