Solubility, Stoichiometry and Non-stoichiometry
Joseph Lomax | Mon, 01/24/2022 - 19:40
The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.
How Does the Rainbow Candy Experiment Work?

The Devil's Milkshake is a simple, yet interesting chemistry experiment that fits well as a Halloween demo.
Exploring the Diet Coke and Mentos Experiment
Tom Kuntzleman | Tue, 05/09/2017 - 07:39
I think this experiment provides a fantastic vehicle to involve students of all ages in small, hands-on and exploratory research projects. Like many others, my students and I have investigated various aspects of this interesting fountain.
Homogeneous Solutions using PhET Interactive Simulations and labs
Trish Loeblein | Mon, 09/16/2013 - 15:19
This is a series of experiments, PhET Interactive Simulation activities, and clicker questions to relate macroscopic and molecular representations of homogenenous solutions. Graphing skills are also used.
Fun with M & M's
