Heating Matter: From Ice to Steam Explained

Next Generation Science

This educational video provides a clear, visual demonstration of the three states of matter—solid, liquid, and gas—using water as the primary example. Through a live laboratory demonstration, a presenter heats ice in a beaker to show the transformation from solid ice to liquid water, and finally to water vapor. The video explicitly connects the addition of heat energy to these phase changes, known as melting and evaporating. Key themes explored include the physical properties of matter, such as how solids maintain their shape while liquids take the shape of their container but maintain their volume. Crucially, the video introduces the particle theory of matter using animated diagrams overlaid on the footage. These animations visualize how particles are tightly packed in solids, slide past one another in liquids, and move freely in gases. This resource is highly valuable for elementary science classrooms as it bridges the gap between observable phenomena (ice melting) and abstract concepts (molecular arrangement). Teachers can use this video to introduce the water cycle, thermodynamics, or the basic definitions of matter. It provides a "virtual lab" experience that allows students to see the process of boiling and evaporation safely and clearly, serving as a perfect anchor for lessons on physical changes.
