Prerequisite: CHEM 108 or equivalent college level course or appropriate chemistry skill level demonstrated through Chemistry Diagnostic Test; MATH 120 or equivalent.
Recommended: eligibility for ENGL 122 or equivalent.
Note: Calculator used in this course.
An introduction to the fundamentals of chemistry including such topics as atomic theory, bonding, structure, stoichiometry, gases, solutions, redox, thermochemistry, equilibrium, and acid-base chemistry. CAN CHEM 2 CHEM 120+121 = CAN CHEM SEQ A: Course Outline

PLEASE CONSIDER CAREFULLY: The teaching style of these two Chem 120 sections incorporates many innovations in undergraduate teaching methods and technological materials, which depart from, but are built upon traditional textbook-lecture centered science courses. The organization and approach are likely quite different from other courses that you are experienced in and comfortable with. The material will not be treated linearly as simple page turning in relation to the course textbook. You will be challenged personally: to find and access a variety of information, to appraise its value, and to use it constructively to answer questions, to solve problems, and to build knowledge. You will have various assets and tools available that go well beyond the textbook and lecture notes. You will need to decide how to use them effectively, and to develop your own personal learning plan accordingly. Not all knowledge in chemistry will be provided to you to repeat back accurately for a grade as you are accustomed to in most courses. Your plan will most likely be different than anyone else's. Without a plan that you can use productively and adjust as the course progresses, you will likely not meet your personal objectives. This metacognitive approach to teaching-learning will translate to any of your other courses and more importantly empower you to effectively address any topic in any discipline at anytime in your careers.

4. Class Preparation & Homework: Practice and staying current with the course content on a daily basis are essential to your success in this course of study. The amount of preparation, practice and time required will differ for each of you. A scientific study of students at Notre Dame University has shown that final grades in general chemistry are directly related to the amount of time students invest. In order to score well on exams & quizzzes, the questions to ask yourself while going through this experience are, "Can I teach this concept to someone else? And, can I recognize and correctly answer questions that are similar to the ones contained in the in-class clicker response questions, the worksheets, the on-line/textbook problems, and the class/lab activities?". Correlating the time related to your answer to these questions will provide an estimate of what you will likely need to invest. Exams will be designed to test content & concepts based on these materials. There will be periodic chapter/topic quizzes that will also be based on these materials. Recommended order of emphasis is:  1) Read the on-line Class Slides & Clicker Questions linked from the calendar before coming to each class 2) Collaboratively complete all worksheets in a group with 1-3 partners 3) Individually complete all on-line Webassign questions, 4) as time allows and your proficiency may require do as many end of chapter textbook problems as possible; refer to the course assignments page and calendar page.

5. Grading:
Attendance and Homework are valued at 10% of the TOTAL grade. The class portion of the grade is worth 65% of the total grade. It will be comprised of quizzes and worksheets, (which in total equal one exam), 3 in-class exams, and a final exam, which is equal to two hour exams. Tentative Exam Dates: 9/21, 10/28, 12/7, 12/14 (FINAL). A laboratory grade worth 25% will account for the remainder of the total grade. Final letter grades will be assigned based on: 90-100 A; 80-89 B; 65-79 C; 50-64 D;<50 F, using a normalized class average. NOTE: The DVC Code of Conduct will be strictly enforced. Cheating and plagiarism are unacceptable and will unconditionally result in a failing grade. [Cell phones will not be allowed in rooms during exams and quizzes.] SEE: DVC Academic College Policies

6. Attendance / Tardiness / Absences:
On-time attendance at all scheduled class and lab meetings is unconditionally expected. It and homework are valued at 10% of the TOTAL grade. If you arrive late for class or lab, you will be marked absent. Two late arrivals will be excused provided that you see Dr. R. immediately after class or lab. If you are to miss a class, quiz, exam or lab due to illness or other legitimate reason, you must advise Dr. R. prior to, or on the day that it is scheduled. If you do not do so, there will be no possibility of making up any missed work or of being excused from assignments, activities or the material presented. Notifying Dr. R. can be done by calling: 685-1230, ext. 2508 or leaving a message with the department secretary (ext. 2423) or sending an e-mail to Dr. R. If you miss a cumulative total of 8 laboratories and/or lectures regardless of the reasons, you may be dropped from the course. [College policy provides for a student being dropped from a course if the student misses a cumulative total of two weeks of class/lab meetings.]

7.  Laboratory:
The laboratory component of the course is essential to the overall course. A failling grade in the lab portion will result in a failing grade for the course.

There will be experiments and activities that will be done on a group or team basis as well as indivdually. For each experiment, you are to prepare a pre-lab report prior to beginning a lab and a finished report on completion of the lab unless Dr. R. advises otherwise. You will be advised of the specific details for each lab.

Pre-Lab reports must be prepared prior to each scheduled lab. They must be in the following format, and include: Title, Purpose, Procedure, Chemical Reactions (where appropriate) and neatly organized, labeled, blank Data  Tables with the units of measurement, eg. grams, mL, etc. and any assigned questions. Before you begin any lab, you must have Dr. R. initial the lab notebook page with the pre-lab report. If you miss a lab for any reason, Dr. R. must be advised the day of the lab or there will be no possibility of making up the lab.

The finished, complete Lab report must be in the following format, and must include all pertinent information including unknown numbers where unknowns are part of the experiment. Finished copies of the report will be collected. Lab Reports must be neat and legible. Significant deductions will be made for failure to follow any of these guidelines.

Title

Purpose:
A brief statement of the experiment's objective: Answer the question...what is your aim?

Procedure:
Include what you actually did so that someone else could repeat your work. The directions can be an outline of the actual conduct of the experiment in your own words. This section should be written in the past tense. Refer to the Lab instructions but do not copy them word for word.

Chemical Reaction(s):
In experiments with chemical reactions include, Complete, Balanced Chemical Equation(s); as many as appropriate.

Data:
All physical-chemical data used in the experiment (molecular weights, density, etc.) Should be provided in neat, well organized Tables of labeled experimental data with correct units and appropriate number of significant figures. If tables are provided in the Lab text, they can be appended. Raw data & observations should be included in this section.

Calculations:
Show how the numerical data was handled (i.e. the general mathematics): algorithms (formulas and equations), unit factor method, etc.and include one example. Do not include calculations for all trials, but do show average(s) and average deviation(s) for multi-trial experiments as required. Be as neat and concise as possible.

Results and Conclusions:
Re-state in one or two short sentences the results and your conclusions versus the intended purpose of the experiment. Use tables if appropriate.

Questions:
Answer any pre-lab and/or post-lab assigned questions.

___________________________________________________________________________________________________________________________

Safety:

Laboratory safety is of the utmost importance to your well being and to your lab mates. Chemical exposure must be minimized through good lab practices. All wastes must be properly disposed of. Eye protection must be worn at all times. No one can work in the lab without an instructor being present. Only scheduled experiments are allowed. Bare feet, food, drink, eating, and conduct which places anyone at risk are unacceptable. Violation of safety standards can result in being dropped from the course.

Internet use and related:

The course will employ the Internet and Information Technologies in a variety of ways. This is NOT a course which teaches the Internet. The course is designed to use the Internet with its wealth of resources as a transparent tool to teach chemistry. Combined with good study practices, it will help you, the student, to better and more easily understand concepts and to make your learning experience broader and more successful.

Students are not required to have a computer or off campus access to a computer.

Free e-mail accounts are available. Each student MUST have their own e-mail account for class communication.

There will be no charges for the use of the Internet, computers or course related software.

The course will employ the Internet and Information Technologies in a variety of ways. The class will need the latest version of a Net browser for the Internet as well as other computer programs. All of these programs will be free for student use. (See Web Materials for a listing.) Since it is realized that not every student has a computer or off-campus access to a computer, computer related assignments are devised and time budgeted so that these assignments can be done while on the DVC campus by accessing the Internet from the Physical Science building's computers or other computers on the DVC campus that are available to DVC students.

Students are expected to visit the course Homepage regularly. The Homepage is the main tool for communicating information to the class. It includes all information on the course in addition to providing Internet links to many useful Web sites and materials for the course. The Homepage is a living course document. Information will be added as the course proceeds and past information will be archived.

If you do not already have e-mail, consult the Web Resource information linked from the Homepage for information on how to obtain your free e-mail account. Select a provider: Yahoo, Hotmail, G-mail, etc. and follow their on-line instructions.
