Two students want to figure out if water temperature affects how fast sugar dissolves. Student A puts one spoonful into small cup of cold water and student B puts one spoonful into a pot of hot water and stirs it. Their results show that the sugar dissolved faster in the hot water. Can they safely say that the temperature was the reason? How could they improve their experiment?
