AP Summer Institute – Course Description

Western Kentucky University

June 24 – June 28, 2013

This APSI will introduce the redesigned AP Chemistry curriculum framework, with particular emphasis on Big Idea 4 (Chemical Thermodynamics), Big Idea 5 (), and Big Idea 6 (). 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 • Oxidation/Reduction and Electrochemistry, Work in Chemical Reactions • Chemical Kinetics and the Rates of Chemical Reactions • Chemical Equilibrium

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.
