AP notes for Unit 01 have been updated with the word ‘left’ replacing with the word ‘right’, on page 34!

Subscriber Updates (09-09-14)


OK, there have been quite a lot of significant additions and updates surrounding the intense activity of the opening of the school year. In the last couple of weeks you may have noticed the following changes; AP Worksheets o1m (Beer’s law) and o1o (organic molecules in Mass Spec) have been added (answers to 01o are […]

Developing more thoughts on Mass Spec

Excerpt Worksheet 01o

Following this original post on Mass Spec (written long before the new curriculum came into play) I have had some further thoughts on mass spec, and these extensions have been reflected both in a worksheet that I used last year, and a brand new worksheet for 2014-15. The worksheet that I used last year, AP […]

Developing more thoughts on PES

PES Mixture

When composing this post about the College Board Webinar relating to PES in February of this year, I wrote; The things to take away from these much more complicated spectra for me, are two-fold; (i) Unlike in the simulated spectra, where the intensity (height) of the peak directly relates to the number of electrons in […]

Organic Nomenclature – 25 years in

I’ve been teaching some form of Organic Chemistry at the High School and College 101 level for 25 years now, and although that doesn’t make me any kind of expert on the subject matter, it does give my a pretty decent handle on some of the basic misconceptions that students who approach the beast for […]

A few minor tweaks have been made to the Unit o notes, including an additional problem added to Task 0Biv Q1., a light editing of the History of the Atom, and the addition of a LO reference.

Why you (probably) shouldn’t worry about the new AP Chem Labs at ALL

CB Lab Manual

Let’s start with a total non-negotiable of me. Lab work has NEVER been important to AP exam success; and by success I mean scores. I think there’s a pretty good consensus on that position across most, knowledgable groups. I’ve written (and talked and presented) about this time and time again, and the essence of my […]

Chemistry Venn’s

Venn Google

Today is the 180th birthday of John Venn, the Englishman who invented the Venn diagram. Today’s Google Doodle celebrates this fact. This led me to this little piece in The Guardian – a nice read! So, OK, all well and good, but what does that have to do with chemistry? Well actually, nothing per se, but […]

Société de Chimie Industrielle Fellowship 2014-15

On July 15th I learned that I has been awarded the 2014-15 Société de Chimie Industrielle Fellowship to be completed at the Chemical Heritage Foundation in Philadelphia, PA. My accepted proposal outlines plans for a book that links the discovery of the chemical elements to the people and stories behind them, all in a way […]
