C. Graham Brittain Page 1 of 8 9/8/2009 Introductory Chemistry ~ CHM 103 Course Information & Syllabus ~ Fall Semester, 2009 Instructor Cindy Graham Brittain, PhD Email: [email protected] Phone: 401-874-2028 Office: Pastore 215B Office Hours: posted at http://www.chm.uri.edu/chm105/index.html Required Lecture Materials • Custom textbook: General, Organic and Biochemistry (Denniston/Topping/Caret) • ARIS Online Study System at: http://highered.mcgraw-hill.com/classware/infoCenter.do?isbn=0073511102 (Student Section Code for Section 002 on T Th: D3B-7D-C7D) (Student Section Code for Section 003 on MWF: 86D-8D-46D) • Scientific calculator (with log and exponent functions) – NO OTHER electronic devices may be used in class. Calculators will NOT be provided, and students will NOT be permitted to share calculators during quizzes or exams. • Additional materials at the CHM 103/105 course website: http://www.chm.uri.edu/chm105/index.html Students are expected to print their own copies of course documents and carefully study ALL posted lecture materials. Class Meetings Section 002: T Th 3:30 – 4:45 PM Pastore 124 Main Lecture Hall Section 003: M W F 2:00 – 2:50 PM Pastore 124 Main Lecture Hall Grading Policy Each student’s course grade will be based on the following: 3 Lecture Exams (18% each) 54% Unannounced Lecture Quizzes 14% ARIS Online Skill Checks 14% Comprehensive Final Exam 18% 100% The grade for any one of the three Lecture Exams that is missed (OR substantially lower than the Final Exam) may be replaced by the Final Exam score. Thus the Final Exam may count as much as 36% of a student’s overall grade. NO extra credit assignments will be given, and the standard grading scale will be in effect: 90%+ = A, 80-89% = B, 70-79% = C, 60-69% = D, <60% = F. Grades in the CHM 103 lecture are earned by demonstrating mastery/proficiency in the required skills; these skills include problem-solving, critical thinking, and the ability to apply course concepts within relevant scenarios. To be clear: Each student’s grade is determined by the quality of that student’s performance on the lecture course work items. The grade is not open to negotiation, and it is not dictated by what’s needed to progress in the student’s chosen program of study. The grade must be earned by achieving proficiency in (and ideally, mastery of) the skills identified as essential to ongoing success in the student’s degree program. The purpose of using the Final Exam as a replacement for a missed Lecture Exam is not to boost each student’s overall average. Instead it is to eliminate the need for make-up tests for any students who are absent on the day of a Lecture Exam. ALL students MUST adhere to the exam schedule specified on the syllabus. NO make-up exams will be given, and students should NOT inquire as to whether they may be given a make-up test. Alternate testing will be available for students who provide documentation from the Disability Services Offices that indicates a scheduling conflict or the need for private testing and/or additional time. Alternate test arrangements for these students (or for those participating in University-sanctioned events or observing religious holidays) MUST be made at least one full week prior to the scheduled exam. Students should anticipate that graded exam papers will be returned in class approximately one week after the exam date, and should not inquire as to the status of their test papers. If the Kingston campus is closed due to weather (or other unexpected event) on a scheduled Lecture Exam day, students should anticipate that the exam will be given at the next class meeting.C. Graham Brittain Page 2 of 8 9/8/2009 Lecture Work Items: 1. Lecture Exams Lecture exam questions will have a variety of formats, including short answer, fill-in-the-blank, essay, and problem-solving. The questions will come directly from the content presented and discussed during lecture, and are likely to be similar to the required problems in the ARIS online study system, the recommended problems in the textbook, and the old exam questions posted on the course website. Students should commit to working as many of these homework problems as possible as practice for taking exams; the goal is to become confident and efficient at analyzing and solving problems. Students who get the MOST practice solving problems tend to have the greatest success in this course. Guidelines for Solving Problems: SIX Steps you should ALWAYS perform when working a Chemistry Problem 1. Translate the word problem by identifying (and writing down) what is GIVEN, and what is UNKNOWN. 2. If a mathematical formula is needed to solve the problem, show the formula (example: PV = nRT). 3. Substitute in the numerical values WITH their UNITS. (Numerical values have NO meaning without their units.) 4. Carefully and systematically CHECK THE UNITS all the way through the problem to ensure that the calculation has been set up correctly. Don’t EVER assume that the units of the final answer will be what you intended. Check them to make sure! If the intermediate units don’t cancel properly to yield the desired units in the final result, then you’ve made an error in setting up the calculation. Go back and look for the error! You’ll be able to catch and prevent frustrating and costly mistakes if you take a moment to check your units. Even after you’ve entered all of the numerical values into your calculator and computed the result, you still have TWO more steps to perform: 5. Carefully consider the numerical value of your result. Does it make sense to you? Does the value feel right? Were you expecting a larger number than the one that’s shown on your calculator? Or a smaller number? If the number seems odd to you, check your work AGAIN! Check the algebra you used to rearrange the formula to solve for the unknown variable. Double-check the units of every value. Then try entering all of the numbers into your calculator a second (or even third) time to verify that you haven’t made an error in pressing the buttons of the functions or numbers. 6. Finally, round the value of your result according to the rules of significant figures. Remember that this value is only as “good” as the numbers you used to calculate it. And remember to report the final result with its units.
