A description of a quick and easy lesson that is sure to add some spark into your next lesson on stoichiometry.
Educational Opportunities and Challenges
The November 2015 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: materials science; polymer chemistry activities; green chemistry; biochemistry in the laboratory; research on student attitudes and the transition from high school to college chemistry; assessment; computer-based learning and computations; from the archives: chemistry YouTube videos.
You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.
Celebrating National Chemistry Week 2015: Chemistry Colors Our World
The October 2015 issue of the Journal of Chemical Education is now available online to subscribers. National Chemistry Week, a community-based annual event uniting ACS local sections, businesses, schools, and individuals in communicating the value of chemistry in our everyday life, is being celebrated October 18–24, 2015 with the theme “Chemistry Colors Our World”. Articles in this issue can help you make the most of this annual celebration.
I need to thank a lady from Texas. We had just finished the classification of matter and I have always wanted to follow up with a distillation. I have talked about it and once I even got some extremely expensive glassware that I carefully set up, managed to break by third bell and really ticked off the AP teacher. At Chem Ed 2015, a teacher from Texas showed me this quick and dirty way to do a distillation that the kids can do. First, let me say that this is not my idea. I forgot her name. "Lady from Texas", let me just say "thank you". If you are reading this, please shoot me an email and I will be more than happy to give you credit. It worked really well.
Most chemical educators will agree that exciting demonstrations are excellent motivators to create interest in science. They are also a way to create interest in the community, motivate the student-demonstrators, and perhaps to make a little money to support special activities of an ACS Chem Club. Chemical demonstration shows, organized around holidays or other special occasions have a long and honored history. Pacifica High School (Garden Grove, CA) took its inspiration from the lecture-demonstrations of Michael Faraday, given during the Christmas holidays of 1860-61. (The Chemical History of A Candle).
