The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.
A simple, but tricky experiment is displayed. Can you figure out how the trick was done?
Increasing Authenticity of the Student Experience
You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
The Human Side of Teaching and Learning
The October 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: research on: AP chemistry reform and writing instruction; novel teaching approaches; demonstrations: safety and effectiveness; augmented reality and technology for teaching; using stories and history to teach; exploring acid-base chemistry; understanding energy; biochemistry in the laboratory; teaching resources; astrochemistry resources for National Chemistry Week 2018.
A new event called "The Mole"was unveiled at BCCE 2018. I told the story of how one of my students discovered how to make marshmallows spark in the microwave oven.
Based upon reader comments on previously published, Chemical Mystery #12, I experimented and found that this demonstration is easy to pull off with relatively inexpensive and easy to find materials.
