How do Melissa & Doug’s “Water WOW!” Water Reveal coloring books work? Let's do some experiments to find out!
intermolecular forces
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.

Did you figure out how to create a multi-colored mixture? Check out the solution to Chemical Mystery #19: Multi-colored Mixture!
Intermolecular Forces and FLIR Cameras
Chad Husting | Mon, 03/15/2021 - 10:23
Infrared technology (FLIR Cameras) can be used to investigate intermolecular forces.
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.
Solution to Chemical Mystery #15: The Leaky Cup

The solution to Chemical Mystery #15: The Leaky Cup is shown here.
Soap Making
Heidi Park | Sat, 07/08/2017 - 11:56
Heidi Parks offers a soap-making lab or activity that can be run in a chemistry class with 25-30 students working at the same time. She usually does this activity right before spring break, as it provides enough time for the soap to harden and cure (high school students are impatient to use their soaps right away, which you should not do with cold process soap). She has used this soap making activity at different points in the curriculum: during intermolecular forces, during acids and bases, and during stoichiometry.
