Chemistry II

AP Summer Institute – Chemistry Course Description

University of Louisville

June 16 – June 20, 2014

This APSI is designed for teachers new to the AP Chemistry course (Less than 3 years experience).  The course will outline major topics in the redesigned AP Chemistry curriculum framework, with particular emphasis on Big Idea 6 (Chemical Equilibrium) and the foundational concepts of Big Ideas 4 (Chemical Thermodynamics) and 5 (Chemical Kinetics).  Participants will engage in extensive guided inquiry laboratory work and will develop or refine a laboratory program appropriate to the redesigned AP Chemistry course.

Additional, participants will be guided in syllabus development and will begin the process of preparing the course audit, as required by the College Board.

Topics will include the following:

  • An introduction to the redesigned AP Chemistry Syllabus
  • Prior knowledge and Pre-AP Chemistry
  • Resources for AP Chemistry
  • Thermochemistry, Energy and Enthalpy in chemical and physical changes
  • Thermodynamics, Entropy, Free Energy, and Spontaneity
  • Chemical Kinetics and the Rates of Chemical Reactions
  • Chemical Equilibrium
  • Relation to Thermodynamics and Kinetics
  • General and gas phase equilibrium
  • Heterogeneous equilibrium
  • Aqueous equilibrium
  • Solubility equilibrium and Ksp
  • Acids, Bases, and Buffers

What participants should bring:

  • AP Chemistry Textbook
  • Scientific calculator and lab safety glasses.  Participants should be prepared with laboratory appropriate clothing (i.e. closed toe shoes).
  • Notes and laboratory exercises are provided for participants

 

In addition, participants will find it convenient to bring a laptop computer or iPad equipped with a spreadsheet utility and capable of accessing on-line resources.

Consultant

After teaching AP Chemistry, Physics, and Calculus at independent schools in North Carolina, California, and Kentucky, Lew Acampora is currently the living in Louisville and acts as the statewide (KY) Science Content Director for the National Math and Science Initiative.  Mr. Acampora has been involved in the AP Chemistry reading for 18 years, first as a reader, table leader, and most recently as a question leader.  He has written questions for the AP Chemistry test, and has served on the PRAXIS test development committee.  Mr. Acampora graduated with a B.A. in chemistry from Harvard University, and has done graduate work in chemistry at Brandeis University and the University of North Carolina at Charlotte.
