Honors Chemistry Course Description and Philosophy Chemistry is the study of matter and the changes it undergoes. This is a comprehensive and intensive course in experimental and conceptual chemistry. The work includes history and methods of science and ranges over the nature of atoms, molecules and reactions. Among the major topics are structure, nuclear chemistry, quantum chemistry, bonding, formula and equation writing, stoichiometry, changes of state, thermochemistry, solutions, kinetics, equilibrium, and electrochemistry. Understanding the periodic table, developing laboratory techniques, interpreting data, and writing up experiments are stressed. The extensive laboratory work ranges from investigating the fundamental laws of chemical change to the analytical chemistry of acid-base titration and determination of reaction rates. It is expected that students who enroll in this course will be able readers and proficient in basic algebra. Instructional strategies for this course include lecture, laboratory activities, demonstrations, group discussions and student board work. Student performance will be evaluated using teacher-generated tests and quizzes, homework assignments, laboratory write-ups, and class participation, as well as two half-year examinations that will represent 20% of the students’ final grade for the course.
