Amonton's Law Liquid Nitrogen Balloon Paramagnetism of Liquid Oxygen VSEPR Boxes Fifty-five Gallon Drum Crush Conductivity of Ammonium AcetatePi Bond Model Kit

Liquid Nitrogen Balloon: This demo is usually used when the gas laws are being discussed, or when states of matter are being introduced.

As a result of the parallel spin of unpaired electrons, molecular oxygen is paramagnetic and is attracted by a magnetic field.

VSEPR Boxes - A large model set is used to construct each of the 3-D VSEPR shapes

Fifty-five Gallon Drum Crush: This demo is used when the temperature dependence of vapor pressure is being discussed in a unit on the equilibrium.

Conductivity of Ammonium Acetate: usually presented when the structure of ionic compounds or the nature of the ionic bond is being introduced.

Pi Bond Model Kit: This molecular model kit is large enough to be visible by a large lecture class.

Welcome to the University of Oregon Chemistry Department Lecture

This site has been developed primarily as a resource for UO chemistry instructors, but high school and college chemistry and physical science instructors can find a lot of useful information here too. Come on in and look around! Let's do some demos. But careful and WEAR YOUR GOGGLES!
"Do not do demos unless you are an experienced chemist!"
