Effective Recruiting that Led to a Decline in Diversity
Chadwick Young | Sun, 09/24/2023 - 13:05
Find out more about Nicholls State University Department of Chemistry's recruiting program involving a Roadshow and Field Days and its impact on diversity in the chemistry program.
Refresh and Reinforce: Water Maze Challenge Brain Break Activity
Melissa Hemling | Mon, 09/18/2023 - 08:42
Brain Breaks are powerful tools in education, supported by research showing improved focus, retention, community building, and reduced stress among students. When structured using chemistry principles, like in the Water Maze Race, brain breaks can also introduce or reinforce fundamental chemistry concepts.
The Floating Soap Bubble

The floating soap bubble is an impressive experiment that is surprisingly easy to carry out.
Elmer's Glue Isn't Just for Making Slime: Simple Chemical Demonstrations with Elmer's Glue
Josh Kenney | Sat, 08/19/2023 - 09:13
Josh Kenney shares three simple and inexpensive demonstrations using Elmer’s glue.
Chemical Activities Involving Reversible Thermochromic Pigments
Dean Campbell | Wed, 08/16/2023 - 07:17
The color of a thermochromic system depends on its temperature. The colors of leuco dye-based systems can also be influenced by adding acids or bases to the thermochromic reactions. These can be used to create colorful demonstrations of acid-base chemistry. Thermochromism found in color changing cups can also be used to visualize heat flow, and therefore thermodynamic principles, associated with stretching and contracting elastomers.
Not Playing with a Full Deck: Ideas For Electron-Counting Chemical Card Games
Dean Campbell | Fri, 08/04/2023 - 14:00
Ordinary playing cards can be used in games where the cards model valence electrons in atoms. These games could provide players with a fun and active way to practice counting valence electrons in simple chemical structures.
How Do Color Changing Marshmallows Work?
Tom Kuntzleman | Wed, 07/19/2023 - 12:10
With a little chemical investigation, you can figure out how Jet-Puffed's new color changing marshmallows work!
Plastic Beverage Bottles and More as Orbital Models
Dean Campbell | Fri, 06/02/2023 - 07:58
The shapes of plastic bottles can be used to represent orbitals. Using various connectors, a bit of packing tape, and a few other more specialized touches can produce large scale molecular models that feature orbitals, sigma bonds, and pi bonds.
Seashell Chemistry
Tom Kuntzleman | Thu, 06/01/2023 - 14:15
Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
