Question

the passage below describes an experiment. haleys brother thought that crushed ice would keep his soda cooler than whole ice cubes. to test this idea, haley divided a large bottle of soda equally among six glasses. haley added five whole ice cubes to each of the first three glasses; her brother crushed five ice cubes and added them to the other three glasses. ten minutes after all the ice had been added to the glasses, haley used a thermometer to measure the temperature of the soda in each glass. identify the independent variable and dependent variable in this experiment. the size of the ice the temperature of the soda

Explanation:

• Independent variable: The factor changed (ice size: whole vs crushed) to test its effect.
• Dependent variable: The factor measured (soda temperature) that depends on the independent variable.

Answer:

Independent variable: the size of the ice
Dependent variable: the temperature of the soda
