magnetic properties

I was mesmerized the first time I saw the quantum levitation (also known as quantum locking) experiment, in which a disk containing a superconductor hovers above some magnets. The superconductor can even glide freely over a track of magnets – even upside down (VIDEO 1).

National Chemistry Week (NCW) is only a little over a month away! It will be held October 20-26, and this year’s theme is Marvelous Metals!

In the January, 2018 issue of the Journal of Chemical Education, Jeffrey Statler describes several experiments that can be conducted with liquid air.¹ He demonstrates that liquid air can be easily collected by simply immersing a test tube in liquid nitrogen, which has a

In preparation for the National Chemistry Week (NCW) theme of “Chemistry Rocks!”, I have been testing various decorative beads for the presence of certain minerals. Several beads of this type are available at craft stores such as Michael’s and JoAnn Fabric.

The theme for National Chemistry Week (NCW) this year is Chemistry Rocks!¹ During NCW, which this year will be held October 22 – 28, many chemical educators will be focusing on the chemistry of rocks and minerals. To prepare for NCW, I’ve been in the lab conducting tests on the chemical and physical properties of various geological samples.
