As we continue to make plans to teach during these uncertain times we have been compiling a list of both new and previously published ChemEd X posts and resources that will be useful to readers while teaching during the COVID-19 pandemic. Do you have an activity, strategy or idea to share with the community? Is there a resource you would recommend? We welcome contributions. This list will grow, so check in again to see what has been added.
Learn a simple way to relate the heat equation (Q = mc∆T ) to climate change.
Spectroscopy-based experiments are commonplace in college labs. This out-of-classroom activity post provides links to applications of spectroscopy in a diverse spectrum of disciplines and work fields.
Come explore the “Fire and Ice” pedagogic field laboratory. Follow suggested pathways and perspectives, or blaze your own trails. Visit for 10 minutes or for hours.
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.
Determining the empirical formulas of ionic compounds based on charge balance is often a challenge for beginning chemistry students. Many visual aides have been developed for this purpose, from repurposing commercial interlocking bricks to custom 3-D printed bricks. This article describes yet another option– upcycled can carriers.
The use of anthocyanins in red cabbage extracts as pH indicators has long been a popular classroom activity. Flowers, fruits and vegetables contain a diverse range of anthocyanins. This investigation explores further applications of plant-derived dyes including reversible reactions based on oxidation/reduction chemistry and other reactions to illustrate colour changes that are not solely dependent on pH change. By using household materials and plant dyes, this investigation may potentially be completed at home if necessary.
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.
Two important types of information obtained from ice cores comes from the bubbles in the glacial ice and the stable oxygen and hydrogen isotopes within the frozen water molecules themselves. This post describes how the bubbles (air pocket 'fossils') and stable isotopes are used to determine the concentration of gases in the ancient atmosphere, particularly in relation to past temperatures.
