Concepts: â  Phase Change â  Atomic theory This lesson provides a concreteexperience of: â  Ice melting. â  Water freezing. â  Evidence that liquid water and solid icearedifferent phases of the same substance. PRE KâGRADE 2 CONCEPTS â  When solid ice is warmed to its meltingpoint, it melts into water. â  When liquid water is cooled below a tem-perature known as the freezing point ofwater the liquid water becomes solid ice. â  As water changes into ice, or ice changesinto water, its properties also change. Forexample, as water freezes in an ice cubetray, it forms layers at the outside, like ashell, and the inside freezes last. Themelting and freezing occurs at the surfacelayer.
