Add to ORKGIn lesson one, heat is used to distill ethanol. Iodine distilled from seaweed demonstrates the chemical phenomenon of sublimation. The principle of chromatography is explored by studying color pigments in water-base pens. Lesson two studies salt dissolution. Degrees of solubility are measured by dissolving quantities of boric acid at different temperatures. Recrystallization is achieved. In lesson three, bleach and pig's liver are combined to produce oxygen; carbon dioxide, ammonia, and hydrogen are produced and their properties are studied
