4. Course Description

A. CHEM 135 is a laboratory course designed to give the successful student an introduction to chemical methods of analysis including volumetric, gravimetric and spectrophotometric methods of analysis. Accuracy and precision is emphasized through applications of basic statistic. Successful completion of this course will give the student the necessary laboratory skills to succeed in their field of study. This course is designed for the student majoring in science, engineering, or pre-professional programs. This course satisfies the general education requirement for science.

B. College Wide Abilities- The College Wide Ability groups are attributes that college faculty want our graduates to develop while at Clark College. They include: Information Technology, Communication, Life-Long Learning, Effective Citizenship, Critical Thinking, and Global/Multicultural. After assessing the course material, I will focus on developing skills for Critical Thinking/Problem Solving CHEM 135 in the context of material in chemistry. There will be some emphasis on developing the skills necessary for Life-Long learning.

Definition of critical thinking: The disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information. This information is gathered from or generated by, observation, experience, reflection, reasoning and/or communication. You will be collecting data and performing laboratory techniques and drawing conclusions from the data.

Life-Long learning in this course relates to making decisions on your own regarding your own performance in the laboratory. Also it is important to follow written and verbal directions, and maintain a well-organized record of your work.

5. Student Learning Objectives for Chem 135 [return to top of page]

1. Apply basic statistics in evaluation of data. (Critical Thinking Ability)

2. Learn quantitative techniques and calculations for the following laboratory processes

Use of analytical balances

Standardization and use of volumetric glassware

Titrations

Spectrophotometric analysis

Gravimetric analysis

3. Build confidence in one's own ability to make decisions regarding laboratory processes, including time management.(Life-Long Learning)

4. Review and apply in a laboratory setting concepts learned in the general chemistry sequence.

1. Sort information in order to solve typical chemistry problems using the methods of chemistry. (Critical Thinking Ability)

6. Course Policies: Each student is expected to observe the rules and regulations of the college. [return to top of page]

A. Absences

1. Attendance-Attendance and punctuality are essential for success in this class as well as being a Lifelong Learning skill. Each student is expected to attend introductions and laboratories as scheduled. Periodically quizzes may be given for bonus points. They may not be made-up.

NOTE: Instructors may drop a registered student from a class if the student fails to attend one or more sessions during the first week of the quarter (unless prior arrangements have been made). This "No-Show" policy is one of several procedures Clark College is using to stay within a state-mandated enrollment band while meeting the needs of a maximum number of students.

B. Class Participation

It is important to maintain an optimum and safe learning environment by showing unconditional respect for others. This is accomplished by listening to each other (not talking when someone else is speaking), being attentive, taking one another seriously, and allowing humor to be a part of the class. Entering into class discussions and asking questions is important, but equally important is to not monopolize class time. If you need more time to discuss an issue, use the conferences and instructor office hours.

You must be motivated, and responsible for your own results and be organized. You are expected to spend at least 4 hours a week outside of class, studying and preparing for exams and doing prelabs.

C. Course Withdrawal

1. If you should find yourself in the position where a withdrawal from the class is necessary, the college withdrawal policies will be in effect. (see the Clark College Catalog or Schedule).

2. Audits will not normally be approved unless a student is receiving a C or better in the course work up to request time.

D. Academic Honesty

Academic honesty is required at all times. Anyone caught cheating or supporting cheating will receive an automatic fail for that assignment and be subject to the Student Conduct Procedures. Copyright laws, plagiarism rules shall be observed.

7. Requirements, Assessment, and Grading [return to top of page]

1. Grading Policy
2. Grades will be based on lab reports, prelabs, lab exams, and lab notebooks. Any makeup tests will be of greater difficulty and will be given only for excused absences. Instructor reserves the right to make small adjustments in the grading scale in cases of demonstrated student improvement.
   1. Grading Scale - Most assignments and the course grade will be based on the following scale with + and – grades the lowest and highest 2% in the range:
   2. 90-100 = A; 80 - 89 = B; 70 - 79 = C; 60 - 69 = D; Below 60 = F
   3. Course Grade - The course grade will be weighted as follows:
   4. 55.% lab reports and prelabs; 35.% exams and lab practicals; 10.% lab notebooks;
3. Lab Reports

Lab reports are based on 100 points. Twenty points per class day are taken off for all late labs. Twenty points are deducted for significant figure errors. Twenty points are deducted for calculation errors. The score is based on the individual's number of standard deviation units away from the accepted value or the mean (depending on the experiment).

Prelabs are due at the beginning of the lab, the day your are scheduled to begin the experiment. 10 pts will be deducted from that experiment if the prelab is not 80% complete at that time.

C. Laboratory Exams

Laboratory exams will consist of a written exam and/or a practical exam.

A written exam will consist of questions covering the concepts and calculations encountered in the experiments and study questions. Be sure to go over all of the study questions before the exam.

Any practical portion of the exam will be a laboratory exercise graded according to three parameters: accuracy, precision and speed. The scoring for these parameters will vary depending upon the type of analysis.

d. Laboratory Safety Regulations. See the Laboratory Handbook for more information.

Eye protection must be worn at all times in the laboratory. This regulation will be strictly enforced. No goggles, no lab!

No shorts, sandals or skimpy tops in the laboratory.

No eating or drinking in the laboratory.

E. Study Each Experiment Before Going Into The Laboratory

Study each experiment thoroughly before attempting to do it in the laboratory. You need not memorize details of the procedure, such as volumes and concentrations of reagents used, but you should know the object of the experiment and the general method you will use to attain it. Laboratory time is at a premium. An error, a careless mistake, a clumsy move can cost you several hours of work that must be done over. If you come into the laboratory "cold" you will spend much valuable time making these calculations.

F. Lab Notebook- See the Laboratory Handbook for more information. [return to top of page]

1. Use the first page at the beginning of the notebook for a table of contents.
2. Information for each experiment.....

   Number each page

   Title and date on each page

   Write a brief procedure at the beginning of each experiment. You will need to read it ahead of time.

   Show all raw data, labeled and with units and appropriate sig. figs.

   Show all calculations

   At the end of the experiment, do a summary of your results- at table may work.

   Make any notes or observations you think may assist you later in lab practicals.

3. Data obtained in any scientific experiment must be recorded directly, in ink, into a sewn-bound, serially numbered notebook. All calculations and unknown information must be included. You may use the notebook to keep notes and equations on each experiment.
4. All data must be entered into the notebook as it is obtained. DO NOT RECORD DATA IN ANY OTHER NOTEBOOK OR ON ANY LOOSE PIECES OF PAPER. Such actions will result in lost points for the notebook score!
5. Show calculations and all constants used.
6. Label all data precisely so that another person, (the laboratory instructors mother, for example), who is not familiar with your organization and idiosyncrasies can tell what you have done).
7. Keep data chronologically; you may skip pages to leave room for additional data provided you eventually void all pages which are not used.
8. Errors will undoubtedly occur. When they are detected, cross out the erroneous data with only one line as you may want to read it later. Refer to the page in your notebook where the correct results can be found.
9. Never remove a page from the notebook!
10. You must have your notebook to enter the lab! It might be best to leave it locked in your laboratory drawer. Your notebook will be graded during the laboratory. Occasionally you may be asked to turn in your laboratory notebook for grading, usually at the end of the week The notebook must be handed in at the end of the term for a final grading.

Summer 2004 rt

Important Notes to students (and other faculty):

Following directions is an important Life-long learning skill.

1. You may be required to input data into spread sheets for some experiments on a selected computer. Please be careful with data entry because it has an impact on your grade.
2. Do not forget to record any unknown identification in your lab notebook as well as any report sheets.
   
3. It is recommended that you try and use your time efficiently in the laboratory. Read and try and understand all experiments before you come into the lab. It saves time in the long run.
   
4. Each experiment will be done individually, there are no lab partners except to assist in operating equipment or when described by the experiment. Each person will be assigned their own unknowns.
   
5. Grading of each experiment cannot be done until EVERYONE'S results are turned in. Be courteous and finish on time (20 pt penalty for late labs).
   
6. Please clean up after yourselves and return glassware and reagents to the appropriate location. Your drawers and equipment are your responsibility and only one other person shares the glassware.
   
7. Study questions and prelabs are in your lab packet for exams. Additional problems from your textbook may be assigned for study also.
   
8. Prelabs are required on many experiments and they are worth 10 pts each. Please get them stamped by the lab instructor before you start an experiment. They will tell you if the answer is correct or not, but will not necessarily give you a lot of help on solving the problem or looking up the answer. It is your responsibility to study the experiment handout and/or review topics in the text chapters.
   
9. Notebooks are critical. Keep yours in your lab drawer and write only in the notebook. 5 pts will be deducted from your score each time you are caught using scratch paper. All lab instructors are authorized to take your name.
   
10. Turn in only the report sheet(s) and prelab (and other requested data or graphs) for each experiment. Staple the prelab to the back of the report sheet.
