OBJECTIVES: Chemistry 115 is the first half of the two semester General Chemistry course designed for science majors. If you are uncertain whether you have been properly placed in this class, please talk to your professor or advisor.

Lab is a co-requisite for all students except for those repeating the course. Those repeaters opting not to retake the lab are cautioned that their grade will be determined exclusively by quiz and exam performance.

The course is taught with the following objectives in mind:

1. To show the relationship that exists between physical and chemical properties in matter.

2. To help you develop skills needed to solve chemical problems in both, qualitative and quantitative manner

3. To provide a molecular world view, an outlook unique to chemistry and essential to an educated person.

4. To prepare you for subsequent high level chemistry courses.

quizzes or exams.

PREREQUISITES: Eligibility to take Chemistry 115 is based on eligibility to take MATH 185, a grade of B or better in second semester high school chemistry and an ACT composite score of 22 or higher. You are responsible for checking your eligibility and credential to take this course. If you do not meet ANY of these requirements, this course will be a nightmare and should consider seriously taking CHEM 111 instead.

EXTRA HELP: 1. We proudly announce that this year, our class will have two Peer Learning Assistants leading regular study groups.

2. A list of tutors, who can be hired for an hourly fee, is available in CB 100.

3. Both your lecture instructor and laboratory TA have posted office hours.

EXAMINATIONS: Chemistry 115 exams 1-3 will be given on the following days at

CB 153. All the exams will consist of both multiple-choice questions and composite questions. Exam 1 Friday, September 18, 6:30 – 7:20 PM Exam 2 Friday, October 23, , 6:30 – 7:20 PM Exam 3 Monday, November 30, , 6:30 – 7:20 PM FINAL Monday, December 7, 8:00 – 10:00 AM You are only required to take TWO out of total three mid-term exams. If you selected to take all three mid-term exams, two highest scores will be recorded for your semester final grade. For each examination you need to bring four items: 1) A calculator. You are prohibited to share calculators during an exam. Electronic devices (other than calculators) are prohibited during an exam; 2) A NMSU scantron, and 3) appropriate #2 pencils to circle your answers on the scantron. Please use only #2 pencils for all scantron responses; and 4) A valid NMSU student ID to each exam. Students with a valid NMSU ID will not be permitted to take the exam. The final exam will contain three sections with each section covering materials in each of the midterm exams.

All the exams, including the final exam, will be given at thescheduled times. The exams will not be administered at a different time, whether before or after the scheduled exam

time. If you cannot make it to any of the midterm exams, whether for an excused or unexcused absence, you could simply take the other two mid-term exams, as you are not required to take all three mid-term exams. If you miss two midterm exams, you should talk to me and seriously consider dropping the course. If you miss the final exam, you will be given a zero for that exam unless you request an “Incomplete” before the exam (see “Incomplete” on the next page for details).

HOMEWORK: There are three types of homework that we have designed to enhance your learning experience for this class. 1) The first type of homework is located at www.masteringchemistry.com. You will need to enroll in our class on masteringchemistry.com in order access the homework

there. Our course ID on masteringchemistry.com is Course ID: FEI4EIF15C115. You will need to enter correctly your NMSU 9-digit ID number. Please choose your login name to be “Your last name_Your first name” and use your NMSU email as your login email. If we cannot recognize your login name and email, we cannot let you enroll in the class on masteringchemistry. You are responsible for checking the due dates of each assignment on masteringchemistry.com. Please stay organized. Your first homework for credit on masteringchemistry.com is due on Aug 24; this homework is designed to serve as an introduction to masteringchemistry. Please note that some assigned homework on Masteringchemistry website are mandatory questions for credits and will contribute to your final grade; Other homework are designed as practice questions that will not bear credits for your final grade but are nevertheless useful questions to prepare you for exams. For credited questions: while you can submit after the deadline, late homework will be penalized: 5% score will be taken off for each hour of a late submission. For each question, you have up to three trials. Incorrectly answering a multiple-choice or true/false question before the last attempt will lead to some point deduction: for multiple-choice question, deduction per incorrect answer is 100%/(# of answer options - 1); for other types of questions, the deduction is 3% for each incorrect attempt. We strongly recommend you to review lecture materials, and finish assigned readings before you start doing the homework. Some questions have some hints to help you solve this question; if you opt to not

4

open the hints and answer the question correctly, there will be 2% bonus points. Homework for this category has a 90% mastery threshold. This means that if you score at or above 90% on the online homework at the end of the semester, you will receive a grade of 100% for this portion. Lower grades are scaled accordingly. This is to accommodate any technical issues, and possibly unforeseeable reasons (e.g., sickness). 2) The second type of homework is located on the Canvas site of NMSU (https://nmsu.instructure.com/login/ldap). Most of the homework here are composite questions. Therefore, you are required to show ALL your work of calculations, analyses, and evaluation clearly on your notebook. All answers must be supported by work clearly shown, and possibly complemented by an explicit explanation in words of how the results were arrived at. Please submit your work electronically via Canvas before the due time (e.g., you can scan your answers on your notebook, or simply take a picture of your answers). Your work will be checked for completeness, but not correctness. Please pay close attention to the due time of each assignment below and on Canvas. Late assignment will penalized by deducting 50% of points per day. Since composite questions in the exams will be highly similar to questions in the homework and/or questions discussed in class/workshop, it is to your advantage to take these questions very seriously and aim for thorough and in-depth understanding. In order to accommodate technical issues and unforeseeable reasons (e.g., sickness), you are required to submit at least 13 out of 15 weeks in order to receive full points for this portion in your final grade.

3) The third type of questions are assigned end-of-chapter questions to complement the other two types of homework. This homework assignment will not be turned in or graded but you are required to complete all homework and make sure that you fully understand how to solve each question. Most of the questions have answers found at the end of the textbook. You can always turn them in for evaluation of your skills. You could either work by yourself or work in groups on your homework assignments. In either case, please have a notebook to write down all your work for each of the assigned homework questions.

LABORATORY: Safety goggles must be worn whenever laboratory work is in progress. Goggles that will fit over most prescription glasses are available in the bookstore. Check with your TA before purchasing goggles so that you will obtain acceptable ones. Contact lenses should not be worn in the Laboratory. Safety policy also requires that you wear shoes that cover your feet (no open sandals) and either long pants or a lab apron, which protects your legs. In the event of an accident it is far better to spill caustics and acids on clothing than directly on skin. Only students who have excused absence(s) will be allowed to make up an experiment. If you have to make up a lab, we encourage you to do it by attending the other lab section of the same week. Alternatively, you can make up a lab during the make-

7

up week (see schedule). Overall, if you miss more than 2 experiments during the semester, your grade for the course will be an F (or N), no matter what your exam scores are. Laboratories not made up will result in a deduction from the laboratory grade. You must have permission from your Teaching Assistant before a lab can be made up. Please bring all your questions regarding the laboratory component of the class directly to your teaching assistants (TA). Your TA will likely have more details for you on your first day at your lab session.

STUDENT CODE OF CONDUCT:

Please review the student code of conduct in your Student Handbook.

DISABILITIES and DISCRIMINA-TION:

If you have or believe you have a disability that interferes with your performance as a student in this class, you are encouraged for academic reasons to discuss this on a confidential basis with the instructor and /or the Director of Disabled Students Program (phone: 646-6840, TTY:646-1918) and/or the Americans with Disabilities Act (ADA) coordinator (tel. 646-7795). Appropriate accommodations may be provided for you. NMSU policy prohibits discrimination on the basis of age, ancestry, color, disability, gender identity, genetic information, national origin, race, religion, retaliation, serious medical condition, sex, sexual orientation, spousal affiliation and protected veterans status. Furthermore, Title IX prohibits sex discrimination to include sexual misconduct: sexual violence (sexual assault, rape), sexual harassment and retaliation. For more information on discrimination issues, Title IX, Campus SaVE Act, NMSU Policy Chapter 3.25, NMSU's complaint process, or to file a complaint contact: Gerard Nevarez, Title IX Coordinator Agustin Diaz, Title IX Deputy Coordinator Office of Institutional Equity (OIE) - O'Loughlin House, 1130 University Avenue; Phone: (575) 646-3635 E-mail: equity@nmsu.edu; Website: http://www.nmsu.edu/~eeo/ Other NMSU Resources: NMSU Police Department: (575) 646-3311 NMSU Police Victim Services: (575) 646-3424 NMSU Counseling Center: (575) 646-2731 NMSU Dean of Students: (575) 646-1722

For Any On-campus Emergencies: 911

WITHDRAWALS & "I" GRADES:

Students are sometimes confused about the requirements for a grade of "Incomplete", assuming it is a "late W". No withdrawals from individual courses are allowed after the mid-point of the semester (Oct 19, 2015). "I" grades can be given only after the mid-point of the semester. To receive an "I" the student must be passing the course with 70% or better at the midpoint of the semester and then be prevented from completing the course successfully due to illness or a family crisis. The student must provide documentation that the illness or family emergency makes it impossible for the student to complete the course with a passing grade.

GRADE: Two Mid-term Exams………............................40% Final Exam…………………………….………25% Lab experiments……………... ........................ 20% Masteringchemistry homework ........................10% Others (canvas homework, clicker questions and attendence, in-class quizzes) ………………………….……5% Total ............................................................... 100%

Students who are retaking Chem 115 may be excused from the experimental laboratory if their previous lab grade was 75 or better. A student desiring to be excused from lab must discuss this possibility with his or her lecture instructor before the end of the first week of the semester. Previous lab grades can be obtained from records kept in Room 100. Grades for students who have been excused from lab will be determined as follows.

Two Mid-term Exams………............................50% Final Exam…………………….………………35% Masteringchemistry homework ........................10% Others (canvas questions, clicker questions and attendence, in-class quizzes) ………………………….……5% Total ................................................................. 100%

Previous lab grades will NOT be counted. Students who took the lab prior to the Spring 2014 semester must take the laboratory portion of the course again.

The letter grade for the course will be given based on the standard percentage scheme:

Guaranteed grade cut-offs > 90 % A-/A

9

> 80 % B-/B/B+ > 70 % C-/C/C+ > 60 % D-/D/D+ < 50% F

ATTENDANCE CANVAS CLASS ANNOUNCEMENT WHAT TO BRING TO LECTURE CLICKERS

Attendance is important! It is assumed that every student is present at every class and lab. Therefore YOU ARE RESPONSIBLE for all announcements and for all material covered in class, whether or not the topic is in your text. It is YOUR RESPONSIBILITY to obtain missed lecture notes, copies of handouts, any announcements as to changes in problem sets, etc. Attendance will be taken every class with the clickers and attendance will count towards to final grade. Student must be present for entire class period to receive the whole amount of attendance points. Clickers will also be used for in-class quizzing and polling during lecture. Students caught with two clickers (one theirs, one another student’s) will be treated in accordance to University policy. Canvas site of this course is available at https://learn.nmsu.edu/. It is your responsibility to familiarize yourself with Canvas. Please take the Canvas Student Orientation if you need (https://training.instructure.com/courses/347469). Please check the Chem 115 course on Canvas daily, as I will be placing useful materials including announcements and some lecture notes. Students are encouraged to check the Canvas site of this course as well as their NMSU email addresses frequently as instructors often use these to communicate important course information. Should you have a preferred email address, you can forward your NMSU account to the preferred account so you do not miss any important announcements. You can arrange this yourself through myNMSU. It is not the instructor’s responsibility to set up a preferred email account for you. 1) One notebook designated for taking notes and completing in-class exercises, and 2) your clicker. If you have a cell phone, do not bring it to class. Be courteous to your fellow students. If you must bring it, turn it off and switch to airplane/silent mode!! CELL PHONES ARE NOT PERMITTED AT ANY EXAM. An RF Response Pad (clicker) is required for this lecture (clickers are used for quizzes, in-class participation, and especially

10

attendance). After purchase of a clicker from the bookstore, please register your clicker on the Canvas site for this course by entering the 8-digit iclicker remote ID on the iclicker tab of the course Canvas site (See the figure below). Purchase and registration of the clicker must be done before Monday, August 24, 2015. Attendance and quiz grades will be permanently recorded from this point on. If your clicker fails or you forget it, you will receive a zero grade for this lecture period, so do NOT forget them and check batteries before going to class. Have back-up batteries handy. Thus, forgetting your clicker or your clicker not working are not allowable excuses. The Department of Chemistry and Biochemistry did not design the clickers, so we cannot fix them if they do not work. You will have to contact the company to fix the problem. If you have problem registering your cliker on Chem115 course site on Canvas, please contact learning@nmsu.edu or 6-1840.
