Mr. Kline's earth science class set up an experiment to compare the heating and cooling rates of land and water. They filled cups with sand and water and then recorded the temperature change while (a) a light was shining directly on the cups and (b) the light was turned off. The data one group collected is presented in the data table. Based on this data, we would expect to have the LEAST changes in temperatures during a 24-hour period.
