Take a walk and explore the chemical winter wonderland of snowflakes...and diamonds!
Adding dyes to salting out experiments can create a variety of interesting color effects as the dyes differentially dissolve in the aqueous and organic layers. Can this differential solubility of dyes be explained using intermolecular forces as a guide?

In this blog post, I'll discuss how I've expanded my use of model kits within my chemistry class to help explore a variety of topics with my students.
The vapor pressures of butanol and diethyl ether are compared using barometers to show the effect of hydrogen-bonding on vapor pressure.
A cast iron bomb is completely filled with ice water, then placed into a dry-ice/acetone slush and covered with a wooden box. When the water in the bomb freezes, the cast iron bomb explodes, breaking into several pieces, and destroying the box in which it was placed.
The flow of four different liquids from four pipets is started simultaneously to test their viscosity.
