text: Geometric Approach to Lewis Structures (over 3D models and lewis structures)
// Tuesday, April 12, 2016 Lauren Stewart
If you look at any chemistry textbook, you will see Lewis structures introduced long before electronic and molecular geometries. This makes sense since you need Lewis structures to determine molecular geometry.
AACT

I wonder how many of the ChemEdX readers are also members of AACT? The American Association of Chemistry Teachers has been a long time coming and is in its second year of operation now.
ap exam date May 2
// Monday, April 4, 2016 Tracy Schloemer
It’s review season for AP courses! I have a love/hate relationship with the date of the AP Chemistry exam. On one hand, it’s SO early. On the other hand, because it’s the first exam, my students actually study for it (compared to later in the AP exam season when students are like, “I’m done. I don’t care anymore.”).
Smartphone spectrophotometer

A smartphone can be used in a remarkably simple and inexpensive way to teach your students about absorption spectroscopy and Beer’s Law. In short, light reflected off of colored construction paper is passed through a sample and detected by an RGB application on a smartphone.
coding
// Wednesday, March 23, 2016 Lauren Stewart
Computer coding has been getting a lot of attention with the Hour of Code movement and President Obama’s recent “Computer Science for All” initiative. Just like it is no longer solely the job of the English teacher to teach language and communication skills, it is no longer solely the job of the computer science teacher to teach programming skills.
periodic table apps
// Tuesday, March 22, 2016 Doug Ragan
Upon sharing my array of apps with some future chemistry teachers, they asked why so many Periodic Tables?  My response was “Well not all periodic tables are the same”, upon which was followed by several blank stares… Let me explain:  I currently have the following periodic table apps loaded on my iPad:
Tell me a story

Let’s get a coffee and you can tell me your story. Let me explain why I don’t have my homework. Our data might not look good, but wait till you hear what happened!
