COURSE DESCRIPTION The course consists of: o 3 lectures a week o 1 quiz section a week o 1 three-hour laboratory session most weeks of the quarter (6 total). Attendance at ALL course components is essential to obtain a satisfactory grade in this course. 2 COURSE OBJECTIVES The central focus of this course is to develop quantitative problem solving skills. You will: ? Learn to clearly pose a problem with detailed solutions for all aspects of that problem. These can include central and auxiliary equations with any needed conversion factors. ? Learn to report precision input data in solutions to problems (contains the appropriate number of significant figures). ? Use these skills to master the following fundamental chemistry topics: ? the atomic nature of matter ? stoichiometry ? major classes of inorganic chemical reactions ? gases ? chemical equilibrium ? acids and bases ? applications of aqueous equilibria ? Conduct laboratory exercises that: ? emphasize and apply the concepts learned in lectures. ? develop laboratory, data analysis, and scientific writing skills. ACADEMIC ETHICS Original work performed in good faith is assumed on all laboratories/exams/worksheets. It is presumed that the data you record and report in laboratory is your work. University rules (Handbook, Vol. IV, Part 9, Chapter 1, Executive Order #61) define scientific and scholarly misconduct to include the following forms of inappropriate activities: ? Intentional misrepresentation of credentials ? Falsification of data ? Plagiarism Failure to adhere to this code of ethics will result in prosecution to the fullest extent (see http://www.washington.edu/students/handbook/conduct.html for specifics). In short, if you have not done something yourself, do not attempt to pass it off as original work. GRADING 2 midterm exams (50 min. each) 30 % Quizzes (lowest quiz score dropped) 8 % Homework (lowest HW score dropped) 8 % Clicker Questions 4 % Laboratory 20 % Final exam (1 hr. 50 min.) 30 % TOTAL 100 % Grade Distribution ? The undergraduate program committee policy states that the final mean GPA in Chemistry 142 should fall 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 Records. 3 Late Policy - No extensions are given for WebAssign assignments. For lab report policies, refer to the front pages in the lab manual. LECTURES An approximate schedule assigns chapters to be covered each week is on page 8. You are responsible for material covered in class AND in the textbook. Attendance at lectures is expected. 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 where available. ? Do not begin to pack up your books etc. before the end of lecture. ? Do not have conversations with your neighbor during lecture. ? Turn off your cell phone or pager. CLICKER INSTRUCTIONS Clickers are an audience response system that uses similar technology to what you may have seen on TV game shows. During lecture, your instructor poses a multiple choice question within a PowerPoint slide in front of the classroom. Click your reply (just like a T.V. remote) from anywhere in the classroom by selecting a letter or number response on your clicker that corresponds to one of the answer choices on the slide. Your response is sent to a wireless receiver, collected and then sent to the classroom computer. There is a little LED light on the upper left side of your clicker. After you?ve sent your reply, the light will turn green for a short time to signal that your answer was received and stored. NOTES: ? Where to purchase a Clicker: University Bookstore ? Clicker ID Code: Each clicker has a unique 6-digit identification alphanumeric code, located immediately below the bar code on the back of the clicker. Codes usually begin with ?0? (zero) or ?1?and may contain the letters A-F (since there are no letter ?O?s, all ?0?s are the number zero). This Clicker ID code is used to match your clicker responses to your name for grading purposes. You will need to enter this code in WebAssign (in the lecture section) in an assignment called ?Clicker Registration I?. Note that if the code is entered incorrectly or is missing, you will not be able to receive any points toward your clicker score. ? Lost Clickers: Remember to bring your clicker to every lecture. If you lose your clicker, you need to buy another one at the bookstore and register the new Clicker ID code. You will need to enter this code in WebAssign (in the lecture section) in an assignment called ?Clicker Registration II (lost clicker)?. ? Clicker Grades: Periodically (usually once a week), clicker grades for each lecture will be posted on the Catalyst Gradebook (or WebAssign) so that you can check if your clicker responses are being received properly. Responses will be counted as 2 points if correct and 1 point if incorrect. Therefore, you will have some points even you answered the questions incorrectly. Responses will start counting toward the clicker portion of your grade in the class sometime in the 2nd week (the exact date will be announced in class). The lowest 3 lecture scores (as a percentage) will be dropped from your clicker grade. As a result of this policy, there will not be any accommodations made for excused absences from lecture. In other words, if you have to miss a lecture for whatever reason, 4 you should still be able to obtain the maximum points because you can simply drop the scores of the missed lectures. ? Setting the Frequency Channel: The clickers come already set to the default frequency channel of ?41?. If your LED light blinks yellow and then red while answering a question in class, it usually means that you need to reset the frequency channel. Perform these steps: 1. Press and release the ?GO? button. 2. While the LED light is flashing red and green, enter ?41?. 3. Press ?GO? again and the LED will show a solid green light for 3 seconds indicating that the channel has been reset. The LED will show a red light if unsuccessful. ? Batteries: Clickers are powered by two coin cell CR2032 (3.0V) Lithium Batteries. Batteries typically last for more than one year. Note that when you obtain a new clicker, you will need to remove the plastic strips from the battery contacts in order for it to work. ? Help station: If you need help with your clicker, bring it to the stockroom (BAG 271). There is a station set up there to help diagnose problems. LABS The lab consists of a pre-lab exercise, lab work, and post-lab report. The lab schedule is given on page 9. Attendance: You must attend every laboratory session. If you miss more than one lab without an excused absence, you will fail the class. The same polices described for missing an exam apply here. If you do miss lab, please contact your TA (if possible in advance of the lab) and the stockroom (Bagley 271). We will try to schedule you into an alternate lab time. See Dr Harvey, Bagley 294, if you need to be excused (there is no alternate time, or you need to be assigned a make up lab). See the laboratory manual for more details. Safety: There is an element of hazard in any laboratory course. You are required to follow the safety instructions as 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 open-toed shoes, no bare legs or ankles will be permitted, nor will any clothing that interferes with lab activity. Pre-labs: The information necessary to prepare yourself for each lab is available via the 142 Lab link on http://depts.washington.edu/chem/courses/. This course uses internet-based pre- labs exclusively. You will both receive and submit your assignments online via the internet. For more details, see the WebAssign description under homework. Check the due dates for the pre-labs to avoid being shut out. You must score at least 3.5 points (out of 5 total) on the WebAssign pre-lab before the due date, which is set to coincide with the first scheduled lab period of the week. If you don't have the required 3.5 point score by the due date, you will have 10 points deducted from your grade for the lab report. The purpose and procedure sections of your notebook must be completed before your lab session. 5 Lab Notebook: Bound laboratory notebook with numbered pages (not loose leaf) 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. Line through your errors neatly instead of erasing or whiting out. ? On the first page of your notebook write (i) your name and student number, (ii) Winter Quarter 2009, (iii) the course number, Chem. 142A, and (iv) your section. ? Start the experiments on page 2. ? 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. If any deviations are necessary, consult your TA first. Record observations (data), perform all necessary calculations, and based on your results, come to some conclusion. Before You Leave the Lab: Your TA will check and make sure that you have done all assigned work He/She will initial your lab notebook and ask for a duplicate copy of your work. Post-Lab Reports The report templates are available via the 142 Lab link on http://depts.washington.edu/chem/courses/ Exp. #1: Safety Exercise Physical Measurements and Error Analysis.

The remainder of the quiz section is devoted to helping you with difficulties in understanding the lecture and lab materials. HOMEWORK This course uses internet-based homework exclusively. You will both receive and submit your assignments online via the internet. Assignments will be available at least one week before they are due. You are responsible for determining the due date and time for all homework. In addition, internet-based services generally do not employ an atomic clock to determine the time; therefore do not wait until the last second to turn in your work! The internet interface is called ?WebAssign? and can be found at http://www.webassign.net/washington/login.html. How to access WebAssign: 1) Go to www.webassign.net/washington/login.html 2) Click on the button labeled ?Log In? which takes you to the UW NetID weblogin page: UW NetID: Password: 3) Click on the ?Log In? button which takes you back to WebAssign.

EXAMS Your UW Net ID (e-mail address without the "@u.washington.edu") Your UW Net ID password 7 There are 2 midterm exams and a final. The dates for these exams are provided in the schedule of lectures on page 8 of the syllabus. Chemistry knowledge is cumulative so questions on exams will often depend on knowledge from earlier chapters. Exam Rules 1. Bring a number 2 pencil, your calculator, and a photo ID to all exams. 2. You must sit according to the seating charts, posted on the walls in the front of the classroom a few days before the exam. Grading ? One hour exams will be graded and returned in quiz section. ? Keys to exams will be posted on the Chem 142 bulletin board in Bagley Hall and also on the class web site. Re-grading (applies to Exams and Lab Reports) ? If it is a simple addition error, show the exam/report to your TA for correction. ? Regrade must be for ? 5 pts! To have your exam/report re-graded, it must be given to your TA within 48 hours of its return to you along with a note explaining what you want re-graded. ? We reserve the right to re-grade the entire exam/report, so you may lose rather than gain points. Note that we will be Xeroxing a subset of the exams, and will compare your exam to the Xerox of the original. Any discrepancies will be treated as academic misconduct (see above). Absences If you are absent from a midterm examination through sickness or other valid unavoidable cause, the weight of your final exam will be increased proportionately in calculating the course grade. Examples of unavoidable causes include: illness, death or serious illness in the immediate family, and, provided previous notification is given, observance of regularly scheduled religious obligations and attendance at academic conferences or field trips, or participation in university-sponsored activities such as debating contests or athletic competition. Athletes, bring a letter from your coach with your schedule for the quarter to Dr. Tracy Harvey in Bagley 294. Proper Procedures: 1. Report your absence from an hourly examination within 72 hours to Dr. Tracy Harvey in Bagley 294, and 2. Bring proof of your emergency (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 the 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. Keys to Success 1. Attend ALL classes, pay close attention and take notes. 2. Chemistry is sequential and hierarchical. You must learn and digest today?s lecture before you can expect to understand tomorrow's lecture. Study at least two hours for each hour of lecture. Spend 8 one hour studying 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 plans and follow plan. 4. Practice what you are to do on the exams. Work many problems. 5. Talk chemistry with fellow Chem. 142 students. The study center (Bagley 330) is a good meeting place. Use your instructor, TA and the study center tutors as resources.
