ChemEd X contributors offer their ideas and opinions on a broad spectrum of topics pertaining to chemical education.
Blogs at ChemEd X reflect the opinions of the contributors and are open to comments. Only selected contributors blog at ChemEd X. If you would like to blog regularly at ChemEd X, please use our Contribution form to request an invitation to do so from one of our editors.
For your enjoyment, we present lists of chemically-related words that end in the letters “-cation” but do not actually refer to the positively-charged chemical species. The lists are available for download in the Supporting Information.
Chad Husting tries out some micro-scale labs.
Practice problem answer keys that provide correct and incorrect answers increase student metacognition and lead to more thorough learning.
Bring the fun of the viral word game "Wordle" into the chemistry classroom!
Recently, Josh Kenney took time from his regular scheduled chemistry curriculum to investigate a student's claim that chocolate cake was an acid-base indicator.
In two connected ways, thermodynamics describes how both physical or chemical processes spontaneously trend towards equilibrium. This post is concerned with showing how free energy (ΔGrxn) changes as the reaction quotient (Q) changes as both trend towards the special condition, equilibrium, described by the constant K.
Tom Kuntzleman conducts a safer "mercury-like" beating heart experiment with an added splash of gratefulness.
How to build confidence in your students and minimize aggression.
Balloons that inflate using carbon dioxide produced from the reaction of citric acid and sodium hydrogen carbonate can be used to demonstrate a number of aspects of chemistry. Gas laws were used with the balloons to illustrate limiting reactants, molar mass of gases, and rockets. The endothermic reaction in the balloon was visualized with an infrared camera, and the Green Chemistry aspects of these balloons were considered.
