On a cold day, a glass of water left outside undergoes changes in physical state. As temperatures drop, the water may turn into ice. A science teacher placed a beaker on a windowsill over four weeks, allowing students to measure volume changes. Factors such as temperature and sunlight may affect water volume. Additionally, analyzing the melting of an ice cube on a hot day illustrates physical state transitions. This activity engages students in hands-on learning about liquids and solids, enhancing their understanding of matter.
