VSEPR theory
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.

Melissa Hemling shares her favorite manipulatives along with cheap at-home alternatives to help students visualize VSEPR.
Examining VSEPR though the Cross Cutting Concept of Patterns
Stephanie O'Brien | Sat, 12/15/2018 - 16:23
In an effort to align an old VSEPR lesson to NGSS, I told my students that we were going to look at the data available from the real molecules on the pHET simulation we were using and specifically look for patterns. Finding patterns is a cross-cutting concept; one of the three dimensions of NGSS.
