Enrichment Topics (time permitting) Carbon and its’ compounds and an introduction to polymers and current commercial products and their chemical nature, nuclear chemistry, environmental chemistry, biochemistry. Textbooks supplemented with current periodicals. Note: Content of syllabus may be subject to change. CLASSWORK: Read assigned text material ahead of the class in which it will be discussed. Get your questions answered as soon as possible. Participate in class by asking your questions, offering answers to your classmates including observations, experiences you have had, or current science events into our discussions. Daily drill to be completed and reviewed during the beginning of most classes. HOMEWORK: Homework is an expeditious way to practice your proficiency with various concepts in chemistry. Homework will be assigned as a block at the start of a chapter and is due no later than the day of the chapter test. Students are encouraged to complete reading and homework assignments daily. Homework should be submitted on white paper with straight edges and be neat, and easy to read. All work for problems and calculations must be shown. There will be a 5-point deduction for late homework. (This usually correlates to a letter grade decrease.) EXTRA CREDIT: Extra credit is assigned during each quarter and usually varies between 20- 35 points. It is optional. There is no extra credit beyond what is assigned and no make-up is permitted once the due date is passed. LABS: Before each lab I will explain the lab to you. Preparation for the lab is essential. You must carefully read each lab before the scheduled lab time and complete any pre-lab work required before the scheduled lab time. Labs will take one class period only; therefore you must be ready to work when you enter the lab. Incomplete labs will lose points! Normally, one lab will be performed for each chapter covered. Lab assignments are due the second class after the lab; they must be neatly typed or written and easy to read, with all data and calculations shown. (Refer to format). There will be a 10-point deduction for late labs. Labs missed due to an excused absence must be made up immediately when the student returns to school. LAB SAFETY: Safety in the chemistry lab is critical. Students will follow proper lab procedures and wear personal protective equipment at all times while conducting experiments. Any student disregarding safety rules or engaged in horseplay will be removed from the lab and receive a grade of “0” for the particular lab. TESTS: Tests will be given at the end of each chapter. If you are absent on the day of a test, you must make it up within 1-3 days after you return to class depending upon the length of your absence. It is your responsibility to arrange for the make up of a test. Tests are not curved. Please read the student handbook for course attendance policies. NOTEBOOKS: Students are required to maintain a notebook (three ring binder either separately or shared with another subject) for the purpose of organizing work, providing a record of progress, and as a source of information. The notebook may be maintained in chronological order or it may contain separate indexes for the course syllabus, class notes, homework, and returned tests and quizzes. The student may decide which format is best for him/her. Save all work in the event that a grade or assignment is in question. EXTRA HELP: Extra help is available upon request and you may make arrangements for this with me as necessary. If you come in for help, be prepared to ask specific questions. I am here early and after school every day. GRADES: Grading will calculated on a percentage system. Tests/Quizzes 50% Homework 35% Labs 15% NOTICE: If you do not do your homework, it will be impossible to pass this course! GRADING SCALE: A……..93-100 A-...90-92 B+…….87-89 B…..…83-86 B-...80-82 C+…….77-79 C……..73-76 C-...70-72 D……..65-69 F……..64-below Grading: Grades are calculated as total points earned divided by total points available. If you are within one half point of the next highest grade, I look at extra credit completed, quality and timeliness of completed lab reports and homework, class conduct, and class participation to determine if the higher grade is deserved. There is no automatic rounding up regardless of how close you are to the next highest grade! Academic Honesty: Although students are allowed to work together, they are not allowed to copy homework, copy lab data, information, or calculations from other groups, program formulae, vocabulary, etc. into calculators, give or receive testing information, or submit any work that is not their own. LABORATORY GUIDELINES 2008 - 2009 Chemistry 432 Attire 1.During all experiments, students are required to wear safety glasses; aprons are also required. 2.Only school approved shoes may be worn; refer to Dress Code Policy. 3.Long hair will be tied back for experiments. General Safety 1.Students are NEVER to work alone. No working without direct teacher supervision. No unauthorized experiments are allowed. 2.No eating, drinking, or chewing gum while working in the lab as you may inadvertently ingest some chemical substance. 3.Lab is not a social hour. Students will work quietly and must remain at their lab stations unless obtaining supplies. Students may not “visit” with other groups. Excessive noise in the laboratory is viewed as a safety hazard. 4.Students must know where the eyewash, fire extinguisher, and fire blanket are and how to use them. 5.Any accident of any kind must be immediately reported to the teacher. 6.Never heat a “closed system” such as a stoppered flask. 7.Never leave a lit Bunsen burner unattended. 8.Dispose of broken glass in the specially marked waste receptacle. 9.Keep your work area clean, and help keep the common areas of the laboratory clean. If you spill something, clean it up right away to avoid a slip hazard. 10.As always, students will conduct themselves in a decorous manner. No one has the right to jeopardize the safety and well being of others. Chemical Handling 1.Consider all chemicals to be hazardous and read all labels carefully. 2.Never touch or taste chemicals. 3.Never directly inhale chemical fumes. Waft a tiny amount of vapor toward your nose. 4.Do not return excess chemicals to their original container. Always use the smallest amount of substance required for an experiment. 5.Solids are not discarded in laboratory sinks. 6.Never add water to a concentrated reagent when diluting the reagent. Always add the reagent to the water. If water is added to a concentrated reagent, local heating and density effects may cause the solution to be splashed back. 7.When in doubt, ASK. LABORATORY EXPERIMENTS Laboratory experiments will be conducted as a team project; four students per team with shared responsibilities that will be rotated with each laboratory experiment. Everyone must participate, not just observe. Duties of team members include those listed below. Each team has the flexibility to assign as they wish provided the work is shared equally and everyone participates in each lab. 1.Setup-this student is responsible for obtaining and setting up the necessary materials and equipment to conduct the experiment. 2.Experimenter-this student will conduct the experiment and generate data and observations. 3.Scribe-this student will record all observations and data, and generate one report for the group to be submitted for the team grade. 4.Cleanup-this student is responsible for dismantling equipment, cleaning all glassware and other equipment as needed, proper disposal, and return of all materials and equipment to their proper location. Any station not properly cleaned up will result in a full grade reduction of the lab report after it is graded on its merit (i.e. A®B). All lab experiments will be assigned a day or two in advance if possible. Students must have read the laboratory experiment prior to the lab and be fully prepared to conduct the experiment including having calculated formula weights of chemicals, construct tables for data entries and observations if required, etc. Each student is responsible for recording all data and observations in their laboratory manual as well as answering all questions. The notebook and final report should record both successful and unsuccessful experiments. If you make a mistake, record what happened so that you will not repeat the same mistake. All calculations you have performed before, during, or after an experiment should be entered, both to help you understand your results and help me find errors you may have made. Team Report Each team is to submit one report for each laboratory experiment for a group grade. The format for the report is as follows: 1. Title of the laboratory experiment and date. (Cover page) 2. Names (first and last in alphabetical order) and responsibilities of partners along with your P– day schedule number. (Cover page) 3. A Statement of Purpose or Objective of the experiment with all pre- laboratory data and calculations if required. 4. Description of the experimental procedure. Do not just copy the description from the lab manual. Instead, understand the basics of the procedure used and summarize this in a few sentences. Use diagrams to reduce lengthy descriptions. Observations written in the manual should be complete enough so that anyone with your level of scientific training could understand what you have observed and measured. 5. Results. This is where all of your data and calculations appear along with the calculation of experimental error based upon deviations from the standard or accepted values. All your original data must be included in data tables and all calculations must be shown along with the corresponding units. 6. Discussion of Results includes answering all of the questions in the manual in complete sentences; i.e. what went wrong and what went right, what could have been done differently to improve results, comparison of your results to accepted values (additional research may be required), calculating percent error, and general observations/theories that can be drawn from your results. Note: Number your question responses as they appear in the lab manual. Do not answer questions in paragraph form. It is not necessary to copy each question; however, include the question in your answer. 7. Conclusions include a concise summary of how successful you were in accomplishing the objectives of your experiment, what could have been done differently etc. Evidence should support your conclusions. I consider these team reports to be technical papers. As such, they must be written neatly and legibly or typed and complete using proper formatting and fonts (superscripts and subscripts for exponents and chemical equations). Use Times New Roman with 12 point font and 1” margins. Major deductions will be given for sloppy or incomplete work. You may use hand or electronically generated sketches to aid in descriptions. Each member of the team will receive the same grade assuming equal contribution. Each report will be graded on content as well as presentation which includes correctly following the format, neatness, proper use of grammar, ease of understanding, inclusion of all original data (in data tables), showing all formulas and calculations, answering all assigned questions etc. Lab due date: The lab report is due on the date assigned at the start of class. If a class drops on that day, the report must be submitted to me before the end of the day. There will be a 10-point deduction for late labs unless prior arrangements are made. Extensions are rarely given. Note: Team members are responsible for reviewing the report prior to submittal to ensure it properly reflects the agreed upon content, but all members are to turn in their own copies and anwer the questions in his/her own words. Any student who does not contribute fairly to the completion of the lab will receive a grade of “0” and may or may not receive an alternate assignment at my discretion. Any lab missed due to a legitimate absence must be made up immediately upon the student's return to school. Late Work: 1. Homework is due at the start of class on the day of the test. Late homework is a minimum 5-point deduction. 2. Lab reports are due at the start of class on the day assigned. If a class drops on the assigned day, students have until the end of the assigned day (3:00 pm) to turn in the report. There is a minimum 10-point deduction for late labs. 3. Extra credit is due on the day assigned and must be complete. There is no partial credit and no make-up is permitted once the due date is passed. Note: There are no exceptions unless prior arrangements have been made with me.
