The solution to Chemical Mystery #15: The Leaky Cup is shown here.
Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
Erica Jacobsen shares highlights from the April 2019 issue of the Journal of Chemical Education.
Did you figure out how the experiment in Chemical Mystery #14 was performed? The solution is presented here!
If you are looking to go beyond using traditional, arguably misleading, definitions of entropy involving “disorder” and “messy bedroom” analogies, the Boltzmann Bucks game fits the bill. The game, pulled from a Journal of Chemical Education article, provides a wonderful opportunity for students to more accurately conceptualize entropy.
I am already planning for my trip to Illinois in July to attend ChemEd 2019! Let me tell you why I want to attend.
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?
This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. I use this mystery as a review to prepare for assessments over the properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.
