Learn a bit about the chemical reactions that occur during a lightning strike, and how you can demonstrate these reactions in your classroom.

Use a simple experiment to get to know students, demonstrate experimental design and discuss classroom policies about cell phones.

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.

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.

The 2023 cycle for the Presidential Award for Excellence in Mathematics and Science Teaching has opened. Read through to learn more about the application, the process, some helpful tips, and reasons why you should apply.

Embarking on a new learning journey is always better with the help of others.

The importance of surface area can be illustrated by adding spherical solids at known sizes and temperature to other substances at different temperatures and then monitoring the rates of temperature changes of the system over time. Larger spheres (with less surface area per sample) exchanged heat with water more slowly than smaller spheres, and less thermally conductive glass spheres exchanged heat with water more slowly than iron spheres. Additional, more colorful demonstrations are described in which small glass spheres cool thermochromic plastic cups more quickly than larger glass spheres.
