This thick book will be used for the entire year's sequence of classes: Chem 142, 152 and 162. You may instead prefer to purchase the thin Chem 142 ONLY version, which contains only Chapters 18 and 20 from the full book. One version or the other is required. Note that thin versions are also available for the followup classes: Chem 152 ONLY and Chem 162 ONLY. Each thin version has the advantage that it is much easier to carry around than the thick version. Note too that the thin Chem 142 ONLY version's price also includes a Student Solutions Manual (which is helpful but optional). The optional Study Guide, Chemical Principles, 6th ed., Zumdahl/Kelter is also not required, but helpful. UW General Chemistry 142 Laboratory Manual, Autumn 2011Summer 2012.

COURSE COMPONENTS: Attendance at ALL these is essential to obtain a satisfactory grade in this course: UW CHEM 142 A Autumn 2011 LEARNING OBJECTIVES The central focus of this course is to develop quantitative problem solving skills. You will: Learn to solve word problems which require combining chemical and/or physical laws (e.g., mass balance for each chemical element) with simple math skills. Central to this is learning how to convert definitions (of things like moles, molarity, pH, equilibrium constant) into useful equations (involving numbers given in the problem) or units conversion factors, and to organize these into a logical, stepbystep solution to the overall word problem. Learn to apply this skill to essentially create and solve your own word problems in order to determine the desired unknown quantities based on your own laboratory measurements, and to report these with the appropriate number of significant figures. Master the following fundamental chemistry topics, and the use of the tools (equations) they provide for quantitative problem solving: the atomic nature of matter stoichiometry and balancing chemical equations classes of inorganic chemical reactions gases chemical equilibrium acids and bases and their titrations applications of aqueous equilibria Conduct laboratory exercises that: emphasize and apply the concepts learned in lectures and the problem solving skills learned from the concerted combination of lectures and homework. develop laboratory, data analysis, and scientific writing skills. GRADING The point distribution for the evaluative components of the course is as follows: 2 Midterm Exams (50 minutes and 20% each) Final Exam (1 hour 50 minutes) Discussion section participation ALEKS Objectives & Final Assessment Clicker questions (Lowest 3 days' scores are dropped) Laboratory TOTAL GRADE 40% 25% 5% 10% 5% 15% 100% Grade Distribution. The final mean GPA in Chemistry 142 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. 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. Page 2 of 11 UW CHEM 142 A Autumn 2011 ACADEMIC ETHICS Original work performed in good faith is assumed on all assignments and course components. It is presumed that the data you record and report in laboratory is your work. All writing you submit should be yours alone, even if you collected data with a laboratory partner. It is common that we find examples of plagiarism in which lab reports are copied from someone else or from an earlier quarter. These are automatically forwarded to a review committee on academic conduct. The Student Conduct Code (see http://www.washington.edu/students/handbook/conduct.html) includes the following as 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 syllabus. 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. Clickers : Part of your grade comes from your participation in Lectures, as judged from your Clicker scores. 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 5% of your grade in CHEM 142). 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 11 UW CHEM 142 A 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. Note that even if a deadline for an Objective has passed, you must still complete it before you can move on to the current Objective. For this reason, it is highly advantageous for you to keep up with the pace, meeting each ALEKS Objective's deadline on time. 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. You must register for ALEKS and complete the Initial Assessment by 11:00 pm Friday Sept. 30th. 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 due date, which is posted within ALEKS on the web Buying ALEKS for the whole year: Students who purchase ALEKS for the full academic year have access to ALEKS for chemistry for 42 weeks, using it in Chem 142, 152, and 162, and they will not be asked to pay again. Your next course's instructor will simply give the students the new course code when they want you to get started. Students just click "Options," "Change course code," and then enter the new code, effectively moving themselves from a section of 142 to a section of 152 (for example). Page 4 of 11 UW CHEM 142 A Autumn 2011 CLICKERS and CLICKER QUESTIONS and your inclass responses to them: Clickers are an audience response system that has been proven in educational research to be a very effective mechanism for improving learning in lecture classes. They use 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. Note that, as long as time remains to answer a clicker question, you can change your answer as many times as you like: your last answer will be the one recorded. Where to purchase a Clicker: University Bookstore (often they run out for the first few days of class, so call first before making a special trip there to get one). Keep them after this class, since they are required in other classes too. Clicker ID Code: Each clicker has a unique 6digit identification alphanumeric code ("device ID"), located immediately below the bar code on the back of the clicker. Codes usually begin with "0" (zero), "1", or "2" and may contain the letters AF (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 student number for grading purposes. You must register your clicker ID via Catalyst Web Tools before Oct. 5 (and again if you need to buy a replacement clicker midquarter due to loss or failure of your clicker). To register your clicker ID, use the following link: https://catalyst.uw.edu/webq/survey/earnshaw/144113 This will direct you to a login (with your UW Net ID) that contains a stepbystep procedure that will allow you to enter your clicker ID and match it with your student ID. Both numbers must be entered exactly correctly or you will not receive credit for clicker responses. That is, if the ID 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 using the same link as above. Turn in lost clickers to the Instructor or to BAG 271. 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. 2. 3. Press and release the "GO" button. While the LED light is flashing red and green, enter "41". 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 batteries. Batteries typically last for more than one year, but sometimes new clickers come with bad batteries. Note too 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. Clicker Help station: If you need help with your clicker, bring it to the UG stockroom (BAG 271) to help diagnose problems. Clicker Grades: Periodically (usually once a week), clicker grades for each lecture will be posted on the Catalyst Gradebook 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 get half credit even if you answer the question incorrectly. Responses will start counting toward the clicker portion of your grade in the class on Oct. 7. The lowest 3 lecture scores (as percent correct) 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, you should still be able to obtain the maximum points because you can simply drop the scores of the missed lectures. Page 5 of 11 UW CHEM 142 A Autumn 2011 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. Exam Protocol Bring a few # 2 pencils, a couple of Scantron forms, your calculator, and a photo ID to all exams. Submitted Scantron forms must be filled out completely. Any identifying information (name, student number, section letters, and test version) that is missing or incomplete will result in a 5point deduction from your exam score. All answers must be reported on the Scantron form by the end of the exam in order to be graded. You must sit according to the seating charts that are posted on the course website prior to each exam. Grading Exam scores will be posted in the Catalyst GradeBook. Scantron reports will be returned during your discussion section. Keys to exams will be posted on the CHEM 142A bulletin board near the coffee shop in Bagley Hall. Regrading (applies to both Exams and Lab reports) If it is a simple additionofgrades error, show the report to your TA for correction. Regrade requests must be for 5 pts! To have a 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 regraded. We reserve the right to regrade the entire report, so you may lose rather than gain points. For questions about machinegraded exams, contact your TA within 48 hours of receiving the Scantron report from your TA. Absences at Exams 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...
