PREREQUISITE: Requires CHM151 and CHM151LL. It is strongly recommended that these prerequisites have been completed within the past 24 months.

OFFICIAL WITHDRAWAL DEADLINE is 7 Calendar days from class start date for 100% refund.

SYLLABUS: This syllabus is viewed by the administration as a binding contract between you and your instructor. Information included in this syllabus is subject to change. If changes do occur the class will be notified by the instructor of any changes in course requirements and policies by your college email address. It is the students responsibility to be fully aware of the contents of this syllabus. Students are also responsible for the college policies included in the college catalog and student handbook. (http://www.mc.maricopa.edu/students/07_08_catalog/S7_mcccd_policies.pdf).

DISABILITY ACCOMODATION: IF YOU HAVE OR THINK YOU HAVE A DISABILITY, INCLUDING A LEARNING DISABILITY, PLEASE MAKE AN APPOINTMENT WITH AN ADVISOR AT DISABILITY RESOURCES AS SOON AS POSSIBLE. THEY CAN ASSIST YOU WITH APPROPRIATE ACCOMMODATIONS FOR YOU IN YOUR CLASSES. Contact Disability Resource Services by voice at (480) 461-7447 or (480) 969-5587 tdd or visit http://www.mc.maricopa.edu/students/disability/. Be assured that I am willing to make any reasonable accommodations for limitations due to any professionally diagnosed disability, including diagnosed learning disabilities. However, no special accommodations can be provided until a completed Instructor Notification Form is received from Disability Resource Services. Please note that it is the responsibility of the student to make all necessary arrangements in order for accommodations to be provided.

CLASSROOM HONESTY AND INTEGRITY: Nothing says more about a person than his or her honesty and integrity. Since students compete with one another for grades and positions in degree and training programs, cheating is considered a serious offense. Students should consult with the student handbook or the catalog to review the policies and consequences of cheating. Rather than resort to such tactics, a student should contact the instructor and see if some extra help may resolve any problems in the course.

VIOLENCE PREVENTION: The Maricopa Community Colleges are committed to providing a safe environment for its students, visitors and faculty. Acts of violence, threats of violence, harassment, intimidation and other disruptive behavior will not be tolerated. Please report any occurrence of such conduct. All reports will be taken in confidence, seriously and will be dealt with appropriately.

THE DISRUPTIVE STUDENT: Even noisy and obnoxious behavior will not be tolerated. If you feel that your learning is compromised by these disruptive students, you need to inform your instructor of the situation. Those disruptive students will first be warned, if necessary removed from the classroom (by security), & ultimately dismissed from the class with a Y. PHONE QUIZZES: Ringing or noisy cell phones and beeping pagers often disrupt class. If the class is disrupted with one of these devices, a phone quiz will automatically be given at that time and will cover material that should have been read before class. Text messaging during class will be treated in the same manner. Continued abuse will obviously result in more and harder quizzes.

FOOD AND BEVERAGE POLICIES: No food or drinks are allowed in the classrooms. Abuse of this rule could initiate food/Drink Quizzes

ATTENDANCE: The Maricopa Community College District requires class attendance. More than three unexcused absences may result in a student being dropped from the course. Although attendance is required, the instructor is aware that unavoidable situations, such as illness, transportation problems, family emergencies, etc., may arise that requires a student to miss a class. In the event of such an emergency, the student should call one of the phone numbers listed below the same day of the scheduled class, and the absence will not be counted against the student. If an quiz is missed due to an unexcused absence, a make-up quiz will only be given at the discretion of the instructor. Make-up quizzes will be available at the testing center for only one week following the administration of the original quiz. These quizzes will be more difficult than those given in lecture.

CALCULATORS : Students will find calculators to be indispensable tools in this course. A good cheap scientific calculator, capable of all basic math, exponential functions and logarithms should be available for homework and exams. Expensive graphing calculators are not recommended. They have a tendency to disappear. Programmable calculators are not allowed for the lecture test.

GRADING: The grade for this class is based on the following:

Quizzes — 200 points a) There will be at least 10 quizzes each worth 20 points. Quiz format will vary, including problems, multiple choice, sketching, etc. b) All quizzes are closed book and may include any material covered in class BUT primarily that material covered since the previous quiz. c) Quizzes will usually be given on Thursday d) The quiz will typically be given out at the beginning of class. If you come late, you are given only the amount of time remaining from when the quiz was first passed out; therefore, I encourage you not to be late! If you come and take the quiz and leave early, your quiz will not count for credit. e) If a quiz is missed, the grade will be a zero. There are no make-up quizzes unless the instructor was given prior notification (for school functions only).

Weekly problem Assignment—200 points a) There will be at least 10 problem sets each worth 20 points. These sets will typically contain one or two problems. b) Each set will have space for four names (group work). c) You can count on some of these same problems appearing on the quizzes. At the least you can expect the same problem styles. d) Problem sets turned-in during or after class has started are considered late and points will be deducted. The amount of points deducted will be determined by the instructor. e) Late assignments will not be accepted once graded materials are returned.

Reading Assignments — 100 points a) I will hand out reading material throughout the semester that will compliment the lecture. Most of the reading material will be short journal articles, excerpts from books, case histories, etc. You will be required to read and summarize or answer questions from each article. Each assignment is worth 20 points. b) In each summary, you will describe the main points of the article, answer questions, and comment on what you learned from the article. The summary should be less than one page. These readings may also be included on the weekly quiz. c) All reading summaries are due at the beginning of class. You need to be present in class for discussion in order to receive full credit. Assignments turned-in during or after class are considered late and depending on the assignment, points will be deducted or the assignment may not be accepted. The amount of points deducted will be determined by the instructor. d) If you are not present in class when the articles are distributed, then it is your responsibility to get a copy of the article from your instructor prior to the due date. Also, if you know you are going to miss class, you can always turn your summary in early. e) Late assignments will not be accepted once graded materials are returned f) There are no make-up assignments.

Graded Computer Exercises —100 points

a) You will be required to do a total of five graded computer exercises on topics assigned by the instructor after we cover the material in class. Each exercise will be worth 20 points. b) The graded computer exercises will be done as group work. Remember a maximum of four students per group.. c) Graded computer exercises turned-in during or after class has started are considered late and points will be deducted. The amount of points deducted will be determined by the instructor. d) Late assignments will not be accepted once graded materials are returned. Poster—100 points

Mid Term Exam -100 points

Final Exam — 200 points a. The final exam is mandatory, comprehensive, and must be taken at the scheduled time. b. The previous quizzes and concept maps are your study guides for the final, so please go over them after each is handed back and correct any mistakes (do not wait until the last day of class.). c. The final grades are based out of 1000 points and will be assigned using the following grade scale:

A = 90% or above, B = 89.9-80%, C = 79.9-70%, D = 69.9-60%

d. I reserve the right to make any necessary modifications.

TESTING: The graded problem sets will be mostly problems while the test will be problems and some short discussion-type questions. On each test you will be responsible for the material covered up to that point in class. You should keep all your graded material for rectification of any grading disputes.

MAKE-UP TEST: A make-up test will be made available in the testing center for only one week following the mid-term test. This test will be significantly harder than the one given in lecture. The make-up test will be graded at my leisure. To remain enrolled in this class you must complete the mid-term test and the final.

GRADING : 12 Problem sets @ 20 pts each (drop 2) [Group Activity] 200 pts 1 Mid-term test @ 100 pts 100 pts 12 Quizzes @ 20 pt each (drop 2) 200 pts 5 Exercises @ 20 pts each [Group Activity] 100 pts Poster presentation [Group Activity] 100 pts 5 Reading assignments @ 20 pts each 100 pts 1 Final 200 pts 1000 pts.

NOTE TAKING: You may tape record lectures for study purposes only. However, you do not have my permission to sell the recorded lectures for monetary gain.

HOMEWORK: The odd numbered problems at the end of each chapter should be worked, but they are for the student's benefit and will not be collected. The answers are given at the end of the book. There also is a solutions manual on reserve in the Library.

EXTRA CREDIT: Students may acquire up to a maximum of 20 extra credit points for either of the following options. (1) Students may obtain extra credit points by participating in the departmental outreach program. In this program the Physical Science Department provides science activities for K through 12 students in the area. There should be one or two of these projects during the Fall semester. You may acquire 2 points per hour. Typically these sessions will last approximately four to six hours and may be on or off campus. More information will be available at a later date.

OR ((2) Students may volunteer their time at the Arizona Mineral and Mining Museum in downtown Phoenix (ph. 602-255-3791). This time must be pre-approved by the instructor and the Museum Staff. Students will receive 2 points per volunteered hour.

OR (3) you may donate printer cartridges or cell phones in behalf of the Phoenix zoo. You can pick up mailer at the zoo entrance for the acceptable cartridges (Epsom and Cannon are excluded) which you then bring along with the printer cartridges to my office to obtain your credit. The cell phones must be turned in at the zoo entrance where you can get a receipt. Each acceptable cartridge or cell phone is worth 2 pts per item.

Anyone interested in participating in a 1 credit Service Learning Class (especially education majors), please see me for details.

All extra credit is due by December 1, 2008. SERVICE LEARNING: Those students that are majoring in education may wish to participate in the departmental outreach program for credit. This is extremely beneficial towards developing a well-rounded background in the area of education. Demonstration of these types of activities with children helps towards admission into the education programs at major universities. One hour of credit may be obtained for participation in four of the departmental activities. You cannot get extra credit for the class and service learning credit at the same time. See me after class.

STUDY HINTS: There is no substitute for lecture attendance and good note taking. The student will find that regular review of class notes, along with text study, will provide good all-around preparation for tests. It is important to keep current and study on a regular basis. In addition, for each chapter assigned, the student should thoroughly read the assigned chapter material and work the odd problems at the end of the chapter. Although problems will not be graded, the process of doing them will provide an excellent learning review. If you have a need to turn them in you may do so on the last day of class. Remember, only the Problem Sets will be graded.

The student should master the terms and concepts found in bold in the text. Many students find it useful to rewrite lecture notes soon after class, and to outline the book chapters as they are studied. These rewritten notes and outlines can be very useful study tools

Be sure to study chemistry daily, it's hopeless to try to cram two or three weeks of material into one night of study before a test. To understand each new portion of material well, the student must have thoroughly learned all of the previous material. To be successful in chemistry you should commit to two extra hours of study for every hour your class meets.

The key to passing this class is to work problems. Do lots of problems. Work as many problems as necessary to understand a particular concept.

A study group of your peers is another way to master the material presented in this class. A group of three to five can provide that needed support.

GROUP ACTIVITIES: Group work is encouraged for the two graded problem sets, five exercises and the poster presentation. Although it is not required that an individual be in a group, it is highly recommended. A good study group can provide an additional resource for successfully completing this course. The maximum group size is 4 members. That means that the Problem Sets and Exercises can be turned in with only four names per project and that the Poster Presentation can only support four students. If you choose not to participate in a group throughout the semester (that is ok) you also must do the poster project by yourself.

RESERVE DESK: I will also try to make the materials available in word &/or pdf-files on the web. Included in these files will be an example of the mid- term test. Also answer keys to all the test will be made available on reserve.
