XXXXX Course Pre-requisites A student may qualify for Chemistry 115 by 1. Attaining a minimum math ACT score of 26 or a minimum math SAT score of 600, or 2. Earning a grade of C or better in Chemistry 110B, or 3. Obtaining a minimum composite score of 24 on the QRA (math placement exam). Course Objectives Chemistry 115 is the first semester of a two semester course of study in the fundamental principles of chemistry. The course is appropriate for students who: 1. Want a basic knowledge of one of the physical sciences 2. Need to satisfy GEC objective #2B (including the lab requirement) 3. Need 115 to satisfy a requirement and/or prerequisite in their major 4. Intend to enroll in a professional school or program that requires additional study in chemistry The objectives of this course are to present the fundamental basis of chemistry upon which subsequent course work is built. Basic topics include, but are not limited to, atomic and molecular structure, the periodic table and periodicity, chemical stoichiometry, reactions (precipitation, acid-base, and redox), thermodynamics, and properties of gases, liquids, and solids. Laboratory experiments are designed to support the lecture topics. Expected Learning Outcomes Upon successful completion of this course, students should: know and correctly use the language of chemistry (nomenclature, terminology, and symbolic representations) understand and be able to apply chemical facts, concepts, and models, and be able to use them as a foundation to organize further chemical knowledge and to understand the physical world be able to visualize the structure of matter and its reactions at the atomic and molecular (microscopic) level and comprehend how these lead to the properties and behavior of bulk matter master qualitative and quantitative problem solving skills be able to use their knowledge to analyze and construct solutions for new and unfamiliar problems be able to solve quantitative problems using basic mathematical skills understand the nature and application of natural or physical sciences at a basic level sufficient to: conduct simple experiments to generate and analyze real data present data for analysis (e.g. using charts, graphs, tables) perform mathematical calculations appropriate for data analysis use abstract reasoning to interpret data formulate and test hypotheses with scientific rigor understand the complexities of scientific issues sufficient to think critically about the mutual impacts of science, society, natural resources, and the environment. General Education Curriculum Through its focus on the study of basic topics in chemistry and the laboratory requirement of conducting simple experiments, this course satisfies the GEC requirements for Scientific Inquiry (objective 2B): Use quantitative and scientific knowledge effectively. Textbooks Chemistry, by Gilbert, Kirss, Foster, and Davies (4 th ) Laboratory Experiments for General Chemistry 115, by WVU Staff (6 th ).

2 Calculators Homework Calculation of Final Letter Grade Only non-programmable calculators may be used during quizzes and exams. Scientific calculators ($8-$12) that perform all the needed mathematical calculations (including logarithms) are available at the WVU Book Store as well as at various other commercial establishments. Mandatory graded online homework assignments/objectives will be assigned using the Smartwork system and will count 10% toward your final numerical course average. Online homework is instantaneously graded and students receive immediate feedback. It is your responsibility to complete homework assignments by the deadlines set by your instructor. The textbook contains many questions and problems. Specific problems related to the material covered in lecture will be assigned as other homework. Although these problem assignments will not be collected and graded, they should help you understand the various concepts in lecture and thereby prepare you for the examinations. Answers to many of these problems can be found in the back of your textbook. Our object is to give you the best possible grade that can be justified by your achievement in the course. Final numerical averages will be calculated as shown below: Calculation of Final Numerical Grade Exams (4) 40% (10% each) Homework 10% Final Exam 25% Lab. Avg. 25% Attendance 0% or 1% bonus total. 100% In general, your the hourly exam average is the best indicator of your course performance. Experience has shown that if your hourly exam average is much higher than the class average, you are doing A or B work. If your average is comparable, you are doing C work. If your average is well below the class average, you are doing D or F work. Maximum numerical average cutoffs for each letter grade are 0-59% F, 60-69% D, 70-79% C, 80-89% B, and % A. Exam Formats The four hourly exams (20 questions) and the final exam (50 questions) are multiple choice and indicated answers will be graded as correct or incorrect. Hourly exams will be given in your assigned laboratory room during the first hour of a scheduled laboratory period. Any questions/ concerns/ errors regarding scores for exams, weekly homework, and laboratory unknowns should be addressed in person with your instructor within ONE week of posted grade. The schedule for exams is as follows: Fall 2015 Exams Exam Date Exam 1 Tuesday Sept 8 Exam 2 Tuesday Sept 29 Exam 3 Tuesday Oct 20 Exam 4 Tuesday Nov 17 Lab Final Tuesday Dec 10 Final Exam Tuesday Dec 15, 7-9 PM All sections of Chem 110B, Chem 115, and Chem 116 share this slot Everything in life comes to you as a teacher.

5 Chemistry 115 Laboratory Pre-Lab and Post-Lab Questions Lab Pre- Assessments Laboratory Conduct Policy on prior work Unknowns We wish for you to remain safe and leave lab at a reasonable time each week. This result is routinely achieved by students with a solid understanding of the safety concerns, techniques, and calculations involved in that week s lab activities. Before coming to the laboratory each week, you are expected to read the assigned experiment carefully and answer the associated prelaboratory questions in your lab manual. The post-lab questions (if any) are to be answered prior to the next laboratory session. Each week your TA will check your lab manual and record whether or not you have completed these questions. If you have, your grade is recorded as C, for complete, if not, you earn an I, for incomplete. Students that are absent for a lab, must still complete the associated pre-lab and post-lab questions. The TA will check these questions for completeness the next time the student attend lab. Students who routinely complete pre and post lab questions are rewarded with up to four (4) percentage points added to their lab average as shown: # of I s lab question completion bonus 0 4% 1 3% 2 2% 3 1% 4 or more 0% You will need to demonstrate an appropriate level of understanding about safety, techniques, and calculations involved by earning a minimum 8 0% laboratory pre-assessment score. These preassessments are provided on the ecampus page for your scheduled LAB section. They become available one week prior to your scheduled lab session and close at midnight the night before. Failure to obtain the minimum score will result in your exclusion from lab and an unearned absence. Each student is to do his/her own work in a quiet, efficient manner. The work area is to be kept clean and orderly. At the end of the laboratory period, the work area/sink should be clean and all common equipment should be returned to the common equipment container. The gas jets should be checked to ensure that they have been turned off. The student should inspect the desk area to ensure that no apparatus has been left out. Your teaching assistant (TA) will provide you with a tutorial at the beginning of each laboratory session. Students are expected to come to lab on time and listen and remain quiet until the tutorial is completed by your TA (lab drawers should NOT be open during this time); any questions should be directed to the TA at that the end of the tutorial. For safety reasons, all students must leave lab at the specified time. This means that you should begin cleaning up 10 minutes before the end of your lab period. If you have not completed the entire experiment, ask your TA or instructor about the best course of action. Bringing material from previous semesters, including lab notebooks, Data Report Sheets (DRS), etc., is considered to be a form of cheating and will not be tolerated. Any student caught with old laboratory material will be given a zero for the lab experiment and an unexcused absence (this includes the hallway outside of the lab rooms). Laboratory unknowns will be compared to known values. For quantitative unknowns, the closer the student s numerical answer to the known value, the higher the unknown score. Everything in life comes to you as a teacher. Pay attention. Learn quickly. Page 5 of 6

6 Only one attempt will be allowed for each unknown. Check any calculations carefully and account for significant figures and units before you hand in your results. These results should be handed in at the end of the period. Laboratory Average Calculation of Lab Average (worth 25% of final numerical average) Laboratory Experiment Average 65% (lowest lab grade dropped) Lab Final Exam 25% Lab Pre-Assessments & TA Evaluation 10% If a student completes all the laboratory experiments, the lowest achieved DRS score will be dropped. A score of zero due to an unexcused absence from lab will not be dropped. A comprehensive laboratory final examination will be given during the last laboratory period. Students should keep all returned laboratory experiments throughout the semester for study purposes. No make-up exam will be given for the laboratory final exam.
