Savannah 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. She didn't put any ice in the last glass. Ten minutes after all the ice had been added to the glasses, Savannah used a thermometer to measure the temperature of the soda in each glass.
