The solution to Chemical Mystery #11, which involves the Leidenfrost Effect, is presented.
What happens if you place metal that is glowing orange-hot into some water? Watch this video and find out!
What happens if you cool a Scrub Daddy sponge in liquid nitrogen (or dry ice) and subsequently strike it with a hammer? Let's find out!
As I drive home from work every day in Houston, TX I am greeted by the entrancing voice of Dr. John Lienhard, now an Emeritus Professor of Mechanical Engineering and History at the University of Houston.
In this blog post I will discuss an interview with Dr. Richard Feynman relating to magnets that explores the concept of "why?" questions in science. You will find a links to a blog post and a transcript of the interview along with ideas for how I use the video in IB Chemistry.
One of my goals for 2017 was to read more chemistry non-fiction. I accomplished that with three and a half books read. That doesn't seem like much, but given how busy I've been lately it was quite an accomplishment! I offer a brief review of my most recent book here, "The Alchemy of Air" by Thomas Hager.
The science behind the incredibly popular Scrub Daddy sponge is investigated. Part of the appeal of the Scrub Daddy sponge is that it changes from soft to hard depending upon temperature. This allows a single sponge to be transformed into a hard scrubber or soft sponge, depending upon the temperature of water into which it is placed.
Erica Jacobsen shares highlights from the December 2017 issue of the Journal of Chemical Education.
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!"
I have been in the lab conducting tests on the chemical and physical properties of various geological samples. In my investigations I’ve found that hematite is a particular mineral that is easy to acquire and quite amenable to experimentation.
