VSEPR Flat Packs: An Economical Model Kit
Kathryn Rust | Tue, 06/13/2023 - 09:59
Molecular geometry is a center piece to a student’s understanding of intermolecular forces. Unfortunately, many students don’t have the special skills to “see” the geometry without a model kit. Check out this inexpensive take-home model kit!
1, 2, 3: Hybrid Dimensions
Joseph Lomax | Sat, 11/12/2022 - 22:28
Sometimes the obvious is the most difficult to see. Even after teaching for four decades, there is still something to learn from students. What did I recently learn? Check out my post.
Kasi: A Multi-Sensory Modeling System
Doug Ragan | Fri, 04/30/2021 - 06:26
Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.

Lewis Dot, VSEPR Shape, Polarity and Intermolecular Forces Activity Sheet
Estelle Lebeau | Thu, 05/23/2019 - 09:00
Determination of Lewis Dot structures and visualization of the shapes of molecules using VSEPR theory is an example of an abstract concept that students often find difficult to learn. I have found it useful to have a single worksheet/packet that my students can add to as we cover Lewis dot structures, resonance, VSEPR shapes, polarity, and intermolecular forces.
