In the demonstrative laboratory on homogeneous and heterogeneous mixtures, students engaged in hands-on observation of different types of mixtures. They explored the interaction of substances to identify those forming homogeneous mixtures, where components are evenly distributed, and heterogeneous mixtures, characterized by a non-uniform distribution. Furthermore, students witnessed the phenomenon of diffusion by observing the dispersion of colored dye particles in a liquid medium such as oil, allowing them to grasp how substances can exchange and distribute in varying conditions. This practical approach in the laboratory contributed to strengthening their understanding of fundamental chemistry concepts and the properties of mixtures.
