JCE 96.07 July 2019 Issue Highlights
Catalyzing Student Learning
The July 2019 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: glowmatography; examining secondary chemistry teaching; useful teaching models and tools; making science accessible; teaching kinetics; computer-based learning; explorations using x-rays; polymer chemistry laboratories; using batteries to teach; analytical chemistry; investigating scale literacy skills; printing the archives: cyanotype.
Glowmatography is a playful descriptor for the chromatographic separation of chemiluminescent dyes that are actively emitting light. Glowmatographic separations, which can be carried out using easily obtained materials (glow sticks, chalk, and acetone or alcohol), often reveal surprising color combinations of fluorescent dyes. In Simple Glowmatography: Chromatographic Separation of Glow-Stick Dyes Using Chalk, Thomas S. Kuntzleman, Kasey R. Bunker, and Ashlee A. Bartlett show how these experiments can be used to illuminate chemical topics such as chromatography, intermolecular forces, and the chemistry of glow sticks. The experiment is easy and fast to carry out and can be conducted as an in-class demonstration or performed by students in laboratory or outreach settings.
