HOUSTON COMMUNITY COLLEGE-NORTHWEST PHYSICAL SCIENCE DEPARTMENT CHEMISTRY DIVISION CHEM 1412: GENERAL CHEMISTRY II Course Information: Spring, 2011 COURSE CALENDAR IS ATTACHED This course fulfills the following core intellectual competencies: 1Reading (Textbook and Laboratory Protocols); 2Writing (Laboratory Reports); 3Speaking (Laboratory Work Groups); 4Listening (Lecture); 5Critical thinking (Lab Data Analysis and lecture tests); 6computer literacy (computer assisted and computer simulated labs). (1) Dr. Pradip K Srivastava Telephone: 713-718-5857 Email: Pradip.Srivastava@hccs.edu (2) The HCC-Northwest Learning Web Site is now at http://learning.hccs.edu Select “Find your professor”. You can search for this course using my name: William Askew My name should appear. Select. Then Select the course. Course materials are listed including course power points, homework assignments, and test reviews. (1) TextBooks: Chemistry, Tenth Edition. Raymond Chang. McGraw Hill. You may use the ninth edition of this text. CHEMISTRY: CHEM 1412, General Chemistry II. New lab manual. (2) Course Grading System: (A) Lab. The lab grade will come from graded lab reports, pre lab tests, and a possible written lab final. o Each lab report will worth a specified number of points. The point value for each experiment is listed below. Lab reports should be completed individually. Review questions for each experiment will be due at the beginng of each lab meeting. o Pre lab tests may be given prior to the start of the lab. These tests will be short and worth only one-two points. The pre lab test points will be included in the lab report grade. You must be present to take the pre lab test. 10% of the lab grade will come from either assigned homework. Homework will be due at the start of class on the due date. (B) Lecture Course Information for CHEM 1412: Page 1 If the four lecture tests are taken, the lowest test grade will be dropped. The first test missed for any reason is automatically the test dropped. 3 tests: 300 total points Final exam: 100 total points Lab Grade: 100 points Max course points = 500 total A (90-100%) =450-500 total points B (80-89%) =400-449 total points C (70-79%) =350-399 total points D (60-69%) =300-349 total points F (0-59%) =000-299 total points (D) The final exam is a HCCS system final exam and is required. The final exam grade will not be dropped. (3) Honesty: Please be aware that the HCC rules regarding cheating will be enforced. Anyone caught cheating either will receive a grade of zero or be dropped from the course. (4) Makeup Tests/Labs: Makeup tests will not be scheduled. You may drop one of the four lecture tests. The first test missed for any reason will be the test dropped. Due to the large number of wet labs, makeup labs might not be possible. Don’t miss a lab. (5) ADA Requirements: The Houston Community College System obeys all ADA requirements. If you need assistance, contact the Disability Support Service Office at dsso.nw@hccs.edu or telephone 713-718-5422. (6) Students taking a class more than two times may face an increase in tuition as mandated by the State of Texas. Please don’t drop a class without careful thought. Tutors are available. (7) STUDENTS MUST WITHDRAW, OR BE WITHDRAWN, by the official withdrawal date, AT 4:30 PM. AFTER THIS DATE, YOU WILL RECEIVE A GRADE IN THE COURSE. (8) You will need to activate your HCCS student email account. Go to http://www.hccs.edu/hccs/current-students/student-e-mail for a tutorial and instructions for registration.
