The Ruben's Tube (also known as a Flame Tube) is a classic experiment used in physics classes. There's also a bit of chemistry to be learned while experimenting with a Ruben's Tube...

March came and went, and our whole world- individually and as an aggregate- was turned upside down with COVID-19 and its radically imposed isolation. Face-2-Face (F2F) instruction is now online and remote. Remote teaching. Remote learning. This post is based on the simple question- How does remote teaching change our ability to teach?
This book is filled with computer based labs that can be used in a range of classes from high school chemistry to an undergraduate course in physical chemistry. Bentham Science has generously provided free online access to the eBook through June 30, 2020.
Due to the COVID 19 crisis, ChemEd X videos and software is open access to all educators.
With the current global COVID-19 pandemic, there has been much discussion of “flattening the curve” by social distancing. These ideas can be demonstrated chemically, for example, by the iron-catalyzed decomposition of hydrogen peroxide to produce an oxygen gas foam. Decreased hydrogen peroxide concentrations, representing decreased human population concentrations from social distancing, produce oxygen gas foam, representing cases of illness, at a slower rate. A similar demonstration can be achieved using the popular Diet Coke and Mentos experiment. These simple experiments are best used as stand-alone demonstrations.
Developing Students’ Scientific Reasoning - The March 2020 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: nanochemistry; innovative curriculum; teaching with games; teaching with food chemistry and natural products; infrared applications; analysis using color, images, and visualization; environmental chemistry; computer-aided organic chemistry; synthesis laboratories; physical chemistry; graduate school climate assessment; chemical education research: introductory chemistry and student success.
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.
You may have observed a red to blue color change when you rinse your 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.
