Nora Walsh outlines the interactive notebook pages she uses for her unit on Bonding. All of the documents and foldables are available for download.
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.
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.
In this ChemBasics Talk, Nora Walsh offers everything necessary to plan a unit on the topic of chemical bonding and naming including introductory and discovery activities, manipulative activities, practice problems, her favorite online teaching resources and more. Watch the recording and access resources she shared.
This is a series of experiments, PhET Interactive Simulation activities, and clicker questions to relate macroscopic and molecular representations of homogenenous solutions. Graphing skills are also used.
