High School (SCI) Earth Space Science Standards
[ESS2] Earth's Systems
SCI-HS.ESS2.05 Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.
Clarification Statement:Earth Science/Environmental Science: Emphasis is on mechanical and chemical investigations with
water and a variety of solid materials to provide the evidence for connections between the hydrologic
cycle and system interactions commonly known as the rock cycle. Examples of mechanical
investigations include stream transportation and deposition using a stream table, erosion using
variations in soil moisture content, or frost wedging by the expansion of water as it freezes. Examples
of chemical investigations include chemical weathering and recrystallization (by testing the solubility
of different materials) or melt generation (by examining how water lowers the melting temperature of
most solids). Disciplinary Core Ideas ESS2.C: The Roles of Water in Earth's Surface
-The abundance of liquid water on Earth’s surface
and its unique combination of physical and chemical
properties are central to the planet’s dynamics.
These properties include water’s exceptional
capacity to absorb, store, and release large amounts
of energy, transmit sunlight, expand upon freezing,
dissolve and transport materials, and lower the
viscosities and melting points of rocks.
