Finding Flash Rocks

Flash rocks were discussed in a previous post as stones made of quartz that produce light by triboluminescence when struck together. This post provides some description of their origins and tips on how to find them, making connections to some of their properties.

ChemEd X Talk: Assessment Tools to Examine Students’ Reasoning with Multiple Representations of Bonding

Learning chemistry requires students to become fluent in the symbolic language of chemistry. Developing expertise requires that students move beyond manipulating equations and symbols to create explanations with particulate models of matter to explain their observations in the laboratory. Failure to accurately interpret and connect these multiple representations of matter and Johnstone’s Domains – macroscopic, particulate, and symbolic - is one source of students’ misconceptions. We hope you will join us on September 29th at 8pm EST to learn more about this topic from Stacey Lowery Bretz.
