How do Melissa & Doug’s “Water WOW!” Water Reveal coloring books work? Let's do some experiments to find out!
I Lava Particulate Models
Melissa Hemling | Tue, 05/21/2024 - 14:59
Use the classic Lava Lamp Lab to make the concept of intermolecular forces more accessible!
Exploring Color Separation in Salting-Out Experiments
Tom Kuntzleman | Sat, 05/04/2024 - 07:44
Adding dyes to salting out experiments can create a variety of interesting color effects as the dyes differentially dissolve in the aqueous and organic layers. Can this differential solubility of dyes be explained using intermolecular forces as a guide?
Refresh and Reinforce: Water Maze Challenge Brain Break Activity
Melissa Hemling | Mon, 09/18/2023 - 08:42
Brain Breaks are powerful tools in education, supported by research showing improved focus, retention, community building, and reduced stress among students. When structured using chemistry principles, like in the Water Maze Race, brain breaks can also introduce or reinforce fundamental chemistry concepts.

Adapting Card Sorts for Digital Instruction
Samantha Ramaswamy | Mon, 08/17/2020 - 16:15
Card sorts can be used to quickly assess student understanding. The author has modified two card sorts on photoelectron spectroscopy and intermoleculer forces for use either remotely or in a paperless classroom.
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.
