In 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.
