This student guide is divided into two sections, "Chemistry of Living Matter" and "Energy Capture and Growth," constituting parts three and four of the third year of the Portland Project, a three-year high school integrated science curriculum. The underlying intention of the third year is to study energy and its importance to life. Energy-related concepts considered in year one and two, and the concepts related to atomic structure and particle phenomena considered earlier in the third year are further built upon in this volume by these chapters: monomers and how they are built; some chemistry of simple carbon compounds; polymers or stringing monomers together; polymers in 3D or the shape of things to come; where the action is-the active site; polymers to polymers; genes, proteins and mutations; energy capture; energy consumption and metabolism; and metabolism and genes. Reading assignments and experiments for the third year are contained in the student guide. Half of each page is left blank for the purpose of taking notes.
