Bunker Hill Community College General Chemistry II CHM202 H1 Class Syllabus Spring 2019 (Subject to change) INSTRUCTOR: Bruce Lapierre: Desk location H184; Conference hours by appointment. Office hours vary and are posted weekly on the class website Website www.thelapierres.com/chm202 E-mail bdlapier@bhcc.mass.edu TEXT: The Biology and Chemistry Department has partnered with our textbook publishers and the BHCC Bookstore to provide exactly what you need for this course at a significantly discounted price. If you purchase your course material from a vendor other than the BHCC Bookstore you may receive the wrong textbook edition. Chemistry: The science in context, 5 th Edition, Gilbert et. al. (2018) Student Solution Manual: Chemistry, 5 th Edition, Wile (2018) (recommended) Please note that CHM202 does not require a digital access code, and only the textbook is required. EQUIPMENT: Safety Glasses Must meet ANSI Z87.1-1989 standard. The bookstore has approved safety goggles available for purchase at a price comparable to other vendors. If you choose to use goggles other than those available in the bookstore, you must have them approved by me. Scientific Calculator Graphing capability not necessary any brand is acceptable. It must have both natural logarithm and base-ten logarithm capability for CHM202 ATTENDANCE POLICY: Attend all classes and laboratory sessions. Arrive on time and remain to the end of class. Inform me beforehand if you cannot be present or on time. If this is impossible, please see me at your first opportunity to explain your reasons. I may require you to show documentation. If I do not excuse your absence, you will receive a zero for work missed. Excessive absences, late arrivals and/or early departures excused or unexcused will result in failure. INSTRUCTION METHOD: Question and Answer at the start of every class. Lecture-discussion every class covering new material. Laboratory as scheduled. HOMEWORK & RECOMMENDED STUDY PROCEDURES: Complete the homework problems. Do not limit yourself to these problems complete more if you need the practice. The quiz and test problems will be similar. Read the assigned sections to prepare for class. There will be a quiz on the homework at the start of class. Read and understand the laboratory theory and instructions prior to scheduled labs. HOMEWORK QUIZZES: There is a very brief quiz at the start of class if you had a homework assignment. You may use your notes, but you may not use your book, phone or computer. These quizzes will consist of three to five questions from your homework assignment. You are permitted to consult a handwritten notecard no larger than 5 x 8, and you may write on both sides. You may also refer to your written homework assignment if you had one. If you miss the quiz for any reason, your score will be zero. There is no makeup. TESTS: There are two multiple-choice tests for each unit. The first is a take-home test with questions and problems that will be like those on the unit test. The purpose of this test is to prepare you for the unit test described below. You may consult any source available for this test (except me), including study groups and tutors. This test must be submitted prior to the unit test. If you are unable to attend the unit test, you must still submit your take home before the deadline. Email it or pass it in early. NO LATE SUBMISSIONS WILL BE ACCEPTED.
The in-class test for each unit will be held when the unit is completed. You are permitted to consult a handwritten notecard no larger than 5 x 8, and you may write on both sides. Notecards are subject to inspection before and during the test. I will also publish a practice test for the unit and provide the solutions. It is similar in content and format to the takehome, unit test and makeup. I do not collect or correct this test. MAKEUP TEST: There is no makeup for the take home test. If you are absent for the unit test, and I have excused your absence, you may make up the test on the date and time given in the syllabus. If you are unable to attend either, you will be required to submit documentation of the reason(s) for your absence to make up the test. If you are unhappy with your grade for the unit test, you may take the makeup test, and your grade will be the higher of the two test scores. GRADES: Your grade in this course will be computed as follows: Unit Grades (total) 75% of the final grade Laboratory Achievement 25% of the final grade Homework Quizzes up to 5 points extra credit Each Unit Grade is computed as follows: Unit Test/Makeup Test (higher grade of the two) 100% of the unit grade Take Home Test up to 5 points extra credit CHEATING POLICY: I encourage you to work together on the take home test, but simply copying the answers will defeat its purpose. Otherwise, you are expected to complete all work on your own. This does not mean that students should not study together a study group is a very useful tool in learning. Work on lab reports (see below) and unit tests, however, is to be performed individually. If you violate this policy, you will be excluded from class and receive a failing grade for the course. Cheating is the unauthorized exchange of information between students. Both the student receiving the help and the student providing it are guilty of cheating. TECHNOLOGY POLICIES AND LIMITATIONS: You may not use notebook computers or tablets during class. If you feel you need to use a device, see me for an exception. Permission to use such devices during class may be granted only by me, and my decision is final. Recording devices and pocket translators are permitted with my approval. Calculators are required, but relevant equations may not be stored in memory. Your calculators are subject to examination. You may not use your phone for any purpose during class or lab. Silence it! LABORATORY GUIDELINES: Several laboratory experiments are scheduled during the semester (see the class schedule below for details). The following requirements and guidelines apply to all labs and lab reports. General: All labs are performed in room. Report to the lab on time. There is no break during lab. If you must leave for any reason, speak to me first. It is unwise and, more importantly, unsafe to leave an experiment unattended for any length of time. Absolutely no food or drink (including bottled water) is permitted in the lab. Safety glasses must be worn at all times. No student will be admitted to the lab without safety glasses. Your safety glasses must be approved before the first lab. A locked drawer will be provided for you to store your safety glasses in the lab if you wish. Loud, boisterous or otherwise unruly behavior is unacceptable. Working surfaces must be clear of extraneous materials at all times. Laboratory exercises are designed to be completed in the allotted time. If you fail to complete the work, your work will be graded based on the work you have completed.
Laboratory Procedures: You are required to read the theory and procedures for each lab before reporting to the lab. This is impossible if you wait until five minutes before the lab to print the instructions. At the start of each lab, there may be a few minutes set aside to discuss any special considerations, such as changes to written procedures or any tips that may help you to spend your lab time more productively. You will work in groups of 2 or 3 people in the lab. You may choose your own lab partners, but all groupings are subject to approval. It is important that you share the work in the lab. If you fall into the common trap of allowing one person to make all the decisions, perform all the procedures and make all the observations, you will not learn anything. Participate and don t be bullied. If you and your lab partners disagree on the meaning of the procedure, ask for clarification. DO NOT ARGUE WITH EACH OTHER. It may help to remember that in any argument, at least one person is wrong Be sure you are working with clean glassware. Unless you are otherwise instructed, wash and rinse all glassware prior to using it. Give it a final rinse with distilled water before you use it. It is usually not necessary to dry glassware before using it. Deposit laboratory waste in the proper receptacles. Waste chemicals usually need to be treated before disposal. Although treatment is not your responsibility, you are responsible for depositing used chemicals in the designated containers. If there is an accident in the lab, notify me immediately. Record all data and observations in pen on the official data sheets at the time the observation is made or the measurement is taken. If data are recorded improperly, points will be deducted. Perform only the necessary calculations during the lab session. Leave all other calculations until you get home. This will help you maximize your laboratory time. Summary: BE ON TIME!!! Put away your phones. Follow all safety procedures. Stay in the lab. Notify me if you must step out. Do not sit and watch. Participate. If you find the directions unclear, ask for help. Be careful and patient. Finish on time. Clean up after yourself. Laboratory Reports: Although your lab grade contributes only 25% to your final average, you must pass the laboratory component. If you fail the lab, you fail the course. A word file is provided, but you must enable editing in order to preserve the formatting and structure of the report. Fill in all fields in the report. If any fields are left blank, the report is incomplete and will be graded accordingly. You must submit all lab reports in pdf format as a single, properly named file. The file naming convention for each lab is explained on the lab s web page. Reports must be submitted by email before the deadline. Detailed instructions for creating pdf documents for submission are provided on the web page for each lab. Submit the actual pdf and not a link to your cloud storage. I will accept no reports submitted in another format. I will accept NO GOOGLE DOCS. A late report may be penalized substantially if it is submitted after the deadline. No lab report will be accepted for credit after the date of the Unit 4 Test (NOT the date of the Unit 4 Makeup). It is proper for all members of a lab group to have the same data. Your calculated results will be the same if you calculated them correctly. However, if you have made a calculation error, used a formula incorrectly or made any other type of error, it is unlikely that you and your lab partners will get the same answer. Do your own calculations copying is cheating! The questions are intended to check your knowledge of chemistry as it relates to the topic of the laboratory investigation. You are expected to answer these questions on your own. These questions are not intended to be group projects. Once again, copying is cheating. You are not expected to add anything to your lab report that is not specifically required. Your conclusions are contained in the results and the answers to the questions. If you want to change your report in any way, feel free to do so. Your final submission will be graded. If your amended report is late, your entire report is late.
The minimum grade for the lab report is 70% if you: report on time to the lab; stay until the end; participate fully in the exercise; record your data properly; submit your report on time; and submit a complete report. Check your report before submitting it. If you have failed to fill in a field, your report is incomplete.
