The Big Picture- My First Year Chemistry Scope and Sequence
// Monday, June 6, 2016 • Tracy Schloemer
The Big Picture: General Chemistry I thought I’d start to dive into the big picture of what I implement in my classroom. I’ll start with General/Honors Chemistry, and next I’ll write about AP chemistry. I have found it really helpful to see the scope and sequence from other teachers over time, and I hope this is helpful to you.

Solution to Chemical Mystery #6: The Case of the Collapsing Can
// Sunday, June 5, 2016 • Tom Kuntzleman
In Chemical Mystery #6, I used chemistry to crush a metal can. To do so, concentrated sodium hydroxide solution (about 35% NaOH by weight) was added to a can that was almost completely filled with carbon dioxide gas. The can was then sealed. The carbon dioxide gas in the can reacted with the added sodium hydroxide:

This past week, as part of our Thermochemistry unit, my students were completing one of my favorite Target Inquiry Labs entitled “ A Very Cool Investigation”.  We were using calorimeters, dissolving ammonium nitrate, and my students were recording the change in temperature using a digital thermometer.  Some
Shedding Light on AP Chemistry
AP Chemistry Survey
// Thursday, May 19, 2016 • Greg Rushton
Chemistry education faculty at Stony Brook and Carnegie Mellon University want to help AP chemistry teachers adapt to the new AP curriculum, and will create a new website to help support teacher needs: the APChemCollaborative (APCC). Could you please take a moment and help us understand you and your needs better, so we can create a successful design?

Doc Saves Everyone – Applying BCA Tables to Titration Calculations
// Thursday, May 19, 2016 • Dena K. Leggett
I recently stumbled across a blog about the use of BCA (Before Change After) tables for stoichiometry written by Lowell Thomson.  I was thrilled to discover ChemEd Xchange!  I wanted to share my journey, spurred on by my students, into the extensive use of the BCA
