Graphene may be the most remarkable substance ever discovered. But what's it for?
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.
Wow! Night one of the semester we did the activity Change You Can Believe In. It was my second time facilitating, so I did a much better job of directing students when they asked questions and it went much faster than last semester. I did still, as expected, have students that were frustrated. One student asked me point blank what the difference between physical and chemical changes is.
A New Year with a New Volume of Resources The January 2015 issue marks the start of the 92nd volume of the Journal of Chemical Education and is now available online at http://pubs.acs.org/toc/jceda8/92/1. This issue features colorful chemistry; using stories and writing to learn; demystifying chemistry literature; cost-effective activities and materials; experimenting with chromatography and natural products.
“On the third day of Christmas, my mailman brought to me… three gardening catalogs.” Jumping the gun? Or marketing genius? The doldrums after the holiday were a perfect time for these pages with their promise of spring. Their arrival kicked off an evening of grand plans. Somewhere along the line, chemistry crept in.
Happy New Year! For many, the beginning of a new year involves creating resolutions. And, hopefully not quitting them! Something I have resolved to do is modify the presentation and submission of lab reports.
The “bucket launch” is a fantastic experiment you can do if you have access to liquid nitrogen. Depending upon conditions, we have observed the bucket to launch anywhere from 80 to 160 feet high. See the video.
Happy New Year! Did you know that 2015 is the International Year of Light (IYL)? IYL is a “global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health1”. IYL is sponsored by several organizations with interests in science and science education, including the European Physical Society, the Institute of Physics, the American Physical Society, and the American Institute of Physics. You can find several lesson plans, videos and other educational resources on the IYL website2.
Celebrating the International Year of Crystallography
The December 2014 issue of the Journal of Chemical Education is now available for subscribers online at http://pubs.acs.org/toc/jceda8/91/12. The December issue includes content on: crystallography, assessment, career development for undergraduates, problem solving in organic chemistry, and teaching physical chemistry. This latest issue of JCE plus the content of all past issues, volumes 1 through 91, are available at http://pubs.acs.org/jchemeduc.
In a recent post, I indicated that I would make available the Chemical Reactions lab that I modified to meet NGSS guidelines. Enjoy!
2 53-minute class periods (about 2/3 of each class were used).
