[Florence Rocle]

Thelecture notes for the chemistry 100 hybrid class are accessed by clicking on the appropriate link below. Also included are links that provide answers and problem solving strategies to all practice problems in each chapter.

The course is given by Prof. Binyomin Abrams (section A4), Dr. Klaudja Caushi (section A2), Prof. Keying Chen (section A3), and Prof. Linda Doerrer (section A1). Discussion sections are led by a talented team of discussion leaders with the support of undergraduate learning assistants.

Prof. Keying Chen (SCI 452B) is in charge of the laboratory portion of CH102 as well as section scheduling. The labs are led by a talented team of graduate teaching fellows. (ISE 1 labs are led by Dr. Kristen Bushell)

All members of the course staff are available for consultation during their office hours. Attending office hours is the best way to get answers to your questions and get support in CH102. All students are welcome and encouraged to attend any of the office hours listed to discuss questions about the lecture/discussion portion of the course (questions about the lab portion of the course should be directed to the lab instructors).

Content-related questions, and logistics questions not answered in the syllabus, can also be posted to the Piazza online discussion forum. Piazza is a great way to collaborate with your peers and get support during times when there are not office hours (nights and weekends). The Piazza forum can be accessed at: ://piazza.com/bu/spring2024/casch102

If you have questions of a personal or private nature, please send them to ch102-q...@bu.edu E-mails sent to this address will reach all of the course instructors simultaneously, and the appropriate instructor will respond as soon as they are able. We ask that you please do not email course staff individually.

Please note: e-mail is not a replacement for attending office hours, and e-mail is not an effective way to get answers to content or logistics questions. While instructors will certainly respond to personal, private, and urgent matters by email, they will not answer content or logistics-related questions by email. Questions about content or logistics should be posted on Piazza or brought to office hours.

The following materials are all available at the Barnes and Noble @ Boston University. Students who completed CH101 in Fall 2023 should already have all of the materials that they require (provided that they purchased a full-year PointSolutions license).

A student solutions manual is available from the same sites as above. That said, we do not recommend purchasing the solutions manual for two reasons: (1) data collected from previous years has shown that students who use the solutions manual for studying score lower in the course(!) and (2) it contains numerous errors that can be very inconvenient. The solutions manual is a very ineffective, and potentially harmful, study tool. If you do choose to purchase it, suggestions for how to get the most out of the textbook and solutions manual are here. Instead of using the solutions manual: we highly recommend working in study groups and attending any of the many course office hours (i.e., free tutoring!).

Office hours (i.e., free tutoring): are a great way to get support in your work, learn more about chemistry, and get to know your peers and instructors. You never need an appointment or even a question, and all students are invited to attend any of the posted office hours (even with other instructors). Click here for the complete schedule of office hours.

Students are required to attend all of the sections (lecture, discussion, pre-lab lecture, and lab) for which they are registered. Unfortunately, given the large size of the course (more than 700 students!), we do not have the flexibility to allow students to switch between different sections. If you are registered for a section that conflicts with your schedule, please immediately correct your schedule so that you are able to attend all required sections.

Scheduling conflicts: if you are currently registered for a section that does not work with your schedule (due to conflicts), please unregister from that section to make room for students who can take that section. If all of the sections that work with your schedule are currently full, please add the appropriate waitlist section: AX is for lecture, BX is for discussion, MX is for lab, or PX is for pre-lab lecture. We will do our best to accommodate all students in these sections (though we cannot guarantee it).

There will be a total of five Monday-night quizzes, roughly every 2 to 3 weeks throughout the semester. The quizzes will be given on Monday evenings at 6:30pm. The quiz schedule includes the dates of the quizzes.

The 6th (and final) quiz will take place during the final exam period on Wednesday, 8 May 2024 at 6pm. The final quiz will be comprised of roughly 75% new material (since quiz 5) and 25% cumulative material, and the final quiz will last 2 hours. All students are required to take the final quiz in CH102 and it will only be given at that time.

Chemistry is a cumulative discipline, which means that the ability to learn later topics in the course (and in subsequent courses) is strongly tied to mastering prior topics. As such, each quiz will be cumulative, though most of the questions will be based on new material since the previous quiz. Do expect, however, that roughly 10-15% of each quiz (after quiz 1) will be cumulative material. The exact topic cutoff for each quiz will be posted at the end of the preceding week.

No one is perfect; moreover, there are many reasons why someone might have to miss a quiz (emergencies, close family events, illness, etc.). We get that! So this course is designed to take this into account: your quiz score in CH102 will be the average of your four best Monday-night quizzes and the final quiz. In other words: your lowest Monday-night quiz (not the final quiz) will be dropped. So please do not worry about missing (or doing less than great on) one quiz!

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.

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 science and, hopefully, chemistry. We intend to focus especially on what are the core ideas of chemistry.

The primary goal of the lab is to develop the skills necessary for work in upper-level science labs and research. Additionally, the experiments will highlight the concepts and ideas taught in the lecture and help students deepen their understanding of general chemistry.

Course grades are assigned based on the overall scores at the end of the course. The following (tentative) grading scheme will be used to assign course grades based on your score in the course. Please note that we reserve the right to lower cutoff numbers (making achieving a grade easier) but we will not raise them. However, please do not count on them changing.

Starting after quiz #2, we will provide each student with their "overall score so far." These overall scores so far will take into account all of the scores on the work completed so far (quizzes, labs, and participation) following the percentages listed above. In this way, you will have a measure of how you are doing at that point in the course.

Please note that the overall score so far will not take in account dropping of the lowest lab, dropping the lowest Monday-night quiz, accommodations for absences from lectures or discussion, or bonus points. This will all be done only at the end of the semester.

Example calculation: Consider, for example, a student with the following scores at some point during the course: 100% lecture participation and engagement, 100% in discussion participation, 80% quiz average, and 90% lab average. The overall score so far for this student would be:

Quizzes are graded and returned to the class immediately through Gradescope. We highly recommend that all students review their graded quizzes right away so that they can identify areas that still require improvement. As we said above, Chemistry is a cumulative discipline and so it will be important for students to attend office hours to address any areas of needed improvement! Since the quizzes are returned immediately, unfortunately that means that makeup quizzes are not possible. Please make sure to note the dates of quizzes in your calendar and make plans accordingly. Of course, it is perfectly reasonable that there may be a circumstance beyond your control that necessitates missing a quiz (emergencies, close family events, illness, etc.). We get that! So please do not worry about missing one quiz. If you miss one Monday-night quiz then that will be the quiz that is dropped at the end of the semester. All students must take the final quiz, which cannot be dropped.

Grading mistake? We do our best to make sure that all quizzes are graded fairly and accurately, though mistakes can occur with a class of this size. All of the grading rubrics will be visible on Gradescope so that you can check your work. To ensure fairness, all quizzes are graded with same rubrics, so requests for additional credit (beyond what is on the rubrics) for incorrect answers cannot be entertained. If you review your quiz and you believe that you answered a question correctly, but credit was not awarded: please print a copy of that quiz, annotate the question that you believe was graded incorrectly based on the rubric, and submit the printout to your teaching fellow (TF) at the conclusion of your discussion section the same week as the quiz. Regrade requests are only handled in writing and in this manner, and they are not accepted after the allotted time.
