PRODUCT DESCRIPTION

The ability to model 3D molecules and understand how this affects their polarity is the basis behind Chemistry, Biochemistry, Biology, Medicine, etc.

This is why ChemistryNinja made this fill-in-the-blank VSEPR & Polarity lesson plan for middle school Chemistry teachers. These notes first define electron domains/ groups, and then proceeds to connect this with VSEPR geometries and why molecules take up these three-dimensional shapes. Other 3D models are introduced for students to compare the pros and cons of each model and the limitations of theoretical representation of molecules.

The second part of the lesson includes a fun and inexpensive marshmallow modeling activity that can be used to replace the more expensive organic chemistry modeling kits. By participating in this activity, students will see for themselves how bonded atoms and lone pairs are arranged around a molecule to minimize repulsion between electron domains.

The last part of the lesson is connecting molecular shapes and electronegativity with polarity. By the end of the lesson, students will have a thorough understanding of molecular shapes and how this affects their polarity, which will lead up to the next lesson on Bonding & Intermolecular Interactions. Pair this lesson with the Lewis Structures lesson plan beforehand, and you'll be set!
