The passage below describes an experiment.

glasses of soda with ice

Haley's 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.
