Maria designed an experiment to determine whether water or land gets hotter in the sun. She set up a pan of water and a pan of soil, each with a thermometer in it. She placed the pans in the sun for ten minutes and measured the temperature in each pan once every minute. What was the independent variable in the experiment?
