This is a common exam for all Chem 101 sections and is written by all the instructors. Hour Exams: * * * * * * * * * * * * * * * * * * * The four hour exams, each worth 100 points, will be held in class on the following days: EXAM I Wednesday, Sept. 25 EXAM II Friday, Oct. 18 EXAM III Wednesday, Nov. 13 EXAM IV Friday, Dec. 13 Your exam point total will be based on your three best exam scores (possible 300 points) with some adjustment for varying exam averages. Your worst exam score or a missed exam will be dropped. Quizzes: Between examinations, four quizzes worth 25 points (total 100 points) will be given to help keep you prepared for the coming exam. Quizzes will be given in the last 15 minutes of class and will concern only some material covered since the last exam. Quizzes are scheduled for the following days: Sept. 13, Oct. 4, Oct. 30, Dec. 4 Laboratory: The schedule for laboratory experiments is listed on a separate sheet. Your attendance at your assigned laboratory section is required. If you need to miss your assigned lab section to participate in a Colgate athletic contest or another Colgate sponsored function, contact the laboratory coordinator (Dr. Julie Chanatry) well before your absence to schedule a make-up date. Excused absences from laboratory (e.g. due to illness) should be made up within one week. If you are ill and will not make your scheuled lab meeting, contact Dr. Chanatry. The dates when lab reports are due are also listed in the laboratory manual. Lab reports are due one week (seven days) after the lab, at the beginning of your next lab period. (Adjustment in the due date will be made for school holidays.) Turn in your reports on time. Late lab reports are not accepted.
As much as possible, the laboratory experiments will coordinate with the lecture material. Therefore, principles covered in the laboratory will also be covered in class. Material from the laboratory will appear on quizzes and exams. READ EACH WEEK'S LABORATORY EXPERIMENT BEFORE COMING TO LABORATORY. PREPARATION for laboratory will help you perform the experiments correctly and efficiently. Lab quizzes (given by the laboratory instructor) are possible. Required each week in laboratory: safety glasses or goggles laboratory notebook laboratory manual calculator (most weeks) proper attire (no sandals or shorts, tie back long hair or loose clothing) Your laboratory grade will be assigned by your laboratory instructor and will be based upon your laboratory reports and upon your laboratory performance. FAILURE TO SUCCESSFULLY COMPLETE THE LABORATORY WILL RESULT IN FAILING THE COURSE. Grading: Your attendance in class is expected, but not an explicit part of your grade. It has been noted, however, that students who attend class and keep up with the reading and homework problem assignments do considerably better on quizzes and exams than those who do not. Attendance at exams and quizzes and in laboratory is required, of course. Homework problems will be assigned regularly, but they will not be collected or graded. However, the answers to the problems will be available. It is a better learning experience to attempt to solve the problem before you look at the answer. Also, representative homework problems will be solved in class. Please come by my office for additional help outside of class. In the evenings, chemistry tutors are available without charge. Tutors are available on a drop-in basis and also by appointment. Your grade in Chemistry 101 will be based upon the quality of your work on quizzes, hour exams, in the laboratory, and on the final exam. The distribution of possible points is summarized below: Hour Exams: 300 points Quizzes 100 points Laboratory: 150 points Based upon your laboratory reports and your performance in the laboratory Final Exam: 150 points Common exam for all Chem 101 sections Comments: (1) There is no fixed scale or quota system for the assignment of grades in this course. Grades are based upon your ability to master the material and your demonstration of that ability on quizzes and exams and in the laboratory. Of course, higher scores result in higher grades than lower scores. (2) FAILURE TO SUCCESSFULLY COMPLETE THE LABORATORY WILL RESULT IN FAILING THE COURSE. Cheating: Honesty is absolutely essential. Cheating (successful or unsuccessful attempts) will not be tolerated.
--------------------------------------------------------------------------------------------------------------------- ------ How to do well: Year after year, it has been noted that the most successful students keep up with the material in their chemistry class. Read the assigned material in the text before the lecture and again after the lecture. Chemistry reading is not light reading. Several readings of the material may be needed to understand it. Attempt to solve problems as the concepts are introduced in the text. Try to do a bit of chemistry homework every day and stay current with the material. Do many homework problems. Be sure to make a serious attempt to solve a problem before you look up the answer. ASK QUESTIONS when you don't understand a concept, a solution to a problem, or whatever. All of the instructors have office hours and we also employ upper-level chemistry students to provide tutoring in the evenings. Take advantage of your opportunities, stay inquisitive, and you will be able to master the material.
