JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
Microtitrations can be used as a stand-alone lesson or as an introduction to more complex titrations. Done without expensive glassware and materials, this alternative to buret titrations is easy to implement in most classroom situations.
You're going to love this new color variation on the Density Bottle experiment!
Lead contributor Nora Walsh has compiled several activities for AP students to follow after the exam. From engaging one-day activities to Organic lessons and project ideas, Nora has you covered for a successful end of the school year with your AP students.
A pre-dinner conversation leads to a different way of thinking about quantum superposition. A meal from an idiosyncratic chef is not defined until “the reveal.” Discussion of this leads to the statement by Asher Peres that “unperformed experiments have no results.” Discussion of Peres’ statement, then contrasting versions of resultlessness in both macroscopic and quantum realms, leads to classroom discussion. This, hopefully, creates an easier and deeper understanding of quantum mechanics.
In this blog, Michael Jansen considers the significance of using proper units and their role in helping students develop a conceptual understanding of Chemistry.
Light absorbance and fluorescence were studied for a sample of the Chicago River that had been dyed green for St. Patrick’s Day. The sample had weak green fluorescence, showing that the intense green appearance of the river was in part due to the long path length of light through the water. The ability of the green color to partition into 1-octanol was also explored.
AP teacher and exam reader, Nora Walsh, shares tips on how to help your students answer AP Chemistry free-response questions. She provides examples, references, and rationale for her suggestions.
