Evaluation and Grading

Homework (9 assignments)15%

Labs (8 experiments), Lab notebook (graded twice)25%

Quizzes (9 quizzes, lowest score dropped)30%

Final Exam20%

Participation10%

To estimate your course grade mid-quarter calculate the following:

0.15(%Homework) + 0.25(%Lab) + 0.50(%Quiz) + 0.10(%Participation) = Current %Grade

Your final grade will depend on this percentage: 95% = 4.0; 90-94% = 3.5-3.9; 87-89% = 3.2-3.4; 84-86% = 2.9-3.1; 80-83% = 2.5-2.8; 77-79% = 2.2-2.4; 74-76% = 1.9-2.1; 70-73% = 1.5-1.8; 66-69% = 1.1-1.4; 60-65% = 1.0; <60% = 0.0.

Homework

Working through problems is the best way to understand chemistry. There will be one homework assignment due per week, generally at the end of class on Thursday. Assigned problems will be from the text, check website regularly for updated problem lists. Note that answers to selected problems are in the back of the book. For full credit, show all work needed to derive the answers, and offer explanations as necessary. Selected problems may be checked for correctness, however most of the points will be awarded based on completeness and timeliness. Answer keys will be available online after the homework is collected; it is your responsibility to check your answers against the key. Ask questions when your answers differ! The more problems you do, the more likely you are to succeed in this course; working additional problems beyond those assigned is highly recommended.

Labs

Come to lab prepared! Read the experiment, prepare the lab notebook, and complete the pre-lab assignment in advance of your lab period. Pre-lab assignments are due at the beginning of the lab period, lab notebooks will be initialed by the instructor shortly after experimentation begins. Record data and observations in your lab notebook as you proceed with the experiment, copying final numbers and other requested information into the report sheets (available in the lab manual) once you are done. Report sheets must be initialed by the instructor prior to leaving the lab to receive full credit. Lab reports, the combination of the report sheet along with answers to the post-lab questions, will be due at the beginning of the next lab period. No make-up labs will be allowed. The last day to check out of lab is December 10. Penalty if not checked out by then is 25% off the final exam.

Quizzes

Nine 25-30 minute quizzes will be given over the course of the quarter; one quiz each Friday. Your lowest quiz score will be dropped. Bring your calculator; no other materials or notes will be permitted. A copy of the periodic table will be provided as needed. Any student caught cheating will receive no credit for that quiz. If you can’t make a quiz as scheduled, you must contact me before the quiz takes place if you would like to arrange a make-up. Make-ups will only be considered if documented reasons for the absence are presented, otherwise this will be the quiz you drop.

Final Exam

The final exam is cumulative, covering concepts from the entire quarter. In order to pass this course, you must take the final exam. The final exam will take place on Monday, December 8, 10:30am.

Participation

Your participation score is based on attendance and effort displayed during the class. Participation in group exercises is expected. About once a week worksheets (available in class and online) will be distributed; these are to be worked on in groups of two or more students, and one completed worksheet per group (don’t forget anyone’s name!) will be turned in for participation credit after we discuss the problems in class.

5.PHYSICAL CHANGES AND CHEMICAL REACTIONS

  • Recognize and describe changes in heat and temperature associated with physical and chemical changes.
  • Classify and balance chemical equations and predict products for different types of reactions.

Course accommodation: If you have any special circumstances requiring course accommodation, please see me as soon as possible so that we can make suitable arrangements in advance. In this course(as in all courses at Seattle Central) all students will be granted an equal opportunity to learn and succeed, regardless of race, class, gender, religion, ethnic origin, nationality, sexual orientation or physical disability. If you have any concerns pertaining to these issues, please feel free to speak to the instructor or department dean.

Students with documented disabilities requesting class accommodations, requiring special arrangements in case of building evacuation, or have emergency medical information the instructor should know about are asked to contact the disability support services office (DSS) in Rm. 1112. Once the disability is verified with DSS you will be given a letter of accommodation to be handed to your instructor.

Laboratory Notebook

Whether you work in a health-related profession or in a lab setting, it is of the utmost importance to learn how to keep accurate records of any procedure performed. In Chemistry 121 we shall start to introduce you to this by requiring that you keep a lab notebook.

In all laboratories, data taken in the lab is written down (in pen) in a lab notebook with numbered pages. All entries must be kept current and entered as the work is performed. Strict guidelines have been developed for those working in all types of lab settings: Biotechnology, chemical, analytical chemistry, environmental labs, etc. The purpose of this strict record keeping is to insure that anyone can duplicate your work, if necessary. If patents have to be applied for, the date and time of your original work can be documented and proven in court and you can take your work and produce professional reports for submission to your boss or other authorities. The lab notebook will be collected and graded twice—once just after the Cations and Anions lab and again at the end of the quarter.

Guidelines for record keeping:

1. Purchase from the bookstore a hardbound notebook (composition book). Pages should be numbered (by hand is acceptable).

2. On the outside, write your name and course number clearly so you can identify your book easily.

3. On the inside cover, draw a diagram of the lab highlighting the safety equipment. This drawing must be shown to the instructor on the second lab day.

4. Use the first right-side page to construct a Table of Contents and keep this current with titles of experiments and page numbers. As you come to lab each week your instructor will initial your new entry after checking that your lab notebook preparation is complete.

5. Pre-Lab notebook preparation—prior to the start of each lab period write out the following in your lab notebook for the experiment you will be conducting:

  • Title of the experiment
  • A short purpose (what you intend to accomplish with this experiment).
  • A brief summary of the procedure you will use; about one page will suffice. Do not copy the procedure verbatim from the packet!
  • Data Tables similar to the report sheets included in your lab manual.

Note: Use the right-hand pages for records and data; leave the left-hand pages empty or use them for scratch paper, preliminary observations, notes and calculations. All notebook entries are to be done in pen only.

6. When you come to lab the instructor will collect your pre-lab assignments (available in the lab manual, to be completed separate from the lab notebook and turned in) and check your pre-lab preparation. During the short talk preceding each lab, make notes on changes in the procedure or other pertinent information in your lab notebook. This is an important part of the record.

7. As you perform the experiment, record all data in ink in the notebook. Include descriptions and observations. The notebook should be a diary of your work with sufficient information such that an outsider can repeat the experiment and reproduce the results following your procedure.

8. Once you have finished the experiment, copy final numbers and other requested information from your lab notebook into the report sheets available in the lab manual. Report sheets must be initialed by the instructor prior to leaving the lab.

9. Before the next lab period, answer all post-lab questions outside of the lab notebook; these questions in combination with the report sheet constitute your Lab report which is due at the beginning of the next lab period.
