  2. Introduction • Why study chemistry? • Our society depends on science and technology. First class medical care, varied food supplies, transportation, rapid communication, and personal comfort are usually taken for granted. Chemistry has played an important role in these developments. • engineering materials • drugs-ex: L-dopa, a drug use for treatment of Parkinson’s • recombinant DNA lead to the bacterial synthesis of human insulin for treatment of Diabetes. • phosphorous lead to the discovery of organ pesticides which along with other pesticides reduce crop losses enough to feed an estimated 500 million more people. • Even the everyday items such as rubber bands, toothpaste, and the dye in blue jeans reflect the input of chemists.

  3. Scope • This course is a comprehensive treatment of inorganic chemistry topics. Some topics include: • Chemistry in the Community by Freeman and Company • Water:Exploring Solutions Sources and uses, Looking at water and its contaminants, Water purification and treatment • Petroleum:Making and Breaking BondsWhat is it?, An energy resource, A building material resource, Energy alternatives • Materials:Structure and UsesWhy we use what we do, Earth’s mineral resources, Conserving matter, Designing materials • Air:Chemistry and the AtmosphereGases in the atmosphere, Radiation and climate, Acids in the atmosphere, Air pollution

  4. Scope (cont.) • Chemistry is a rigorous course which requires a serious attitude on the part of the student. • Laboratory work plays a major role in classroom activities. Lab safety, study skills, and problem solving are all woven into the course. • The student is expected to spend at least 20 minutes per night on reading, written assignments, lab reports, and projects.

  5. Policies • MaterialsScientific calculator; 3-ring binder with lab section; Pencil and pen every day. You may not borrow a calculator during a test or quiz. • Textbook Chemistry in the Community • EvaluationThere is a test at the end of each chapter. There is no midterm exam. A comprehensive final exam will be given in June. • GradingTests/quizzes are 75% of your marking period grade; Labs, Projects and homework total to 25%. • HomeworkPlease plan on a minimum of 20 minutes of homework each night.

  6. Policies • Clinic I am available every clinic day unless a meeting requires my attendance. • Conduct Students are expected to treat others with respect and follow all rules outlined in the student handbook. • Important Rules Do not interfere with the safety and learning of others • Absences Find out what was missed when you were absent (call a chem. Friend) and complete it within a period equal to the length you were out. Check the “bin” for missed worksheets. If you are out during a test day, you must take the test after school on the day you return. Failure to make up work in the allotted time results in a zero. Labs must be made up within one week from absence. allowing someone to copy work, or taking a test, quiz, or exam in a dishonest way. Plagiarism is a form of cheating.Any student caught cheating on a test, quiz, midyear or final exam, term paper, book report, etc. will receive a zero for their part in that activity. • EvaluationCombination of points (see grading). Quizzes may be unannounced when necessary.Remember: What you put in to something is what you get out

  7. Element Story (Indium) the summer (Iodine) decided I wanted to dye my hair. I was going for a look with (Ag) and (Au) highlights, but it didn’t exactly turn out that way. My hair was (Pt) blonde. When my dad first saw it he yelled (Oxygen) my God! This (Pb) me to believe that (Helium) didn’t like my new look. My mom who was (Fe-ing), was more understanding. I said (Yttnum) did this happen to me? I have the ugliest hair in (Protactinium).

  8. Element Story continued…… • (Nitrogen-Oxygen)(Uranium) don’t. Everything will (Beryllium )(Oxygen), Potassium), she said as I sobbed. • (Indium) school nobody recognized me, except for my friend (Lutetium).I felt (Arsenic) if I were the new girl in school. • I think all of the picture of me with my blonde hair (Ar), but if there (Argon) any left I’m going to (Ba). Now when I think about it, though, I’m glad my hair wasn’t (Ne) green!
