The Liquid Nitrogen Cloud
Tom Kuntzleman | Fri, 07/26/2019 - 10:42
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
Equilibrium Snowball Fight
Josh Kenney | Thu, 06/20/2019 - 12:08
For dynamic equilibrium, I like to use a physical analogy that pits students against each other in a classroom-wide “snowball” fight. Not only is this activity great for building students’ conceptualization of dynamic equilibrium, it is also really fun!

Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
Element of the Month - Nitrogen
Stephen Wright | Sat, 04/20/2019 - 17:09
In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Nitrogen is the third in this series of elements to be discussed as part of the Element of the Month program. #IYPT
Why Do Dead Batteries Bounce? Chemistry, of Course!
Tom Kuntzleman | Fri, 04/05/2019 - 07:16
Did you know there is a simple test you can do to see if an alkaline battery is fresh or dead? All you need to do is bounce the bottom of a battery onto a hard, flat surface. Guess what causes this difference in bouncing ability between fresh and dead batteries? Chemistry, of course!
