With a Master's degree in geology, I have a deep and abiding love for rocks and minerals. The great thing about geology is, it's all about chemistry! I want to share one of my favorite links between geology and chemistry that my students think is pretty cool too.
Crystallography / Crystal Growth
Engaging Student Interest and Inquiry
The September 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: copper chemistry; safety; using brewing to teach chemistry; 3D-printed models; learning using games; open-ended approaches to teaching; innovative methods to teach biochemistry; polymer chemistry; organic synthesis labs; teaching physical chemistry; chemistry field trips.
Last year I came across a link on Twitter regarding an art installation by Roger Hiorns in England titled “Seizure.” Some of you may have seen it too – a condemned flat in London was essentially sealed off and filled with more than 75,000 L of supersaturated copper sulfate solution.
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.
This Activity illustrates sublimation/deposition with dichlorobenzene (mothballs) and evaporation/condensation with water. This Activity could be used to introduce the phases of matter and phase changes at both the macroscopic and microscopic levels.
In this Activity, students investigate the chemistry of the popular Salt Crystal Garden. They grow salt crystals by evaporation from aqueous solutions containing various mixtures of table salt, ammonia, and laundry bluing in order to determine the purpose of each component.
