Exploring Chemical and Physical Properties of Matter

Miss Gardner introduces the concepts of physical and chemical properties, explaining their definitions and providing examples. Physical properties are characteristics observed without changing the material's identity, such as color, shape, and density. Chemical properties relate to a material's reactivity, like flammability and reactivity with acids. The video includes demonstrations of these properties using various objects and experiments, highlighting the importance of understanding these properties in chemistry.
