As an advanced language model trained by OpenAI, ChatGPT has the potential to revolutionize the way you teach chemistry. In this blog post, Josh Kenney and Ben Meacham explore 10 ways that ChatGPT can make teaching chemistry easier and more engaging for both you and your students.
Diffusion of HCl(g) from concentrated solutions of HCl can be used to illustrate some chemistry related to the train accident in Ohio.
In a classic demonstration of energy conservation, smashing two large steel ball bearings generates sufficient heat to burn a hole through a piece of paper. Josh Kenney found this demonstration underwhelming because the paper doesn't look burned. So, he upgraded the experiment by covering the paper in Elmer's Color Changing Glue. Now, a spectacular color change reveals the increase in heat!
Michael Jansen offers one of his favorite demos - producing liquid CO2 from dry ice.
TikTok and YouTube Shorts are video sharing platforms for short-form, vertical aspect videos. Both of these services are growing more quickly in popularity compared to more traditional video formats. Josh Kenney shares some of the ways that he is using short-form videos in his chemistry class and shares a free resource (an exam review worksheet that links to a YouTube Shorts playlist through a QR code).
Egg cartons and small objects such as milk jug caps or plastic eggs can be used to illustrate chemical concepts. The egg cartons can be cut into trays to represent atoms or to represent energy levels associated with atomic orbitals. The plastic caps or eggs distributed among the dimples of the trays can be used to represent electrons or pairs of electrons.
Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.
Describing the number density of molecules involved in chemistry demonstrations while presenting those demonstrations can help to convey concepts such as the small size of molecules and how the distance between molecules can vary during change of physical state.
Upon reading the product label and the drug monograph, it was evident that this pharmaceutical formulation, sold in Canada as Pico-Salax and used in the US as Prepopik, both manufactured by Ferring, would be a useful case study for several introductory general chemistry topics.
Short descriptions of demonstrations and props that Dean Campbell has used while teaching his collegiate Environmental Chemistry course. Many of these examples are also suitable for use in high school and collegiate General Chemistry courses.
