A periodic table project...
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.
I have in my library several chemistry textbooks from before 1860, but "Chemistry No Mystery" is not one of them. Reflecting as they do an approximation of the chemistry known at the time, they provide insight about the history of both science and pedagogy. I learned about this one from my friend Ron Perkins, a skilled chemical demonstrator, and "Chemistry No Mystery" is the most demonstration-oriented of the old textbooks I have seen.
MIT’s Dan Nocera (soon to be Harvard’s) gave a seminar in our department about a year and a half ago, and I heard him speak again in ACS President Bassam Shakhashiri’s ”Presidential Symposium on Catalysis” at the Spring national meeting in San Diego. The chemistry he described is a beautiful example of how fundamental research can potentially impact the lives of billions of people. Dan and his research group have discovered what appears to be an inexpensive, self-healing, air-tolerant catalytic system to split water into hydrogen and oxygen. We have seen before grand announcements about photocatalytic water-splitting systems, but this one appears not to suffer the fatal flaws of the others – requirement of pure water, expensive ingredients, and short duty cycles.
Suppose that the earth’s atmosphere continues to warm, beyond the levels that we know are already inevitable. Suppose that the arctic permafrost melts, releasing millions of tons of methane, which is about thirty times more effective at warming than is carbon dioxide, as well as much CO2 as is already in the atmosphere. Within a few years, the mean temperature rises by five degrees Celsius or more, sea levels rise, crops fail and millions starve.
The NEXT GENERATION SCIENCE STANDARDS are now available for review until June 1st. Science educators at all levels are encouraged to review the document and complete the associated survey.
JCE Online offered subscription-based access to a collectiion of titles named JCE Web Software. You can find the JCE Web Software collection at the LEARN menu item in the site menu bar. Access to the titles in the collection is still restricted to JCE Web Software subscribers.
All academics are encouraged to become reviewers to keep abreast of new developments in their field, to help shape the direction of their discipline, and as their scholarly responsibility. The article has many more details and is worth a quick look.
What is this? Art? Humor? Sports? Math? – or all of the above? With baseball season starting, I found it irresistible to recommend “Flip Flop Fly Ball”, which reminds me in some ways of the beautiful series of graphical exemplar books by Edward Tufte, and in others of Michael Lewis’ MoneyBall (the book, more than the movie, although the movie was ok).
Welcome to the Chemical Education Xchange (ChemEd X)! We hope to strengthen the community of chemistry educators by providing learning resources and forums for discussion and collaboration right here at this site. Take a look, and join in.
