Discussion sections are led by Senior Lecturer Natalya Bassina (SCI/270A, 617-353-4716, firstname.lastname@example.org) email@example.com), and graduate teaching fellows, with help form undergraduate learning assistants. Natalya Bassina also is in charge of class scheduling and other administrative aspects of the course.
The text for this course is based on an abridged, custom edition of the Canadian text Mahaffy et al., Chemistry: Human Activity, Chemical Reactivity, second edition, ISBN 9781305284203. We have arranged for the online edition to be available from its publisher for $88.30 (less than 1/3 of the cost of the original text purchased from the bookstore). Earlier editions of this textbook, including the custom first edition, are no longer being used and so may not be substituted for the required second edition. There are three options to buy this text package, listed in order of increasing cost.
Option 1, $88.30: This option must be purchased online directly from the publisher and includes the online version of the text only and access to online activities. The online course key is E-X7FG5BHX6XWLR. This option does not include a physical copy of the text. To purchase this option, go to http://www.cengagebrain.com/course/2357698. Should you also want a printed copy of the current, second edition text, you may purchase instead Option 3 below or a used copy available at various places (ISBN 9781305284203). Whether you buy a hard copy of the earlier edition is optional.
Option 2: $114: This is the same online-only Option 1 above (again, with no physical copy of the text) purchased from the Boston University Barnes & Noble Bookstore.
Option 3: $198: This option includes the printed version of the text in addition to the online materials in Option 1 above. It must be purchased from the Boston University Barnes & Noble Bookstore.
In addition to the text package above, the following seven items are required:
Be aware that it is a Massachusetts State Law that safety goggles are mandatory in the laboratory. In the lab, all students who wear contact lenses should wear prescription glasses under their safety goggles. Contact lenses are forbidden in the lab. Also, all students must wear the appropriate clothing: long pants, long sleeves and closed shoes (no sandals or flip-flops).

The course consists of five required components:
There are three hours of lecture meetings each week, and these lecture meetings are held in SCI/109 at four alternative times:
You are required to attend your assigned lecture meeting.
There is a one-hour discussion each week, on Thursday or Friday. Discussions meet starting Thursday, September 7.
There is one three-hour laboratory each week. There will also be a laboratory lecture, on Wednesday–Friday. These laboratory lectures are:
Pre-Lab lectures begin the second week of the semester. The first laboratory lecture is on Wednesday, September 13. You are required to attend your assigned pre-lab lecture meeting. Labs begin the third week of the semester on Monday, September 18. You are required to attend your assigned lab.
The Monday 6:30–8:30 pm sessions are used only for the lecture exams and the lab exam. On lecture exam days there will be no Monday lecture (sections A1, A2, and A4) and the preceding Thursday or following Tuesday evening lecture (section A3) will be shortened to 30 minutes; the section A3 lecture that will be shortened will be announce the week preceding the exam; there will be no A3 lecture on Tuesday, November 21. For the lab exam, lectures will be held as usual.
If you have not yet registered for all of the five components of the course (three for CH103), please do so right away. All grade records are based on the registrar information, so we require that you be officially registered and that you attend the corresponding lecture, discussion and lab.
There will be three lecture exams, a lab exam and a course final exam as follows:
Exams are given only at the scheduled time. A missed exam counts as 0. In particular, please note the following:
Quizzes will be given during each lecture. These quizzes are meant to assess your preparation for the material to be covered that day in lecture. If you are absent, the missed quizzes count as 0. No makeup quizzes will be given. The lecture quizzes count for a total of 10% of your course grade.
Unannounced quizzes will be given in discussion. Each discussion quiz will count equally. These quizzes are meant to assess your understanding of topics covered in previous lectures and homework. If you are absent, the missed quiz counts as 0. No makeup quizzes will be given. The discussion quizzes count for a total of 15% of your course grade.
We require that no electronic devices (cell phones, computers, tablets, etc.) may be used in lectures, discussions, and labs.
To help you get the greatest benefit you are able to during these class times.
All students at Boston University are expected to maintain high standards of academic honesty and integrity. It is the responsibility of every student to be aware of the Academic Conduct Code’s contents and to abide by its provisions, as detailed at

We have designed the course as an introduction to general chemistry that integrates laboratory explorations with the development of the analytical tools necessary to understand and guide those explorations. Some particular aspects that we will emphasize are
Our goal is to help you share in our excitement for and the wonder of science, to challenge you to excel, to give you a sense of empowerment about science, and to encourage you to continue study in scienceand hopefully chemistry. We intend to focus especially on what are the core ideas of chemistry.

The detailed laboratory schedule is here.
The laboratory part of the course will let you see first-hand chemical principles and processes in action. It will also give you experience with some of the methods scientists use to do chemical research. Your laboratory will consist of the following.
Your scores for each part of the course will always be available to you on Blackboard, at http://goo.gl/LKSSne.
We do not assign letter grades to exams, labs, or quizzes. We only assign a course grade. This course grade will be determined based on your overall course score. This score is determined as follows:
|Contributions to overall course score|
For CH101 students, the lab score counts for 20% of your course grade. The various components of the lab will be graded as follows: The lab experiments (30 points for each lab period), lab quizzes (10 points each), pre-lab lecture quizzes (5 points each), and the lab exam (60 points). Lab quizzes are given at the beginning of each lab to check your familiarity with the basic features of the lab to be done.
CH103 (lecture-only) students will graded based on their relative score for the lecture-only part of the course: Lecture exams count as 30/80 * 100% = 37.50%, the final exam as 15/80 * 100% = 18.75%, lecture quizzes as 10/80 * 100% = 12.50%, discussion quizzes as 15/80 * 100% = 18.75%, and ALEKS as 10/80 * 100% = 12.50%.
No makeup quizzes will be given. A missed discussion quiz counts as 0. The lowest discussion quiz score will be dropped. A missed lecture quiz counts as 0. The lowest three lecture quiz scores will be dropped. A missed lab counts as 0. The lowest score for the one-period lab experiments will be dropped. The missed two lab period experiment can be made up at the make up lab week at the end of the semester. If, due to unusual circumstances, such as prolonged illness, you miss more than one lab, please contact Dr. Golger (firstname.lastname@example.org) (email@example.com) as soon as possible so that special arrangements can be made to catch up with your work.
There are no fixed percentages of A grades, B grades, etc. Rather, we assign course letter grades based on our assessment of how someone should have performed to receive an A, B, etc. Based on past experience, it is likely that the average grade in the course will be in the C+ range.
After each exam we will provide the distribution of overall course scores so far, on a 1000-point scale, and your individual score so far. These overall scores will take into account the scores on the work completed so far (lecture quizzes, discussion quizzes, labs, and exams). In this way, you will have a measure of how you are doing at that point in the course.
Any question concerning the grading of a lecture exam, quiz, or laboratory report must be brought to the attention of your discussion or laboratory teaching fellow during the class session in which it is returned to you; material will not be accepted for regrading afterwards.
Indicate on the face of the exam, quiz or laboratory report the questions you wish re-graded and your reasons for believing that they were misgraded. The entire work will be re-graded. Be sure you have made no alterations in your work. We occasionally photocopy your graded work as a check. Please note that the penalties for academic misconduct are severe, as detailed in Boston University's Academic Conduct Code,
CH101 is prerequisite to CH102. To continue to CH102, a grade of at least C- in CH101 is required.
Learning chemistry requires persistence, diligence and hard work. We suggest that you plan to spend about 15 hours per week on this course over and above the scheduled class contact hours. If you are willing to devote this time, and you spend it wisely and effectively, you will be able to perform your best. In an effort to provide some more specific guidance, we offer detailed suggestions here
The teaching staff will hold office hours throughout each week. These and many others resources are detailed here
If you are experiencing difficulty, please come to see your lecture professor or Professor Golger without delay. Often, students in this course perceive that they are doing poorer work than they actually are. Particularly for first-year students, we recognize that it may be difficult for you to judge your academic standing in the course, since we do not use the same type of grading scheme with which you may be familiar from high school. That is why it is important for you to speak to us before making any major decision, such as dropping the course.
If dropping the course appears to be in your best interest, we still would like to work through the decision with you. We are also happy to advise you on appropriate choices for your academic program. If you drop the course by Tuesday, October 10, no record of it will appear on your transcript. After that date, until the end of the day Friday, November 10, you may drop the course but with a W grade (withdrawn). If you must drop the course, note that CH101 will be given during the Spring and Summer sessions of 2017.
