Homework Schedule

 

Homework assignments are on a weekly basis to help you learn the course material according to the performance objectives and to help you to test your mastery of the material considered. They are not to be considered "exclusive" but representative of the material. If you feel the need to do additional reading or problems, you can ask your instructor for guidance. All but the last column will be found in Whitten, Davis, Peck, and Stanley

 

The only way to learn the material is to do it yourself. Chemistry is a problem solving course. You can only master it with practice.

General Chemistry I is intended to provide you with an initial exposure to a broad realm of fundamental concepts in chemistry. It will assist you in attaining a basic understanding of these concepts, and it will help you to develop essential skills in these areas. The lectures, recitation discussions, laboratory sessions, homework assignments, quizzes, and examinations provide an integrated selection of activities which can lead you to success, provided that you are conscientious. In order to re-ceive credit for the course, you must at least meet the minimum requirements de-scribed below. Additional effort and achievement will be especially rewarding however.

         For those who study chemistry, the benefits to be expected are an increased capacity for

         enjoyment , a livelier interest in the world in which we live, and a more intelligent attitude

         toward the great questions of the day.

        Participation in Chemistry laboratory courses is permitted provided the student has completed

        the required prerequisites, is a minimum of 16 years of age, or by permission of the instructor

        and the Dean of the division.

 

 

        It is the college policy that a student taking the class as an Audit must declare this  at the

        time of registration, and may not attend the laboratory, may not take exams, and may not

        have quizzes graded.

 

 

        If you need an accommodation, you must bring the form at least 2 weeks before it will be used.

  Students behavior deemed unsafe by the laboratory instructor will be grounds for removing a student from the course with a grade of WI or F.

 

Performance Objectives:

.

 1.     You must satisfactorily complete on an individual basis the assigned laboratory experiments.  (Missing 3 or more will constitute an F or W for the course)

 

 2.     You must participate in weekly recitations (missing 3 or more may constitute an F or W for

         the course)

 

 3.     You must complete the weekly quizzes and hour tests, as assigned, showing work, thought process and/or justification for answers when necessary.

 

 4.     You must complete all of the assigned homework

 

 5.     You must achieve a passing grade on a comprehensive final examination.

 

 6.     You must complete a minimum of 6 hours of work (not counting lab write-ups) on chemistry

         at home each week.

 

 7.     You must demonstrate your level of performance (see page 3 for "grading") by mastering a

         large part of the material covered by lectures, videos, homework, laboratory work and the textbooks as detailed in the specific course objectives that follow.

 

8.      Since you will need a C or better in CHE 101 to take CHE 102, it is expected that

         you have a working knowledge of CHE 101 and can expect test questions on this material or

         that depend on knowing it in CHE 102.
