ISBN 0-13-061146-8 Grading Policy: Tests – 60% Tests are given every two-three weeks, usually after each unit. Each test will consist of multiple choice questions and free-response questions. Labs and Quizzes – 30% Labs will be preferably open-ended with an objective and a list of equipment. Students will choose the procedure, collection of data and data evaluation. Each experiment will require a written report to be kept in an organized lab notebook [C6] Quizzes: Quizzes will be covering selected homework problems and/or recently covered material. Homework – 10% Homework is assigned every class period and will include textbook problems and/or AP free-response problems. Course Outline FALL SEMESTER I.
