A variety of resources are available for chemistry faculty interested in incorporating lessons and activities around art and archeology. Find out what they are in this follow up post from the inaugural ChemEd X virtual Journal Club held April 2022.
Addition of a small amount of azobenzene to eicosane can lower its melting point to where it can be melted by body heat. This can be used in demonstrations and classroom activities related to freezing point depression and phase diagrams.
Some explorations and explanations regarding superconductors and the quantum levitation (also known as quantum locking) experiment.
The concept of density is investigated regularly- in lecture, lab, or both- in Introductory (non-science majors) or the majors General Chemistry 1 courses. This post describes a short activity involving ice core density.
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.
Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
The solution to Chemical Mystery #11, which involves the Leidenfrost Effect, is presented.
