The shapes of plastic bottles can be used to represent orbitals. Using various connectors, a bit of packing tape, and a few other more specialized touches can produce large scale molecular models that feature orbitals, sigma bonds, and pi bonds.
Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
The candy "Toxic Waste" and "Pop Rocks" are fun ways to show changes in acid base indicators. There is also an easy way to test car exhaust with an indicator.
Dean Campbell tries to use at least one demo for every class to illustrate concepts described in his chemistry courses. In this post, he includes short descriptions of the demonstrations and props he has used while teaching his collegiate General Chemistry II courses.
Experienced chemistry teachers offer tips for setting up labs!
YouTube Shorts are 60-second vertical aspect ratio videos that are meant for cell phone viewing. Since they are shorter and easier for students to access than traditional YouTube videos, Josh Kenney has started creating more of them for his blended chemistry class. Check out some of his tips for creating effective chemistry tutorials with YouTube Shorts.
