Layer intermolecular interactions into your practical lessons with these chromatic experiments

Intermolecular forces can be an abstract concept for learners to grasp. Having a practical to clearly show these forces at work not only helps learners visualise what can be an abstract concept, but can also be deeply engaging for students, ensuring they don’t forget the topic in a hurry. Find out how chemistry teacher Declan Fleming has cleverly and colourfully made intermolecular forces visible with this quick demonstration, and use the accompanying technician notes to use this practical in your classroom.
