  1. New York State Science Olympiad Coaches’ Meeting 28 October 2011 Chemistry Lab Event • Overview and Introduction • Regional Competition • State Competition • Feed back from previous chem lab competitions • We don’t want to make the same mistake …. For questions, contact: Mr. Jim Williams Ms. Jen Wagner 914-721-2596 914-721-3385 jwilliams@scarsdaleschools.org jwagner@scarsdaleschools.org

  2. Chemistry Lab • Introduction • Periodicity • Trends • Predictions • Organization • Electrochemistry • Galvanic and electrolytic cells • Energy applications • Favored and non-favored reactions

  3. Chemistry Lab • Regional Competition • Practical Lab Skills • Make predictions based upon periodic trends • Generate activity series • Examination • Vocabulary • Calculations • Analysis

  4. Chemistry Lab • State Competition • Practical Lab Skills • Use predictions based upon periodicity to solve problems • Develop standard reduction table • Examination • Vocabulary • Calculations • Analysis • Use electrochemistry to determine reaction rates

  5. Scarsdale High School Useful Resources • Interactive Periodic Tables • http://www.learner.org/interactives/periodic/basics.html • http://www.ptable.com/ • http://periodictable.com/ • http://www.chemicalelements.com/ • Redox • http://sciencespot.net/Pages/classchem.html • http://www.sasked.gov.sk.ca/branches/elearning/tsl/resources/subject_area/science/chem_30_resources/lesson_12/default.shtml

  6. Chemistry Lab • Feedback and Questions Jim Williams: jwilliams@scarsdaleschools.org Jen Wagner: jwagner@scarsdaleschools.org Web Site: http://scarsdale.schoolwires.net/shs/site/default.asp Select the “Teacher Pages”. Select “Williams, James”

  7. Sherman notes: • Be sure to know the listed ions on the rule sheet • on the state test know the history • state test MAY be electrolytic cell or Nernst equation if they cannot get electrolysis equipment • Fuel cells definitely on state test • Definitely be balancing an acid at states • Points for cleaning up – be sure to stop at a good time so you don’t lose points • No reference tables given – may get a periodic table • Know how to calculate the mean from data, standard deviation • Don’t forget goggles (tight on face), aprons

  8. Sherman notes continued: • Given a fixed amount of chemicals – use wisely – no extra chemicals given • He tends to stay away from spontaneous and nonspontaneous • Stoic on state test • Full explanation for trends may be a tie breaker on states
