Identifying Unknowns: Intermolecular Forces and Properties
Ben Meacham | Sun, 06/19/2022 - 14:21
In this lab, students are presented with nine unknown substances. By performing a series of tests, analyzing chemical structures, and applying their understanding of how intermolecular forces affect the properties of a substance, students will ultimately determine the identity of each unknown.

Measuring Surface Tension to Investigate Intermolecular Forces
Ben Meacham | Fri, 05/31/2019 - 22:38
Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations. Though demonstrating the presence of these forces in a simple and explicit manner can easily be done, I wanted to change how I introduced IMFs a bit this year by focusing on a more data-to-concepts approach.
