a magnet attracting some paper clips
Sally put three magnets of the same size in the freezer for 30 minutes. Then she held each magnet above a pile of metal paper clips and counted how many paper clips each picked up. She repeated this procedure after leaving the magnets at room temperature for 30 minutes and again after leaving the magnets in the hot sun for 30 minutes. She then calculated the average number of paper clips picked up by the magnets stored at each temperature.
