Two Simple and Cheap Illustrations of Phase Equilibrium and Vapor Pressure

A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.

Self-Inflatable Valentine Balloons – Chemistry is Everywhere!

Recently, while attending the High School Teacher Day at the ACS National meeting in New Orleans, we were given Wack-A-Pack™ valentine balloons and encouraged to play with them. I am a huge fan of finding chemistry in the real world and using it as an integral part of my instruction; and as we were experimenting, I was reminded of a rather fun activity I had done on Valentine’s Day with my AP students.

Confessions of a Part-Time Modeler

Two weeks of daily instruction and labs in student mode as well as teacher mode debriefing was exhausting and exhilarating at the same time.
