Solutions of copper (II) dissolved in acetone are easy to prepare, and can display orange, yellow, green, and blue color depending upon conditions. Such solutions allow for a variety of demonstrations and experiments that illustrate principles of chemical equilibrium.
I observe a red to blue color change when I rinse my bowl after eating frozen blueberries. Sounds like an acid-base reaction, doesn’t it? Well, read on to learn about the blueberry surprise!
A lot of time is spent assessing students but how much time is spent assessing ourselves and our peers? Some faculty take departmental evaluations seriously and professionally while others prefer not to for a variety of reasons. What happens when a faculty member introduces evaluation guidelines into a department that had none previously? Read and find out.

Have you heard that TERC, a nonprofit, has launched a STEM Teacher Leadership Network funded by the National Science Foundation? The online community is for aspiring or current teacher leaders, researchers and administration to improve STEM education, effect policy and discuss the changes to the future of STEM education in a collaborative online collegial network.
Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.
Reimagining Chemistry Education: Systems Thinking, and Green and Sustainable Chemistry
The December 2019 issue of the Journal of Chemical Education is now available online to subscribers. In response to a call for papers, chemistry educators from around the world have contributed articles to the Journal collected in the December edition as special issue on systems thinking, and green and sustainable chemistry.
This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.
The flipped classroom of today looks vastly different from its initial form. Originally, class time was primarily used to complete homework assignments; however, more effective active learning practices tend to dominate class time in modern applications of the model. Although the flipped classroom has improved over the years, several challenges persist.
