Three lectures, one laboratory, one recitation. Only one of Chemistry 1, 11, or 16, may be counted for credit. Textbook: Brown, T. L.; LeMay, H. E.; et al. Chemistry: The Central Science, 14 th Ed.; Pearson Education, Inc.: USA, 2015. You are welcome to use previous editions of the textbook, but you must purchase the 14 th Ed. access code for Mastering Chemistry. Our course code for Mastering Chemistry is MCPALLUCCIO02322. Please register and enroll in the course ASAP by following the prompts at http://www.masteringchemistry.com/site. Attendance: Your attendance at each class period is expected. You are responsible for all material covered in lectures, including assigned readings, Mastering Chemistry assignments, and recitation worksheets. If you miss a class, it is your responsibility to obtain all information given out in class. Some of the information provided in class, but not necessarily all, will be available on the course website (https://trunk.tufts.edu). Academic Integrity: Academic honesty must be adhered to for all aspects of the course including all exams, laboratory assignments and reports, attendance, and homework. Tufts University has an official policy on academic integrity, according to which the use of materials not directly authorized by the instructor during exams or submitting a fraudulent exam regrade petition will result in a failing grade for the course without the possibility to withdraw from it. Any paperwork and/or lab reports that are found to be identical will each be given zero points. Incidences of cheating will not be tolerated regardless of how minor they are. Violations will result in a 0 for the assignment or exam and will be reported to the Dean for appropriate action. 1
Grading: Course grades will be evaluated based on the following: Exam I June 4 th 200 pts 20% Exam II June 18 th 200 pts 20% Final Exam (cumulative) June 28 th 250 pts 25% Homework 150 pts 15% Laboratory 200 pts 20% Total 1000 pts 100% The final course grade will be assigned according to the Tufts University grading scale given below: A+ 96.67 100% B+ 86.67 89.99% C+ 76.67 79.99% D+ 66.67 69.99% F 0.00 59.99% A 93.33 96.66% B 83.33 86.66% C 73.33 76.66% D 63.33 66.66% A 90.00 93.32% B 80.00 83.32% C 70.00 73.32% D 60.00 63.32% Exams: Two in-class exams and one cumulative final exam will be held during the summer session. Make up exams will generally not be given and are in no way guaranteed. If you have a conflict with a scheduled exam, you must contact me well in advance. Remedies for an excused absence will be handled on a case-by-case basis. Excused absences include only those for medical reasons (obtain a note from physician), family emergency (obtain note from the Dean), or participation in an official University sanctioned activity (obtain note from the sponsor/director). Otherwise, making up an exam is not an option and you will receive a grade of zero. If the average exam score in the class is below 75%, the scores will be scaled up to such that the class average is 75%. If the average score of the class is 75% or above, the scores will not be scaled down. The exact conversion scheme (from raw to scaled score) will be announced after each exam, so that you are aware of how you are doing at any time during the course. If you believe that an error was made in the grading of an exam, you may submit the exam, together with a written description of the error(s), to Dr. Palluccio for regrading within two days after the graded exam was available for pick up. Please note that whole exam may be regraded, and your score may be changed accordingly (up or down). I reserve the right to assign seats during an exam. Homework: Problem sets will be assigned regularly and will be completed through the online program, Mastering Chemistry (http://www.masteringchemistry.com/site). The assignments and due dates will be announced on the course website. In general, electronic homework will contain problems of a straightforward nature to aid in developing the basic problem-solving skills. To supplement this, recitation worksheets with more rigorous problems will be available through the course website (see next section). Students may work together but each student must turn in their own assignment. Direct copying of solutions is viewed as a violation of academic integrity. Students are also not allowed to refer to solution manuals or previous years answer keys or assignments (such violations will be considered a violation of the honor code). Late homework assignments will NOT be accepted. In calculating the final homework grades, all points for electronic problem sets are added together; there is no scaling or weighting of individual assignments. 2
Recitation: Recitations are one hour problem solving sessions (held 2x per week) run by teaching assistants (TAs). Recitation attendance is generally optional * though it is highly recommended you attend as your TA is an additional resource that can help clarify any difficulties you may encounter with lecture topics/electronic homework/recitation worksheets. Recitation worksheets containing additional practice problems will be available on the course website before the scheduled recitation period (they will not be turned in or graded; they are simply additional practice problems for you). You should show all work that was done to arrive at the answer. It is your responsibility to check your work with the posted answer keys to make sure your answers are correct. Extra credit assignments will not be offered. * Some recitation sessions may be mandatory as I may use them for additional lecture time. You will be notified at least one day in advance of a mandatory recitation period. * The recitation and laboratory teaching assistant information (including office hours) will be announced and posted on the course website at the end of the first week of classes. Laboratory: In order to receive a passing grade in the course, you must pass the laboratory portion with an average of at least 60%. The laboratory guidelines are provided in a separate syllabus, which will be handed out to you. Your lab grade will be scaled up or down to account for the differences in the rigor of the laboratory teaching assistants. Please note your lab grade is determined by your laboratory instructor, not your lecture instructor. If you have questions regarding a lab grade, you must direct them to your lab instructor. There are no make-up laboratories. Prior to each laboratory period, you must read the experimental handout and any relevant chapters in the lecture text. Additional details concerning the laboratory can be found in the laboratory syllabus. You will be expected to visit the course website (via Trunk) often for updates regarding lab and to download experimental handouts. Please note you need to purchase lag goggles and a lab notebook from the Tufts bookstore before the first experiment. Additional Information: For additional help with this (or any) course, students may contact the Academic Resource Center: https://students.tufts.edu/academic-advice-and-support/academic-resource-center. I am unable to write recommendation letters for students enrolled in Tufts summer sessions. 3

Strategies for Success in CHEM 0001/0002 There is no single method that works for everyone but here are some helpful tips and what pitfalls to avoid. (1) Attend class and be prepared to participate. Performance drops off precipitously with each lecture missed. If you miss a class, get notes from a classmate. Do not just rely on PowerPoint slides (if any). There will be a lot of material covered in class that is not on the PowerPoint slides. Work out examples on your own before I do. We will do many problems in class. I will give you time to work them out on your own before I go over the solutions do them! Even if you get them wrong, you will learn from your mistakes. Don t text in class! Not only is it disrespectful to your instructor, it will take your focus away from the material being covered. Even if you think you can text and pay attention, you cannot! You re brain doesn t work that way. (2) Briefly review lecture topics/text before lecture. Be familiar with what material is going to be presented and be prepared to ask questions. (3) Take accurate notes in class, both from what is written & what is said. Note the important stuff. (4) Review or summarize class notes as soon as possible after class. Make note of what topics are unclear and get them clarified through reading the text, asking questions, and/or coming to office hours. Always reread the text after lecture to improve on your understanding of concepts just discussed. (5) Do not simply memorize facts. There will be some limited memorization required but the majority of the class will focus on applications of ideas and concepts. Students that simply memorize notes and problems typically score no higher than a C and often end the semester with a D or F. (6) Invest time every day into this class (at least 10 hours per week). The vast majority of learning in the class has to come from you working outside of lecture. Do not expect that by attending lecture you will pass. Study time should be distributed evenly throughout the week. Simply studying the night before a problem set or exam is not enough. (7) Understand concepts behind homework problems, don t just memorize equations. One of the goals of the course is to help students develop problem solving skills so that you are able to solve any sort of problem, not just those covered in class. (8) If something is unclear, get help as soon as possible! The material within the course continually builds upon previously discussed concepts. Concepts from the early part of the semesters are used in subsequent classes and courses. The material presented in this course form the foundation from which all subsequent chemistry classes are based on. 5
