UW CHEM 152 Autumn 2011 LEARNING OBJECTIVES The central ideas presented in this course are: Thermodynamics. We will begin the course by exploring the concepts of energy, enthalpy, entropy, and the Gibbs energy. The ultimate goal of this section of the course is to develop the tools that allow one to predict if a chemical reaction will be spontaneous. Electrochemistry. We will revisit "redox" chemistry previously described in CHEM 142, and use this reaction class as an opportunity to explore the thermodynamic concepts described above. Quantum Mechanics and Atomic Theory. In this portion of the course you will be introduced to the modern description of the hydrogen atom as derived from quantum mechanical principles. This description will be extended to other atoms, and eventually used to construct the periodic table of the elements. Bonding. Chemical bonds are "where the action is" in Chemistry. We will develop a description of chemical bonds (covalent, polar covalent, and ionic) and explore some simple models capable of predicting bonding patterns (Lewis dot structures) and molecular shapes (VSEPR). In the lab portion of the course you will conduct laboratory exercises that: Explore the concepts learned in lectures. Develop laboratory, data analysis, and scientific writing skills. COURSE COMPONENTS AND GRADING The course consists of: 3 lectures per week 1 discussion section per week 1 threehour laboratory session most weeks of the quarter (6 labs total) Daily work in the ALEKS online learning environment Online prelab and paperbased postlab assignments GRADING The point distribution for the evaluative components of the course is as follows: 2 Midterm exams (45 minutes each) Final exam (1 hour 45 minutes) Discussion section participation ALEKS Objectives & Final Assessment Laboratory TOTAL 40% 25% 10% 10% 15% 100% Grade Distribution. The final mean GPA in Chemistry 152 generally falls within the range 2.6 +/ 0.2. It is the Chemistry Department's policy not to make grade changes of 0.1 after final class grades are submitted to the UW Registrar. Page 2 of 9 UW CHEM 152 Autumn 2011 Your scores for the various assignments, reports, and exams will be recorded using the online Gradebook that is part of UW's Catalyst Web Tools. A link to the Catalyst login is available on the "Courses" page of the Chemistry Department's website: http://depts.washington.edu/chem/courses/. Late Policy. It is YOUR responsibility to monitor assignment deadlines posted in ALEKS and on the course and lab websites. No extensions will be given for ALEKS objectives, or for prelabs in Catalyst. For lab reports, refer to the policy pages in the lab manual. ACADEMIC ETHICS Original work performed in good faith is assumed on all assignments and course components. The Student Conduct Code (see http://www.washington.edu/students/handbook/conduct.html) outlines the following forms of academic misconduct: Intentional misrepresentation of credentials Falsification of data Plagiarism Failure to adhere to this code of ethics will result in prosecution as described in the Student Conduct Code. In short, if you have not done something yourself, do not attempt to pass it off as original work. If you have questions about what might cross the line, please do not hesitate to ask your lab or class instructor. It is presumed that the data you record and report in laboratory is your work. In addition, all data analysis and writing you submit should be yours alone, even if you collected data with a laboratory partner. We often find examples of plagiarism in which lab reports are copied from someone else, or from an earlier quarter. LECTURES Lecture Schedule. An approximate schedule for the chapters to be covered each week is at the end of this document. You are responsible for material covered in class AND in the textbook (whether or not it was covered in lecture). Lectures will cover only highlights of the textbook material. Lecture and Discussion Section Etiquette. Out of respect for your classmates, please observe the following rules: Arrive on time. If an emergency causes you to arrive late, please enter quietly through the rear doors of the lecture hall/classroom. Do not pack up your belongings before the end of class. Keep side conversations to a minimum. Keep your cell phone or pager on silent, and refrain from sending or reading text messages. Do not browse or read materials that are unrelated to the lecture. This includes but is not limited to newspapers, books, magazines, and the internet. DISCUSSION SECTION In the discussion section you will explore the concepts presented in the course. Specifically, you will collaborate with your colleagues on problems that will help you synthesize the material covered in the previous week's lectures. These problems will be graded on participation only (discussion section participation is worth 10% of your grade in CHEM 152). You must attend your discussion section to earn participation points. Punctuality. You must arrive to discussion section within the first five minutes of the class period to obtain participation points. If you arrive later than that, you will still be able to complete a worksheet with your group, but the worksheet will not be accepted for participation credit. Page 3 of 9 UW CHEM 152 Autumn 2011 ONLINE LEARNING (ALEKS) This course will use the internetbased learning program ALEKS (Assessment and LEarning in Knowledge Spaces). In ALEKS, you will complete learning objectives rather than traditional homework assignments. An ALEKS Objective contains topics relevant to the lecture discussions. ALEKS will present you with a series of problems that explore a particular topic. The problems will have enough variability that you will only be able to get them consistently correct by understanding the core principle or skill defining the topic. Once you can consistently get the problems for a given topic correct, ALEKS will conclude that you have learned the topic, and you will then be allowed to choose another topic to learn (refer to the ALEKS handout posted on the course website for more details). Your daily/weekly work on ALEKS will be on your own schedule outside of class, although there are specific deadlines by which you must complete various Objectives. Your first task in ALEKS will be to complete an Initial Assessment of your knowledge of math and chemistry. The assessment will contain 2530 questions and shouldn't take more than an hour to complete. You will probably be asked several questions that you don't know how to answer. Don't worry...the ALEKS system is only determining your knowledge baseline so that it can be tailored to address your specific needs. Every student will have a different assessment profile and will need to review different topics and skills. When you use ALEKS, you will complete the learning tasks you need and not those somebody else needs. After you complete the Initial Assessment, ALEKS will provide oneonone instruction tailored specifically to your needs. ALEKS will not allow you to begin working on course Objectives until you have completed the Initial Assessment. You are responsible for monitoring the due date and time for all ALEKS Objectives. It is not possible to start an ALEKS Objective 3 or 4 hours before it is due and still be able to complete it on time. ALEKS will not let you access the problems corresponding to the more advanced topics in an Objective until you have mastered the basics, so you will need to spend time nearly every day on ALEKS in order to complete the Objectives. The schedule of Objectives and their due dates is given at the end of this document. All Objectives will be due at 9:00 pm on the posted due date. EXAMS There are two midterm exams and one final exam in this course. The dates for these exams are provided in the course schedule at the end of this document. Chemistry knowledge is cumulative so questions on exams will often depend on knowledge from earlier chapters, including those covered in CHEM 142. Exam Protocol Bring a few pencils, your calculator, and a photo ID to all exams. You must sit according to the seating charts that will be posted on the course website prior to Exam 1. Grading Exam scores will be posted in the Catalyst GradeBook. Graded exams will be returned during your discussion section. Keys to exams will be posted on the CHEM 152 course website/bulletin board. Regrading (applies to Lab Reports and Exams) If it is a simple addition error, show the report to your TA for correction. Regrade requests must be for 5 pts! To have an exam or lab report regraded, it must be given to your TA within 48 hours of its return to you along with a note specifically explaining what you want re graded. We reserve the right to regrade the entire exam or lab report, so you may lose rather than gain points. Note that we will be making copies of a subset of the exams and will compare your exam to the copy of the original. Any discrepancies will be treated as academic misconduct. Page 4 of 9 UW CHEM 152 Autumn 2011 Absences If you are absent from a midterm examination through sickness or other valid, unavoidable cause, your performance on the final exam will be used to construct a score for the missed exam. Examples of unavoidable causes include: illness; death or serious illness in the immediate family; and with prior notification observance of regularly scheduled religious obligations, attendance at academic conferences or field trips, or participation in universitysponsored activities, such as debating contests or athletics. Absence due to participation in universitysponsored activities require PRIOR approval (please do this during the first or second week of the quarter). Bring a letter from your coach or organizer along with your schedule for the quarter to Dr. Tracy Harvey in Bagley 303D. If you have an unanticipated absence from an exam, you must do the following: 1. Report your absence from an hourly examination within 72 hours to Dr. Tracy Harvey in Bagley 303D ([email protected]), and 2. Provide proof of your unavoidable cause (a doctor's note, an accident report, a memorial folder, or similar documentation). The documentation must include a contact name and telephone number. 3. Dr. Harvey will notify the instructor of the status of your absence. If your absence does not meet the above criteria, you will be given a zero for the exam. Note: If you are absent from the Final examination, and you are ineligible for an incomplete according to UW regulations, a course grade of 0.0 will be given. If an incomplete is given, you must take the final exam for the same course in the next regular academic quarter in which it is offered to remove the incomplete. There are no exceptions to this rule. LABS Each experiment consists of a prelab exercise, lab work, and postlab report. The lab schedule is provided at the end of this section. Participation. If you miss more than one lab in Chem 152, you will receive a grade of 0.0 for the course. The same polices described about unavoidable causes for missing an exam apply to labs. If an absence is unavoidable, please contact the stockroom (Bagley 271, [email protected]) as soon as possible and we will try to schedule you into an alternate lab session. If there is no alternate time available, contact Dr. Harvey, Bagley 303D ([email protected]) by the end of the week following your absence in order to be scheduled for a makeup lab. If you have an anticipated conflict with one of your lab sessions, you will be allowed to reschedule into another lab session if one is available. Rescheduling must be done in advance of your regularly scheduled lab session. If you cannot reschedule an anticipated absence in advance or you have a last minute unexcused absence (e.g., you are more than 10 minutes late to lab, forget to go to lab, or sleep through the lab session) you will receive a grade of 0 for that experiment. Read the policy pages in the lab manual and also consult the "Frequently Asked Questions for Labs" available online via the "152 Labs" link on http://depts.washington.edu/chem/courses/. Safety. You are required to follow the safety protocols outlined in your laboratory manual. In particular, you are required to wear approved safety goggles and a lab coat during all the experiments. If you do not dress appropriately, you will not be allowed to attend the lab session. No opentoed shoes, no bare legs or ankles will be permitted, nor will any clothing that interferes with lab activities. Prelabs. The information necessary to prepare yourself for each lab is available online via the "152 Labs" link at http://depts.washington.edu/chem/couses/. This course uses internetbased prelabs exclusively. The prelab exercises are accessed online via links on the course website. Check the due dates and times for the prelabs in order to avoid being shut out you alone are responsible for completing the assignment before the deadline. Page 5 of 9 UW CHEM 152 Autumn 2011 You must score >0 points (out of 5 total) on the prelab before the deadline. If you don't have the required >0 point score by the deadline, 15 points will be deducted from your lab grade at the end of the quarter. Purpose/Procedure. The purpose and procedure sections of your notebook must be completed before the start of your lab session. This requires that you read through the online lab information and the experimental procedure in the lab manual in order to summarize, in your own words, the goal and general procedure for the experiment. Do not copy the overview or purpose sections (or any other prose) from the online lab information, the lab manual, or from other students that is plagiarism. See the lab manual for more details. Lab Notebook. Bound laboratory notebook (not loose leaf) with numbered pages and carbonless duplicate copies are available at the bookstore. Please note the special nature of this lab notebook. All recording and reporting must be in this notebook in ink. Draw a neat line through your errors instead of erasing or whiting out. You should still be able to read the mistake...just in case! On the first available page of your notebook write (i) your name and student number, (ii) Autumn Quarter 2011, (iii) the course number, and (iv) your section letters. Use the second page as a table of contents which you will fill in as you complete experiments in this course and subsequent courses. Write your name, section, and experiment number on each page you use. Be prepared to hand in the duplicate pages at the end of each lab period. During Labs. Perform only assigned work during the lab section in which you are enrolled. Record observations (what you see) and data (what you measure), perform all necessary calculations, and come to some conclusion based on your results. Before You Leave the Lab. Your TA will check to make sure that you have done all assigned work, cleaned up your station, and returned all equipment to the stockroom and/or your drawer. Your TA will ask for the duplicate pages of your work for the day and any completed lab reports, if applicable. PostLab Reports. The postlab report instructions (and deadlines) may be accessed online via the "152 Labs" link on the following website: http://depts.washington.edu/chem/courses/. Lab Schedule.

If you can't attend the office hours for your own TA and need help outside of discussion section and lab, please be sure to visit the other TAs in their office hours (as posted on the course website). Instructors: See instructors' office hours and contact information on the front page of this document. Catalyst Discussion Board: The online discussion board is a space where you can discuss course material with your colleagues any time day or night. Your fellow students: Through the online discussion board and through study groups you organize. Center for Learning and Undergraduate Enrichment (CLUE): Drop in tutoring SunThurs evenings and exam reviews (visit http://depts.washington.edu/clue/index.php for details). Chemistry Study Center (CSC): Open study area with computers for working on ALEKS and other course assignments; located in BAG 330, available MonFri 8:30 a.m. to 4:30 p.m. Undergraduate Services, Bagley 303: The staff can help with scheduling problems, academic advising, or other administrative issues that arise during the course. KEYS TO SUCCESS 1. Attend ALL classes, pay close attention, and take notes. 2. Learning chemistry is a sequential process. You must understand today's material before you can understand tomorrow's. As with all courses at UW, your instructors and TAs will assume that you are studying at least two hours for each hour of lecture and one hour for every hour of lab. Find a place that allows for periods of uninterrupted study. Skim through chapter or sections to be covered in the next lecture. 3. Make daily, weekly, and quarterly learning plans and follow those plans. 4. Practice! Work many problems focus on understanding the concepts and general processes, not just memorizing how to solve a specific problem. 5. Talk chemistry with fellow Chem. 152 students. You will not only learn more, but you will probably also enjoy the course more. CLUE and the library are good meeting places DISABILITY RESOURCES If you would like to request academic accommodations due to a disability, please contact Disability Resources for Students, 448 Schmitz, 2065438924 (V) or 2065438925 (TTY). If you have a letter from Disability Resources for Students indicating you have a disability that requires academic accommodations, please present your letter to Prof. Drobny in person within the first two weeks of the quarter to discuss your accommodations. If you require accommodations in the labs, please present your letter to Dr. Tracy Harvey in person within the first two weeks of the quarter to discuss your accommodations.
