Question

the passage below describes an experiment. read the passage and think about the variables that are described. aaliyahs brother thought that crushed ice would keep his soda cooler than whole ice cubes. to test this idea, aaliyah divided a large bottle of soda equally among six glasses. aaliyah added five whole ice cubes to each of the first three glasses while her brother crushed five ice cubes into small pieces before adding them to each of the other three glasses. ten minutes after all the ice had been added to the glasses, aaliyah used a thermometer to measure the temperature of the soda in each glass. which of the following was an independent variable in this experiment? the size of the ice pieces the temperature of the soda

Explanation:

In an experiment, the independent variable is what is changed or manipulated. Here, Aaliyah changes the size of ice pieces (whole vs crushed) to see its effect on soda temperature. The temperature of the soda is the dependent variable that is measured based on the change in the independent variable.

Answer:

the size of the ice pieces
