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.
2 53-minute class periods (about 2/3 of each class were used).
Happy December ChemEdX community! On December 2, 2014 I attended the second of three workshops on NGSS (Next Generation Science Standards) through our local ISD (in Kalamazoo County it is known as KRESA).
"Mr. T, you should do a review session for us before our final exam using a Google Hangout."
Cellulose nitrate (also known as nitrocellulose or guncotton) is a very flammable substance that is formed by reacting cellulose (also known as dietary fiber) with a mixture of concentrated nitric and sulfuric acids:
Whenever a serious incident takes place in a school chemistry laboratory or classroom, fire and safety officers often pontificate on the incident by quoting the Materials Safety Data Sheet (MSDS). However, how many of you have read such documents in full? In UK schools we have perhaps 200 to 400 chemicals on the shelves. Have you read the MSDSs for each chemical?
TV and movie screens today offer us a desperate fight against crazy-fast zombies, a peek into celebrities’ lives where truth is often stranger than fiction, million-dollar game shows, and more. Can portraits of science compete?
