In this activity, a possible problem related to global warming is clarified by the principle of states of water. The activity consists of an experiment that includes three scientific principles: Archimedes' Principle, the Law of Conservation of Matter, and the fluidity of liquids. The experiment helps students raise questions and open new horizons of curiosity in their minds. It forms bridges between the mind and senses in the physical world and encourages integrated thinking in science. The experiment could easily apply to any school level, including elementary or middle school, and in any context. (Contains 3 figures.)
