January 2018 Xchange

Dear ChemEd X Community,

With the holidays and celebrations of the past month, you may have missed some excellent ChemEd X posts. I have highlighted just a few of them here in the January Xchange. I hope you will take a look and find some inspiration that fits your needs. Is there a topic that you would like to learn more about, but you are struggling to find a resource? Or, maybe you are considering submitting a paper? I hope you will feel free to contact us through the ChemEd X  and let us know.       

Wishing you a peaceful 2018,

Deanna Cullen



Tools for Integrating Green Chemistry in Your Classroom features a hybrid of published Journal of Chemical Education articles, Beyond Benign lesson plans and additional supporting resources. The goal of the conference is to spark interactive dialogue related to increasing the adoption of green chemistry principles and practices throughout the K-20 chemistry education spectrum. Registration is now open. The conference runs January 29 through February 13. 


The focus of this article will be on how to incorporate the first science and engineering practice, asking questions, into your chemistry instruction. A common professional development technique regarding this practice is Question Formulation Technique (QFT). The author shares her experience with the practice.


When her school changed to a 1:1 technology program this year, the author decided to go completely paperless. Halfway through the year (and still paperless), she shares what has been working well and where the snags have been.


Whether you are looking to add a bit more scientific inquiry to your labs or simply looking for a great stoichiometry lab that can be added to your collection, you will be interested in considering this investigation. 


The science behind the incredibly popular Scrub Daddy sponge is investigated. Part of the appeal of the Scrub Daddy sponge is that it changes from soft to hard depending upon temperature. This allows a single sponge to be transformed into a hard scrubber or soft sponge, depending upon the temperature of water into which it is placed.


Is it time for chemistry teachers to move beyond the Le Châtelier Principle as justification for why disturbances to equilibrium systems cause particular “shifts”? The author shares his new approach to teach equilibrium and provide his students with a more rigorous understanding of the concept. 


Erica Jacobsen regularly highlights JCE articles that are of special interest to high school teachers. While reading the article she discusses in this edition, the answer to the questions: "Where do students do most of their learning about science? In the classroom?" surprised her.
