Decorative beads are tested for the presence of iron pyrite, or FeS2, in an activity well-suited for the National Chemistry Week theme of "Chemistry Rocks!"
Celebrating the Value of Chemistry
The October 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: geochemistry in action; research on effective teaching and study approaches; keeping education and chemistry relevant; communication and writing; spectroscopy; chromatography; synthesis; teaching resources; mining the archive: chemistry rocks!
Check out these experiments that are very easy to perform and also related to the themes for National Chemistry Week in both 2017, Chemistry Rocks and 2018 Chemistry is Out of this World!
Enhancing Student Success in Chemistry
The September 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: student thinking and student success; computational thinking; using games to teach: developing and making tools for teaching; understanding catalysis; green chemistry; food chemistry in the laboratory; exploring edible fats and oils; NMR spectroscopy; laboratory cross-course collaboration; physical chemistry; distilling the archives: scents and smellability; announcing the search for the next Editor-in-Chief.
I recently watched a video in which a chemist (who goes by the nickname “NurdRage”) activated a chemiluminescent reaction by vapor deposition. I wanted to try it out for myself! Unfortunately, oxalyl chloride is toxic, corrosive, and a lachrymator. Thus, the experiment conducted by NurdRage needs to be conducted in a hood, and it is not particularly amenable to simple presentations. I began to wonder how I could create this vapor activated chemiluminescence using simple materials.
In Chemical Mystery #10, plastic straws are observed to “magically” change color when waved in the air. Check out the explanation and the video.
In this simple trick, colors are made to "magically" appear and disappear on a straw. This science experiment is very easy to do...if you know your chemistry!
Lasting Value and High Impact
The May 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: project- and inquiry-based laboratories; measuring value and impact; research on core ideas and clickers; new twists on classic activities; understanding diffraction; acid-base chemistry; teaching informed by technology: flipped learning, biochemistry labs, and scientific computing for chemists; from the archives: chemistry helps feed the world.
I think this experiment provides a fantastic vehicle to involve students of all ages in small, hands-on and exploratory research projects. Like many others, my students and I have investigated various aspects of this interesting fountain.
Resources To Inform Teaching and Learning
