Understanding Mixtures and Solutions

Professor Bill Tyson introduces the concept of dissolution in homogeneous mixtures, using salt and water as an example. He explains the roles of solute and solvent, and discusses mixtures in different states, such as bronze and air. The video concludes with a call to share the importance of teaching science to children.
