The World's Biggest Flame Test....

Most chemistry teachers I know do flame tests with their students. It ties in well with many topics, is colorful and the kids enjoy seeing the colors and burning stuff. There are many applications. For years I always mentioned that astronomers use the idea of the flame test. They simply look at stars and examine the spectra from the light of these stars. They then match the spectra with the elements and then they can see and infer what elements are millions of light years away. I always mentioned this but never was able to demonstrate it. 

The Hindenburg

Teaching the Hindenburg disaster in the chemistry classroom.

I have always been intrigued by the story of the Hindenburg, the iconic airship that caught fire on May 6, 1937. The accident killed 35 of the 100 passengers and crewmembers on board. As a chemistry teacher, I discuss this from a chemical standpoint and the fact that the airship was filled with hydrogen, a flammable gas, rather than helium, a non-flammable gas, as today’s modern airships are.

Especially JCE: October 2016

October 2016 issue of JCE

National Chemistry Week begins on October 16 this year. It’s a time for celebration, a time to highlight chemistry’s contributions to our lives, a time to spark interest in this particular science. How will you mark the occasion? Participation in community outreach activities, perhaps? Highlighting NCW in your classes?

Extension Activity with Isotopes Matter

Isotopes Matter Interactive Periodic Table

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.

Time required: 

55-60 minutes for both parts of the extension activity
