Flash Rocks from Green Chemistry and LEGO Brick Perspectives
Dean Campbell | Fri, 07/15/2022 - 23:56
Flash rocks, typically pieces of quartz that produce light when struck together, are an example of the complex phenomenon of triboluminescence. The green chemistry aspects for the flash rock demonstration are considered, and LEGO models illustrating quartz crystals, piezoelectric materials, and nonpiezoelectric materials are presented.

PFAS Guided Inquiry Activity
Melissa Hemling | Wed, 11/03/2021 - 20:32
After the AP Test last spring, I used the movie “Dark Waters”1 and this PFAS Analysis guided inquiry activity to introduce students to “Forever Chemical” pollutants in the environment (see figure 1). Students applied their knowledge about electronegativity, polarizability, and bond strength to PFAS molecules.

Kasi: A Multi-Sensory Modeling System
Doug Ragan | Fri, 04/30/2021 - 06:26
Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.
