Solubility, Stoichiometry and Non-stoichiometry
// Monday, January 24, 2022 • Joseph Lomax
The importance and difficulty of concepts of the electrolyte came home to me while I was helping a student. She was having difficulty with the idea of an electrolyte. Specifically, she 1) misapplied the maxim "Like dissolves like," and 2) could not distinguish between the terms "dissolve" and "dissociate". In my knowledgeable na

Introducing the Quantum Mechanical Model using Photoelectron Spectroscopy
// Monday, December 13, 2021 • Kristen Drury
After taking two courses with American Modeling Teachers Association (AMTA) I gained more insight and appreciation for evidence driven teaching. In the AMTA curriculum students are provided ionization energy values to help them construct Bohr diagrams and explain why multiple energy levels are required in the Bohr model.
