Techniques for Separating Mixtures

Teacher Sheila introduces techniques for separating mixtures, including hand picking, decantation, sieving, filtration, magnetism, evaporation, distillation, and chromatography. The video explains the differences between suspensions and colloids and provides examples of each. It concludes with a quiz to test understanding of the material.
