Encounter reduction-oxidation (redox) reactions, which involve the exchange of electrons between substances. Discover that this process explains geological events on the early Earth, including why iron in its metallic state is so rare in nature. Then explore associated phenomena, including the activity series of metals.

Turn from synthetic polymers to biopolymers - those that occur naturally. Focus on polysaccharides, nucleic acids, and proteins (including a special class of proteins, enzymes). Discover that living systems exercise a level of control over the synthesis of these polymers that no chemist could ever hope to achieve in the lab.

Examine solids that are held together by forces other than metallic bonds. For example, sodium chloride (table salt) exhibits a lattice structure joined by ionic bonds; molecular solids such as sugar have covalent bonds; and diamond and graphite are cases of covalent network solids, as are silicates.
