Color Changing Coke and Mentos

What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.

Ice Cores, Stable Isotopes, Climate Change, and Chemistry: Part 2

Two important types of information obtained from ice cores comes from the bubbles in the glacial ice and the stable oxygen and hydrogen isotopes within the frozen water molecules themselves. This post describes how the bubbles (air pocket 'fossils') and stable isotopes are used to determine the concentration of gases in the ancient atmosphere, particularly in relation to past temperatures.

Ice Cores, Stable Isotopes, Climate Change, and Chemistry

Ice core science is truly cross-disciplinary as it draws extensively from chemistry, geophysics, geology, engineering, oceanography, microbiology, statistics, a deep understanding of historical events, atmospheric science, and climate science. And general chemistry topics include solubility, concentration, phase diagrams and changes, and stable isotopes in addition to many others. Let's take a first look at how ice core science can be used in teaching chemistry.

Reimagining Chemistry Education: Systems Thinking, and Green and Sustainable Chemistry

The December 2019 issue of the Journal of Chemical Education is now available 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.

The Chemistry of Outer Space

A variety of activities performed at a science camp that relate to the chemistry of the solar system are reported. These activities could prove useful in the chemistry curriculum or in planning for National Chemistry Week in 2018, the theme of which is Chemistry is Out of This World!
