These concepts build upon the foundations studied in Chemistry I. It will also move into the world of organic chemistry, a branch of chemistry that has over 3 million known compounds, many of which are central to life. These advanced concepts allow for a greater understanding into the workings and characteristics of the materials we use every day and how life itself operates. Chemistry is both descriptive and mathematical. We will explore both aspects in depth and you will need to be proficient in both to be successful in this course. Class expectations: Consistent attendance is important. Make every effort to be in class each day. If you are absent, it is your responsibility to obtain any make-up work and notes. You may contact me using the email address above. Absences due to school business; field trips, athletic events, etc., do not excuse you from the work for that day. Plan ahead. Come to class prepared each day with paper, pen or pencil, calculator, book, and completed homework. Be on time. Class will begin promptly. Tardies to class will be handled in accordance with school policy. (p. 19 of Student Planner) Portable electronic devices may not be used at any time unless permission is given. Phones and tablets may not be used on a test as a calculator. The best action is There is no eating in class. You may drink water only in class, but never when we are in the lab. Treat everyone with the same level of respect that you would like to be treated. Raise your hand to be recognized before asking or answering a question. Ask for help sooner rather than later. Assessment and grading: I use a point system to determine grades. Each assignment is given a point value based on its importance to the unit. For example, unit tests will carry a 100 or more point value, while a unit quiz may carry a 20 or 30 point value. At the end of each grading period the total points you have earned will be compared to the total points possible and a percentage grade will be assigned. Assessment and grading continued: Work that is turned in late will receive a 10% reduction for each day it is late up to 5 days, at which time it will be given a zero. Daily homework grades are not accepted late. The final course grade will be computed as follows: (1st nine weeks grade x .45) + (2nd nine weeks grade x .45) + (final exam grade x .10) Course Outline: Unit 1: Chemistry Foundations: Review Concepts from Chem-I.
