This lesson serves as a review of ionic and covalent bonding and macroscopic properties of ionic and covalent solids. It also introduces students to a novel class of materials, cluster solids, which contain bonds with ionic and covalent properties. Upon completion of this lesson, students will be able to:
- compare particulate structures and macroscopic properties of three types of solids—ionic, covalent, and cluster solids (a novel type of solid developed recently); and
- explain how the particulate structure of each type of solid determines its macroscopic properties, including conductivity and solubility.

"I was well pleased with this lesson. I would love to have more of these the intersperse in the regular curriculum!"

"Very good lesson planning covering all the three umbrella standards: 1. Content Knowledge 2. Data Analysis 3. Application in NGSS modeling practice."
