October 2022 Xchange

The October 2022 Xchange highlights just some of the contributions that have recently been published on ChemEd X. We hope you will take a moment to check in and see what you may have missed. 


In honor of the 2022 theme for National Chemistry Week (NCW): "Fabulous Fibers: The Chemistry of Fabrics", we offer Tom Kuntzleman's post originally published in October 2016. Red dye #40 found in strawberry Kool-Aid and various cloth fibers can be used in a very simple experiment that can teach students about intermolecular forces. A video is included that describes the experiment and analysis of results. Celebrate National Chemistry Week 2022 the week of October 16–22, 2022!


This short activity uses Elmer’s Disappearing Purple Glue as an interactive introduction to acid-base indicators.


"Who Poisoned Veronica Merriweather?" is a fun application of formula stoichiometry. Students who are placed in the role of a CSI lab sleuth helping to interpret chemical data to identify a murderer. Topics covered include formula stoichiometry, percentage composition, empirical and molecular formulas and gas chromatography–mass spectrometry.


Nora Walsh outlines the interactive notebook pages she uses for her unit on the Periodic Table. All of the documents and foldables are available for download.  


Yvonne Clifford provides readers with some tips and concrete, workable ideas that have helped to fulfill her desire to provide a chemistry program that is both interesting and rigorous. This is Part 3 of a series. Also see Part 4: 


A variety of resources are available for 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.


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


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


ChemEd X invites practitioners in the chemical education community to share their experiences, knowledge and the resources they use in their classroom and laboratory.
