Water Crystallization & Hydrogen Bonding (DIGITAL DOWNLOAD)

Hits the standard: ESS2-5: Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.
Lesson Brief: Among the many ways that water influences the surface of the earth are freeze-thaw cycles that contribute to weathering and soil formation, and the accumulation of snow and ice, and the way that ice forms to create a floating solid. Understanding the way that water molecules join to form a crystalline structure is a key to understanding how water can break bedrock and form complex geometric shapes. This lesson examines how the change from unordered water molecules into the regular crystal lattice structure of frozen water gives ice properties that lead to geological processes such as soil formation and have helped shape the biology of Earth.
