I have tried many different methods to demonstrate or perform displacement reactions over the years with mixed results regarding one particular metal, aluminium. Based upon my experience, the behavior of aluminium in displacement reactions often confuses students.
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
Erica Jacobsen shares highlights from the January 2018 issue of the Journal of Chemical Education.
Like many schools, this year my school went 1:1. Each of our students was issued an 11 inch Chromebook with a webcam. Our upperclassmen have the the older Samsung models with a front-facing webcam and our underclassmen have the new Lenovo N22/23 models with a flippable webcam. I am a “jump in head first” type of person so I decided to go completely paperless this year. Now that I am halfway through the year (and still paperless!), I wanted to share what has been working well for me 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, I encourage you to try something like this with your students!
In the embedded video, I will walk you through a kinetics experiment we use in our Chemistry 2 (and Honors Chemistry 2) courses. The lab is called Disappearing X.
Celebrating Ninety-Five Years
The January 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: exploring magnetic properties; examining outreach practices; spectroscopy; understanding chemical changes over time; laboratory curriculum reform; teaching scientific communication; analytical chemistry activities; biochemistry laboratories; 3D printing molecular models; from the archives: chemistry outreach.
The focus of this article will be on how to incorporate the first science and engineering practice, asking questions, into your chemistry instruction. The most common professional development technique I have encountered regarding this practice is Question Formulation Technique (QFT).
One of my goals for 2017 was to read more chemistry non-fiction. I accomplished that with three and a half books read. That doesn't seem like much, but given how busy I've been lately it was quite an accomplishment! I offer a brief review of my most recent book here, "The Alchemy of Air" by Thomas Hager.
If you have never attended a BCCE, I offer some reasons to change that this summer. The conference will be in Notre Dame this summer. Please vote for the topic that you would like me to develop my presentation about.
