public understanding

For the past few years when I’ve been covering introductory concepts in thermodynamics, I’ve made a connection to climate change. My students and I calculate the energy that has been gained by Earth’s oceans as heat, using the following equation that is familiar to students of introductory and general chemistry:

Deanna Cullen, Scott Milam, Doug Ragan, and I recently published an article, Rapid Formation of Copper Patinas: A Simple Chemical Demonstration of Why the Statue of Liberty Is Green, in the Journal of Chemical Education¹ that describes how to create a blue-green

A good deal of evidence indicates that wearing facial masks inhibits the spread of COVID-19.^1-4 The spread of the virus appears to occur via airborne transmission.

In Chemical Mystery #17, shavings of Dial soap are added to samples of Aquafina and Evian drinking water. Upon blowing into each mixture with a straw, only the Aquafina water produced stable bubbles. Why is this the case?

With most of us stuck at home to combat the recent outbreak of COVID-19, I thought it might be a particularly good time to do some simple chemistry experiments that use only items found around the home (well, more like purchased at my local grocery store).

Berries are red, berries are blue…I’ve got a berry surprise for you! DESCRIPTION: 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? Read on to learn about the blueberry surprise!

The bush fires in Australia have killed an estimated 500 billion animals and caused widespread damage. Can these fires be connected to greenhouse gas emissions and human-caused climate change? What kind of warnings have scientists issued about the possibility of such fires in relation to climate change?

I recently developed a demonstration that I’d like to call “The Chemical Laser Show”.

I recently tried an experiment in class that works well as a chemistry demonstration for Halloween. In fact, I recently performed it at our annual Halloween / National Chemistry Week chemistry demonstration show. The experiment is very easy to carry out. I call it “The Devil’s Milkshake”. Check it out in the video below.
