Photochromic glue and spring decorations
Dean Campbell | Fri, 04/02/2021 - 23:23
The many colors of springtime can be illustrated with photochromic pigments in commercial products. These products include UV beads, and more recently, photochromic glue. The glue can be used as a photochromic paint for paper or even eggs. The resulting colorful, decorative objects can be used to illustrate chemical discussions of aspects of photochemistry.

This classroom activity challenges students to figure out the volume of gaseous carbon dioxide emitted from the combustion of 1 gallon of gasoline fuel.
Energizer Lab with Virtual Options
Deanna Cullen | Tue, 03/23/2021 - 14:42
In this lab, students connect the workings of an electrochemical cell in the lab with the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process. Although this lab was previously highlighted on ChemEd X, there are now virtual options offered!
Demonstration: Colorful Sugar Density Column
Nick Thomas | Tue, 03/23/2021 - 09:52
Assembling a large graduated cylinder with colored sugar solutions of various densities is described. By filling the cylinder in the reverse order from bottom up, very little mixing occurs resulting in an attractive classroom demonstration to illustrate density. Students also have to opportunity to practice density and dilution calculations.
Teaching, The Best Kept Secret!

Developing a Model for Enthalpy of Solution—Reframing the Approach
Ben Meacham | Wed, 03/17/2021 - 10:30
Ben Meacham decided to alter his approach to teaching about enthalpy and focus on getting students to first develop the mathematical model for enthalpy of solution so they could eventually apply it to make predictions for different solutes being dissolved. In this blog post he shares the process he used with his class.
